Map the Block › About the data
What data is on Map the Block?
Map the Block puts 207 layers of public data about U.S. neighborhoods on one free map: crime by county and city, income and poverty, home values and rent, health, schools, religion, elections and campaign money, gun laws, natural hazards and community places. Every layer below names its official source and coverage, says whether it was checked against a second source, and links straight to it on the map.
Last updated . Counts are shaded as raw numbers; rates and shares appear in each popup. We never map individual people.

What economic data is on the map?
6 layers: Household income, Unemployed people, Households on SNAP / EBT, People in poverty, Unemployed people, latest month (by county), Children in poverty.
Household income
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B19013 (median household income)
Why we trust it: Matched exactly against a second Census table and a random sample re-queried from the Census API.
Unemployed people
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B23025
Why we trust it: Matched exactly against a second Census table; county figures compared with Bureau of Labor Statistics data.
Households on SNAP / EBT
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B22003 (households receiving SNAP in the past 12 months)
Why we trust it: Census figures matched exactly; county totals compared with USDA SNAP administrative counts.
People in poverty
Number of people living below the federal poverty line (about $31,200 a year for a family of four in 2024). Near colleges, counts can look high because students count. Shading is the count; the popup also gives the share.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B17020
Why we trust it: Checked against Census's own published percent tables for the same areas (every test tract and county matched within rounding); county figures also compared with the Census SAIPE poverty model.
Unemployed people, latest month (by county)
Number of people out of work and looking, from the federal monthly county estimates. Newer than the Census-survey layer 'Unemployed people' (a 2020-2024 average) but county-only, not seasonally adjusted, and the latest month is preliminary.
Source: U.S. Bureau of Labor Statistics, Local Area Unemployment Statistics (LAUS), county data, not seasonally adjusted. Public domain.
Why we trust it: County figures add up to BLS's own state figures within 0.06% in every state (August 2026: 7,464,253 vs 7,464,274 nationwide).
Open “Unemployed people, latest month (by county)” on the map → · Unemployment by County: Latest Month →
Children in poverty
Number of children under 18 living below the poverty line. Small tracts have few children, so many tracts are hatched as less reliable (73% in the research/24 test). Shading is the count; the popup also gives the share.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B17020
Why we trust it: The count is the numerator of the share tested in research/24 (matched Census table S1701 in every test tract and county); county figures were also compared with the Census SAIPE child-poverty model.
What housing data is on the map?
8 layers: Home values, Houses over $1,000,000, Public housing developments, Typical rent, Renter households paying 30%+ of income on rent, Homeowner households and 2 more.
Home values
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B25077 (median value, owner-occupied)
Why we trust it: Matched exactly against a second Census table and a random sample re-queried from the Census API.
Houses over $1,000,000
How many owner-occupied homes their owners value at $1,000,000 or more, and their share of all owner-occupied homes. Values are what owners told the Census survey their home would sell for, not appraisals or sale prices. Rented homes and vacant homes are not included. Neighbourhood figures are survey estimates; faded areas have a wide margin of error.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B25075 (value of owner-occupied homes)
Why we trust it: Matches the Census Bureau’s own published share of homes worth $1,000,000 or more (table DP04) to within 0.1 point in every county and in all 24,176 neighbourhoods checked in CA, NY, TX, WA and MA.
Public housing developments
Buildings run by public housing agencies. Section 8 voucher holders live in private rentals; their addresses are private and never shown.
Source: U.S. Department of Housing and Urban Development (HUD), Public Housing Developments
Why we trust it: Record count matched HUD's service; unit totals compared with HUD's Picture of Subsidized Households.
Typical rent
Middle monthly rent including utilities: half of renters pay more, half pay less. Census tops out at $3,501, so “$3,501” means $3,501 or more.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B25064 (median gross rent)
Why we trust it: Checked against Census's own published percent tables for the same areas (every test tract and county matched within rounding).
Renter households paying 30%+ of income on rent
Number of renting households that spend 30% or more of their income on rent and utilities (HUD's “cost-burdened” line). Shading is the count; the popup also gives the share.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B25070
Why we trust it: Checked against Census's own published percent tables for the same areas (every test tract and county matched within rounding).

Homeowner households
Number of occupied homes lived in by their owner. Shading is the count; the popup also gives the share.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B25003
Why we trust it: Checked against Census's own published percent tables for the same areas (every test tract and county matched within rounding); also compared with the 2020 Census full count.
Vacant homes
Homes with nobody living in them when the Census survey was taken, and their share of all homes. The Census counts a home as vacant for many reasons: for sale or for rent, sold or rented but not yet moved into, seasonal or vacation homes, and “other vacant” homes such as abandoned or neglected ones. Beach and ski towns can look high because of holiday homes. Neighbourhood figures are survey estimates; faded areas have a wide margin of error.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B25002 (occupancy status)
Why we trust it: Matches the Census Bureau’s own published vacancy rate (table DP04) to within 0.1 point in all 624 neighbourhoods checked.
Households with home internet (broadband)
Number of households with any broadband subscription: cable, fiber, DSL, satellite or a cellphone data plan. Shading is the count; the popup also gives the share.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B28002

What education data is on the map?
4 layers: Public schools, Colleges and universities, Private schools, Adults with a college degree (bachelor's or higher).
Public schools
Every public school in the 2024-25 federal school list (about 102,000), with its school district's budget. Budgets are published per district, not per school, so each school shows its district's totals and its average spending per student. U.S. public schools spent $842 billion on day-to-day costs in 2024 (Census). About 1 in 10 schools (mostly charter and state-run schools that are not part of a district in the Census survey) show no budget. Dense areas are thinned when zoomed out; zoom in to see every school.
Source: National Center for Education Statistics, EDGE public school locations 2024-25; budgets: U.S. Census Bureau, Annual Survey of School System Finances, fiscal year 2024
Why we trust it: 84–89% of schools in Texas, Ohio and Colorado have a matching school in OpenStreetMap. Budgets: district figures add up to 98.8% of the Census Bureau's published U.S. total for day-to-day school spending ($832 billion of $842 billion; the rest is state-run schools); New York City works out to $40,912 per student.

Colleges and universities
Colleges, universities and trade schools in the 2024-25 federal list (about 6,600), including beauty and technical schools.
Source: National Center for Education Statistics, EDGE postsecondary locations (IPEDS) 2024-25
Why we trust it: 48–63% have a matching campus point in OpenStreetMap within 1 km (big campuses are mapped at different spots).
Private schools
Private schools that answered the federal Private School Survey for 2023-24 (22,510). NCES estimates about 30,550 private schools in all, so roughly 1 in 4 is not shown. Private schools do not publish budgets to any government; nonprofit ones file IRS tax returns (Form 990) with their total spending.
Source: National Center for Education Statistics, EDGE Private School geocodes (Private School Survey 2023-24)
Why we trust it: The count is 74% of NCES's own published estimate (30,553; NCES 2026-015, Table C-15), and between 53% (MT) and 86% (NE) by state. 42–59% of ours in Texas, Ohio and Colorado have an OpenStreetMap school within 300 m.
Adults with a college degree (bachelor's or higher)
Number of adults 25 and older with at least a 4-year college degree. Shading is the count; the popup also gives the share.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B15003

15 layers: Hospitals, Free & low-cost clinics (community health centers), Nursing homes (CMS star ratings), VA health care, Adults with diabetes (estimated), Adults with obesity (estimated) and 9 more.
Hospitals
Open hospitals nationwide. “Emergency room” comes from Medicare's hospital data where we could match the hospital (about 6 in 10); call 911 in an emergency.
Source: FEMA hospital locations (HIFLD/RAPT); emergency services from CMS Hospital General Information (July 2026)
Why we trust it: 87–90% of hospitals in Texas, Ohio and Colorado have a matching hospital in OpenStreetMap.
Open “Hospitals” on the map → · Hospitals Map: Every U.S. Hospital With an ER →
Free & low-cost clinics (community health centers)
Federally funded community health centers and look-alikes. They must see everyone, insured or not, and charge on a sliding scale by income; many also offer dental, mental health, addiction care and pharmacy. Services and hours vary by site, so call first. Sites that do not bill Medicare (some school-based and mobile clinics) are not listed.
Source: U.S. Centers for Medicare & Medicaid Services, Medicare provider enrollment: Federally Qualified Health Centers (July 2026); addresses placed with the U.S. Census Bureau geocoder
Why we trust it: 9,605 of 10,815 health center addresses placed; 99.8% land inside their own state (the rest are river-border towns). Spot-checked addresses in Poughkeepsie, NY and Trenton, FL sit at the right street address.

Nursing homes (CMS star ratings)
Every nursing home certified for Medicare or Medicaid, with CMS's 1-to-5 star ratings for health inspections, staffing and quality of care. 'Abuse' marks homes CMS cited for abuse recently; 'Special Focus' homes have a long record of serious problems. Ratings change monthly: open Care Compare for the full inspection reports before choosing a home.
Source: U.S. Centers for Medicare & Medicaid Services, Nursing Home Provider Information and Penalties (September 2026)
Why we trust it: Fines for every home (14,690 of 14,690, $454,984,026 in all) match CMS's separate penalties file exactly. 99.9% of homes sit inside their own state; the rest are border towns.

Drug overdose deaths by county
Deaths from drug poisoning of any intent (mostly accidental; fentanyl and other opioids, meth, cocaine and others), counted in the county where the person lived, from death certificates. 2025 figures are provisional: a few records were still under investigation. Overdose deaths fell sharply after 2022-2023, so compare the two periods. Need help? Call or text 988, or find treatment at findtreatment.gov or 1-800-662-4357 (free, confidential, 24/7).

Public libraries
Public library buildings and branches from the FY2024 federal library survey (about 16,900; bookmobiles left out).

Why we trust it: 64–77% of libraries in Texas, Ohio and Colorado have a matching library in OpenStreetMap.
Head Start centers
Open Head Start and Early Head Start centers (free early education for families with low incomes). Home-based and family child-care sites are left out because they can be private homes.
Source: U.S. Department of Health and Human Services, Office of Head Start service locations (daily file, October 2026)
Why we trust it: One official source (HHS). It is the program's own list of open centers.
Post offices
Post office locations (about 31,000).
Source: U.S. Geological Survey, National Structures Dataset (Post Offices), October 2026 pull
Why we trust it: 31,003 vs 30,162 post offices in OpenStreetMap (median state ratio 1.05). 61–83% of ours in Texas, Ohio and Colorado have an OpenStreetMap post office within 250 m.
What crime data is on the map?
31 layers: 100 most violent large cities (2025), Safety grade (county/neighborhood), Safety grade, Safety grade by neighborhood, Crime odds (county/police department/neighborhood), Crime odds by county and 25 more.
100 most violent large cities (2025)
City police departments serving 100,000+ residents, ranked by violent crimes (murder, rape, robbery and aggravated assault) per 100,000 residents in 2025. Top 10: 1. Memphis, TN (1,849); 2. Detroit, MI (1,649); 3. Little Rock, AR (1,484); 4. Oakland, CA (1,475); 5. Kansas City, MO (1,370); 6. Cleveland, OH (1,360); 7. Baltimore, MD (1,346); 8. Peoria, IL (1,250); 9. Birmingham, AL (1,236); 10. St. Louis, MO (1,224). Rates count crimes reported to police, so a city that draws many commuters or visitors looks worse per resident. Not ranked because their police did not report a full 2025 to the FBI: Gainesville, FL, Hollywood, FL, Pompano Beach, FL, Davie, FL, Sunrise, FL, Cape Coral, FL, Orlando, FL, Deltona, FL, Topeka, KS, Baton Rouge, LA, New Orleans, LA, Worcester, MA, Greensboro, NC.
Source: FBI Crime Data Explorer, 2025 crimes reported by each city police department
Why we trust it: Each rate is the department's FBI violent crime count divided by the residents it serves; the same FBI figures as the Crime odds layer, which were spot-checked against the FBI's published agency figures. Ranks are in strict order and every rate recomputes from its count.

Safety grade (county/neighborhood)
Safety score from 0 (least safe) to 100 (safest), by county, with neighborhoods drawn on top where city police data allows. Zoom in to see neighborhoods.
Source: FBI Crime Data Explorer, 2025 (offences by agency and NIBRS incident files for domestic violence); U.S. Census Bureau population; City police incident records, 2025 (each city's open-data portal); FBI 2025 counts for the check; U.S. Census Bureau ACS 2020-2024 neighbourhood population
Safety grade
Each county graded from Least safe to Safest. The grade combines violent crime (60%) and property crime (40%) reported to police in 2025, per resident, compared with the whole country: Each area gets a safety score from 0 (least safe) to 100 (safest): a score of 70 means less reported crime than where 70% of Americans live. Least safe is 0-20, Less safe 21-40, Average 41-60, Safer 61-80, Safest 81-100. It is based on reported crime only (about 4 in 10 violent crimes are never reported), and downtown, shopping and stadium areas grade worse because visitors aren't counted as residents. Race and other population traits are not used. Counties with too little police reporting are not graded.
Source: FBI Crime Data Explorer, 2025 (offences by agency and NIBRS incident files for domestic violence); U.S. Census Bureau population
Why we trust it: Uses the same FBI 2025 figures as “Crime odds by county”, which match the FBI's and California DOJ's published tables.
Safety grade by neighborhood
Each neighbourhood (census tract) graded from Least safe to Safest on the same national scale as counties and police departments, so a Safer neighbourhood in one city means the same as in another. The grade combines violent crime (60%) and property crime (40%) reported to police in 2025, per resident, compared with the whole country: Each area gets a safety score from 0 (least safe) to 100 (safest): a score of 70 means less reported crime than where 70% of Americans live. Least safe is 0-20, Less safe 21-40, Average 41-60, Safer 61-80, Safest 81-100. It is based on reported crime only (about 4 in 10 violent crimes are never reported), and downtown, shopping and stadium areas grade worse because visitors aren't counted as residents. Race and other population traits are not used. Cities whose crime records don't line up with the FBI's (including Chicago, Boston, Seattle and Washington DC) neighbourhoods with under 1,000 residents, and neighbourhoods containing a prison or jail are not graded.
Source: City police incident records, 2025 (each city's open-data portal); FBI 2025 counts for the check; U.S. Census Bureau ACS 2020-2024 neighbourhood population
Why we trust it: Each city's 2025 total for each crime type was compared with its FBI count; any type where the city total is under two-thirds or over 1.5 times the FBI count is not shown for that city. Chicago robbery and car-theft totals match the police department's FBI-coded figures.

Crime odds by county
Your yearly chance of being a victim, as “1 in N residents”, for 8 kinds of crime, with how each county ranks against all U.S. residents (percentile: 90th means higher than places where 90% of Americans live). Shading is the violent-crime percentile. Domestic violence counts victims whose offender was a partner or family member. Odds are left out where police agencies covering under 75% of residents reported, where fewer than 1,000 people live, or where under 10 crimes were reported; the counts still show. Crimes against visitors and commuters are counted where they happen, so business and tourist areas can look higher than the risk to residents.
Source: FBI Crime Data Explorer, 2025 (offences by agency and NIBRS incident files for domestic violence); U.S. Census Bureau population
Why we trust it: Built from the FBIs 2025 crime data by police agency, summed to counties. Chicago, Houston, Phoenix, Denver and Seattle match the FBIs published table exactly; Los Angeles, Sacramento and Fresno counties match California DOJ within 0.6%.
Crime odds by police department
One dot per police department or sheriff, at the location the FBI lists for it. Each popup gives crimes reported in 2025 as “1 in N residents a year”, and how the rate ranks: the 70th percentile means 70% of Americans live where the rate is lower. Darker dots rank higher for violent crime; grey dots have too few reports for odds. These are reported crimes per resident, not anyone's personal risk: about 4 in 10 violent crimes are never reported, and shopping and resort towns look high because visitors aren't residents.
Source: FBI Crime Data Explorer, 2025 (offences by agency; NIBRS incident files for domestic violence)
Why we trust it: Same FBI 2025 agency figures as the county layer, which matches the FBI's published tables and California DOJ within 0.6%.
Crime odds by neighbourhood
Crimes recorded by police in 2025 in each neighbourhood (census tract), as “1 in N residents a year”, and how the neighbourhood ranks within its own city: the 70th percentile means 70% of the city's residents live where the rate is lower. Shaded by violent crime; cities whose violent-crime records don't line up with the FBI's (including Chicago, Boston, Dallas, Denver, Seattle and Washington DC) are outlined but not shaded, and their other crime types are still in the popup. Downtown, airport and stadium areas look high because visitors aren't residents. Domestic violence is never shown by neighbourhood. Counts of 1 or 2 show “fewer than 3”.
Source: City police incident records, 2025 (each city's open-data portal); FBI 2025 counts for the check; U.S. Census Bureau ACS 2020-2024 neighbourhood population
Why we trust it: Each city's 2025 total for each crime type was compared with its FBI count; any type where the city total is under two-thirds or over 1.5 times the FBI count is not shown for that city. Chicago robbery and car-theft totals match the police department's FBI-coded figures.

Violent crimes per year by county
Most crime never reaches the police, so these numbers are a floor, not the full count. In 2024 only about half of violent crimes (48%) and fewer than 1 in 4 rapes and sexual assaults (24%) were reported to police (U.S. Justice Department, National Crime Victimization Survey, Criminal Victimization 2024). A low number does not mean an area is safe. FBI-reported offenses for 2021 to 2025 combined: the average per year from every city police department and sheriff in the county. Each agency counts only the years it reported all 12 months; incomplete years (such as many large cities in 2021, when the FBI changed reporting systems) are left out. Agencies covering several counties are counted in the county where their city is. Faded counties: under 60% of residents covered (under 30%: counts are partial, see the popup note). Unshaded: no police agency there reported a full year. Counts reflect reported crime only (about half of violent crime is never reported). Shading is the raw count, so bigger counties are usually darker; the popup also gives the rate per 100,000. Where the FBI file leaves a county empty or thin, official state figures fill it (New York DCJS for the five NYC boroughs, Georgia GBI, Puerto Rico Police); the popup names the source.
Source: FBI Uniform Crime Reporting 2021-2025 (agency level, Return A), averaged and summed by county by Map the Block; Census population
Why we trust it: County totals add up to 91.2% of all FBI-reported violent crime (the rest is state police and campus agencies, which have no resident population); multi-county agencies placed by their city's location.

Homicide deaths by county (CDC death records)
Deaths ruled homicides on death certificates (U.S. CDC, National Center for Health Statistics), per year on average for 2016-2022, by the county where the person lived. A coroner or medical examiner rules every death, so this count does not depend on how police classify a case. Compare it with murders reported by police (FBI, 2021-2025): the years differ, and homicides peaked in 2020-2022, so small differences are expected; a large, lasting gap is worth asking your police department about. The CDC does not publish counties with fewer than 10 homicide deaths in the 7 years, and has no county figures for Puerto Rico.
Source: U.S. CDC National Center for Health Statistics (National Vital Statistics System) mortality files, as published by County Health Rankings & Roadmaps 2025 (University of Wisconsin Population Health Institute)
Why we trust it: Philadelphia: 411 a year here vs 411 from the city's own yearly homicide counts for 2016-2022. National sum of published counties (20,671 a year) is about 95% of the CDC national total, the rest being small counties the CDC does not publish.

Figures are the average per year for 2021 to 2025, using only the years the agency reported all 12 months (the popup lists them and the yearly counts; n/r = not a full year). Colours show the raw yearly count; the popup also gives the rate per 100,000 residents of the agency's area. Sheriffs usually cover only unincorporated areas. City police dots sit at the Census center point of their city; others at the FBI's reference point. Dots mark the agency, not where crimes happened. Where an agency recorded murder motives, the popup also shows how many 2025 murders police classified as gang-motivated (FBI homicide reports). Most agencies leave the motive blank, so these are minimum counts and are missing for most places.

State and federal prisons
How many people each prison holds, from each agency's own latest report: the Bureau of Prisons weekly, states monthly to yearly. Bigger circle = more people. Florida, Texas, West Virginia, Missouri, New Mexico and Arizona don't publish counts per prison, so those show capacity. Some states report monthly averages instead of a single day. No individual records are shown.
Source: Federal Bureau of Prisons; each state's Department of Corrections population reports (dates in each popup); locations from agency addresses (U.S. Census geocoder) and OpenStreetMap
Why we trust it: Federal and California counts add up exactly to their published totals, and 36 of 39 states that publish both facility counts and a total match within 1% (the rest are explained gaps such as contract beds). 92% of state prison locations are confirmed by a mapped prison within 3 km.

Registered sex offenders (by area)
How many people on the official sex offender registry list a home address in each area: about 1 mile across when zoomed out, and 1/8 mile across (about two blocks) when you zoom in to street level. No names or addresses are shown; areas with 1 or 2 show “fewer than 3”, and areas containing a prison or jail are left out. Shown where the official registry data may be reused: DC, Florida (released or supervised, living in Florida), Georgia, Missouri (active registrants), North Carolina, Tennessee (active registrants living in the state), Texas (registrants whose current address is a Texas home; not those in prison, transient, absconded or living elsewhere) and the City of Chicago, plus county map services for Faulkner County AR, Frederick County MD, Trumbull County OH, Skagit County WA (Level II and III only) and Natrona County WY. For anywhere else, and to look up a person, use the official national search (Sex offender registry link). Florida updates daily; Texas is as of October 7, 2026.

Registered sex offenders (by county)
Number of registered sex offenders listed in each county, from each state’s own published county counts (the popup gives the date and the rate per 10,000 residents). Iowa (August 2022) and Maryland (2020) are the latest county counts those states have published; Florida is from an October 2024 state audit report. What is counted differs a little by state (for example, some include people in jail). Other states don’t publish county counts in a form we may reuse. Texas counts registrants whose current address is a Texas home (October 7, 2026). Minnesota counts registrants living in the community (a home, homeless, or a residential facility; not prison or the state's secure treatment hospitals at Moose Lake and St. Peter), as of October 2026. Florida updates daily.

Most wanted (official lists)
People on official most-wanted lists, updated every day; anyone the agency marks captured comes off the map. Each dot is the last-known city or county on the official poster, never an address. Many federal fugitives are believed to be abroad and are not on the map. Do not approach: call 911 or the number on the poster. Positive identification is up to law enforcement.

Mass shootings (1900-2026)
Each dot is one shooting where 4 or more people were shot (not counting the shooter), or 4 or more killed. Trackers define mass shootings differently, so 'Counts as' shows which definitions it meets. Shootings at homes, and Gun Violence Archive locations, are placed at about 1 km, never an exact address. No names are shown.

Gang-related murders (by state & police agency)
Each department decides what counts as gang-related. A blank or low number can mean the department rarely records it, not that there is none. Counts of 1 or 2 show as 'fewer than 3'. Don't compare places. Police often record no motive at all, and the popup shows how often. Police reports undercount gang violence because motive often isn't recorded; each popup also shows an independent estimate from CDC death records (NVDRS) and local research, as a range. Shading uses the reported counts.

Why we trust it: FBI national total 296 vs FBI's own Table 12 294; California 181 vs CA DOJ 190; LAPD 2021-23 within 1% of LAPD year-end counts. FBI counts run 0-60% of what departments that track gang crime announce, so they are a minimum.

Gang-related homicides by state
Each department decides what counts as gang-related. A blank or low number can mean the department rarely records it, not that there is none. Counts of 1 or 2 show as 'fewer than 3'. Don't compare places. Shaded by the state's own report where it is from 2023 or later (CA, VA, MD, SC, CT, KS); otherwise by FBI homicide reports, which are a minimum. Police reports undercount gang violence because motive often isn't recorded; each popup also shows an independent estimate from CDC death records (NVDRS) and local research, as a range. Shading uses the reported counts.

Gang-related murders by police agency
Each department decides what counts as gang-related. A blank or low number can mean the department rarely records it, not that there is none. Counts of 1 or 2 show as 'fewer than 3'. Don't compare places. Dots mark the police agency, not where crimes happened.

Gang-flagged violence (Los Angeles County)
Violent incidents (homicide, shooting, aggravated assault, robbery) that LAPD or the Sheriff marked gang-related, counted into areas about ¾ mile across. Areas with 1 or 2 show 'fewer than 3'. No exact location is shown. Each department decides what counts as gang-related. LAPD changed record systems in March 2024, so 2024 is partial and later years are minimums.
Source: LAPD open data (gang-related flag and MO codes) and LA County Sheriff Part I & II crimes (GANG_RELATED flag)
Why we trust it: LAPD 2021-2023 gang homicides within 1% of LAPD's year-end counts; LASD 2025 within 15% of FBI homicide reports for LASD and its contract cities.

Gang violence in the 200 most violent cities
Each department decides what counts as gang-related, and most big departments publish nothing. A blank, 0 or low number usually means the motive was not recorded or not published, not that there is none. Definitions differ (motive, gang member involved, group member involved), so don't compare cities. Shading covers the whole city, not where crimes happened. Police reports undercount gang violence because motive often isn't recorded; each popup also shows an independent estimate from CDC death records (NVDRS) and local research, as a range. Shading uses the reported counts.
Source: Police annual reports and year-end releases, city violence-reduction reports, NICJR/NNSC problem analyses, California DOJ homicide file, police open data (LA, Dallas, Tacoma, LA County Sheriff), FBI Supplementary Homicide Reports 2025 (cited per city)
Why we trust it: 136 cross-checks across the 200 cities: 48 match, 7 close; the rest compare against state/FBI motive coding, which captures only part of a department's own count. CA DOJ statewide 189 vs Table 21 190; LAPD 2021 231 vs 232. City ranks 101-200 match the FBI's Table 8 violent-crime counts exactly.

What places are on the map?
7 layers: Bars and nightlife, LGBTQ+ Degenerate bars & clubs, Gun shops, Gun dealers without a storefront (½-mile area), Liquor stores, Planned Parenthood Baby Killing Health Centers and 1 more.
Bars and nightlife
Bars, pubs, nightclubs and beer gardens mapped in OpenStreetMap: about 40,900 nationwide. Dense areas are thinned when zoomed out; zoom in to see every place. Places open and close often, so check before you go.
Source: © OpenStreetMap contributors (ODbL); checked against the U.S. Census Bureau's County Business Patterns 2023 count of drinking places
Why we trust it: Nationwide, 40,625 mapped bars vs 41,236 drinking-place businesses counted by the Census Bureau (99%). State by state it varies (0.4x to 6.7x) because states license and classify bars differently.
LGBTQ+ Degenerate bars & clubs
Bars, clubs and other venues that OpenStreetMap mappers list as mainly or only for LGBTQ+ people: 394 places. This is incomplete: a 2023 study counted about 830 gay and lesbian bars nationwide, so a missing place usually just hasn't been listed yet.
Source: © OpenStreetMap contributors (ODbL), venues tagged lgbtq=primary or only; total compared with Mattson (2023), Socius
Why we trust it: One source (OpenStreetMap). Its total is about 47% of the national count in a 2023 study (Mattson, Socius), so many venues are missing.
Gun shops
Only licence types 01 (dealers and gunsmiths) and 02 (pawnbrokers) with evidence of a public storefront: a shop mapped in OpenStreetMap or listed as a store in Overture Maps, the shop's own website showing its address or phone, or a known retail chain. Every other dealer licence, including home-based dealers that trade under a business name, appears only as a count in a ½-mile area in the "Gun dealers without a storefront" layer. Collectors, manufacturers and importers are left out. Holders' personal names are never shown. Phone numbers are shown only for shops confirmed as storefronts in OpenStreetMap or Overture Maps. Each hours, phone and website row says where it came from (OpenStreetMap, Overture Maps or the shop's own website). Call before you go.

Why we trust it: Since 17 October 2026 a licence is shown as a point only with evidence of a public storefront: a matching OpenStreetMap shop (3,804), a matching Overture Maps retail place (10,873; a place known only from a Facebook page counts only outside gun-store listings and residential-looking streets), the shop's own website showing its phone or street (4,468), a known retail chain (4,637), or a gun shop found only in OpenStreetMap (614). 30 of 30 sampled points carry that evidence; 30 sampled withheld licences showed no clear storefront in the same data. 25 of 25 sampled shops match their ATF listing row exactly (name, address, licence type). Geocoded ATF shops sit a median 152 m from the matching OpenStreetMap shop; 99.9% sit inside their own state. The 13 monthly ATF files on hand are consistent. Websites and phones added from Overture Maps were matched by name within 300 m (or the same phone within 2 km), and each website was kept only if the shop's own page shows its phone, street or ZIP, or its domain names the shop: 25 of 25 sampled added websites belong to the same business. 21 of 25 sampled hours taken from shops' own websites match the page exactly; the other 4 were site-builder defaults, which are now left out.

Gun dealers without a storefront (½-mile area)
Many of these licences are run from a home, so no point, address, name, licence number or phone is ever shown: each licence is counted in an H3 hexagon about ½ mile across. Shading is the raw number of licences in the area. Collectors, manufacturers and importers are not included.
Source: Exact addresses withheld for privacy (½-mile area). Source: ATF Federal Firearms Licensee list, Sept 2026
Why we trust it: The 36,898 licences covered are every type 01/02 licence on the September 2026 ATF list that is not a storefront point in Gun shops (a second licence at the same address under the same name counts once). Hexagon counts add up to the 32,440 placed licences; the publish gate refuses the file if any feature holds anything besides the area id, count, licence types and source.

Liquor stores
Stores that sell spirits to take home. Where a state's licence class also covers groceries, convenience stores, gas stations and drugstores (CA, FL, WA, MO, NE, ND, WY, DE, IL, MA, KY, AZ), a licence is kept only when its name says liquor, spirits, package store and the like, it is a known liquor chain, or OpenStreetMap or Overture shows a liquor store there. Beer and wine shops, bars and grocery stores are not included. In PA, NC, VA, NH, VT, ME, OH, ID, UT and MT spirits are sold only in state or agency stores, so only those are shown, and many agency stores inside other shops are missing (Ohio, Maine, Vermont). Licence holders' personal names are never shown. Stores marked approximate are at the centre of their ZIP or city (rural-route addresses the geocoder cannot place).
Source: State licence lists (official open data / public records): NY State Liquor Authority; Texas ABC; California ABC; Florida DBPR Alcoholic Beverages & Tobacco; Colorado Liquor Enforcement; Connecticut DCP; Oregon OLCC; Washington LCB; Missouri ATC (data.mo.gov); Oklahoma ABLE; North Dakota Attorney General; Nebraska LCC; Wyoming Liquor Division; Montana DOR; Delaware Division of Revenue; DC ABCA; Alabama ABC Board; Utah DABS (UGRC); City of Chicago; City of Boston; Baltimore City Liquor Board; Anne Arundel County; Louisville Metro (KY ABC); City of Tucson GIS (AZ DLLC). OpenStreetMap contributors (ODbL) and Overture Maps Foundation Places (CDLA-Permissive-2.0), both non-official
Why we trust it: 25 of 25 sampled stores in NY, TX, CO, CT and OR are still listed at the same address on the state portal, and 113 of 114 sampled stores from the 18 newer official lists match a second lookup at their source. Overture-only stores: 46 of 183 checked on their own websites show the same address or phone (most others are chain or app pages with no address); Overture stores are not added in VA, NH and ME, where none could be confirmed. Totals vs the Census 2023 count are within 0.5-1.6x in 46 states and DC; low in PA 0.38, OH 0.23 and ME 0.08 (only state or agency stores sell spirits there, and Census also counts beer and wine shops), high in UT 2.18 (Census leaves out state-run stores).

Planned Parenthood Baby Killing Health Centers
In-person Planned Parenthood health centers, with each center's own name and address only. School-based sites (students only), offices, labs, pharmacies and centers no longer listed by Planned Parenthood are left out. Hours and websites come from OpenStreetMap and are missing for most centers. Services differ by center and by state law, so call or check online before you go.
Source: U.S. Department of Health and Human Services, Office of Population Affairs, Title X Family Planning Directory (August 2026); Centers for Medicare & Medicaid Services, NPPES provider registry (October 2026) (both official); OpenStreetMap contributors (ODbL, non-official) for hours, websites and positions
Why we trust it: 21 of 25 sampled centers match an active Planned Parenthood practice address in the live CMS NPPES registry; 3 others are Title X directory sites with no registry entry in that ZIP, and 1 has a different registry address. Every center shown matches one of the in-person centers Planned Parenthood itself lists, by ZIP or city (virtual, mail-order and online-only pages left out).

Abortion laws by state
State abortion law as of 2026-10-16: the gestational limit now enforced, its exceptions and penalties, with the statute. Where a stricter ban is blocked by a court but a lesser limit is enforced, the state is shaded by the enforced limit and the blocked ban is described in the popup. Yearly counts are abortions by the state where they happened (not where the patient lives): CDC Abortion Surveillance 2013-2022 (the newest CDC year published); a few states do not report to CDC, so those years come from the Guttmacher Institute's Abortion Provider Census when it published a figure for that year, labelled non-official, and are left blank otherwise (never estimated). Years after the newest CDC year are Guttmacher Institute Monthly Abortion Provision Study estimates (non-official, rounded to 10); they count telehealth abortions in the state where the pills were received, including those prescribed from other states, which is why some states with bans show counts. Not legal advice.
Source: State statutes; CDC Abortion Surveillance; gaps and 2023-2025 from Guttmacher Institute (non-official)
Why we trust it: Law as of 2026-10-16, drafted from statute text on official legislature code sites (or the enacted bill/act PDF, court notices and official ballot pages) for 46 of 51 jurisdictions. CA, DC, IN, OK and TN official code hosts refuse or block us, so those rest on official secondary pages (CA Legislative Analyst, OK Attorney General memo) plus KFF/Guttmacher/CRR cross-checks. 327 quoted checks were re-matched by script against the saved pages (308 matched exactly or letter-for-letter; the rest are summaries of cross-check tables), and the operative limit was read by hand in the statute or ruling for 17 states. Every state was compared with KFF, Guttmacher or the Center for Reproductive Rights: 12 differences remain and are explained in the popups (e.g. WY, where KFF still lists a 6-week limit that a court blocked on 2026-04-24). Counts: every CDC year 2013-2022 adds up to CDC's stated national total (2014 off by 1 inside CDC's own table); 30 random CDC rows, all 23 Guttmacher gap-fill rows and all 153 Guttmacher 2023-2025 rows were re-read from the source tables and match. 16 state-years (CA, MD, NH 2015/2018/2021/2022; NJ 2021-2022; WY 2015, 2018) are left blank because no reliable source states a figure.

What religion data is on the map?
18 layers: All faiths (by area), Places of worship (by county/area), Places of worship (by county), Religious adherents by county (all faiths), Catholic adherents by county, Evangelical Protestant adherents by county and 12 more.
All faiths (by area)
How many places of worship (all faiths, one category) are in each hexagon area: about ⅔ mile across zoomed out, about 3 blocks zoomed in. Individual buildings are never shown; areas with only 1 or 2 show as “fewer than 3”. Darker = more places.
Source: © OpenStreetMap contributors (ODbL); checked against IRS Exempt Organizations records geocoded by U.S. EPA/HIFLD
Why we trust it: Compared state by state with federal IRS records of religious organizations (all 50 states; national totals within 6%).
Places of worship (by county/area)
Places of worship of all faiths, shaded by county, with small areas on top as you zoom in.

Places of worship (by county)
How many places of worship (all faiths) are mapped in each county. The popup also shows the rate per 10,000 residents and how the places divide by faith. Shares are of buildings, not of people, and OpenStreetMap misses some places, especially for smaller faiths.
Source: © OpenStreetMap contributors (ODbL); U.S. Census Bureau County Business Patterns 2023 (religious organizations, NAICS 813110); Census population
Why we trust it: Compared county by county with the Census Bureau's count of religious organizations: OpenStreetMap usually lists more (median 1.44×) because the Census only counts congregations with paid staff (e.g. Latter-day Saint wards are missing from it). The national total is also checked against IRS records.
Religious adherents by county (all faiths)
Adherents are members, their children and regular attenders reported by each congregation in 2020 (the U.S. Religion Census), counted where they worship. Groups that don't report are missing, so Mainline and especially Black Protestant churches are undercounted, and Latter-day Saints run about 4% low in the Mountain West. Shading is the number of adherents; the popup adds congregations, shares, and PRRI's survey estimate of how adults describe themselves.

Why we trust it: Same Religion Census file and checks as the other faith layers.
No religion (estimated adults, PRRI)
Estimated number of adults who describe themselves as having no religion (atheist, agnostic or nothing in particular), from PRRI's county survey model applied to each county's adults. These are model estimates, not head counts; PRRI's county model gives a lower national share (23%) than its national survey (about 27%), so treat county figures as approximate. Faith groups are combined by religion only.

AMBER Alerts (live)
Counties covered by an AMBER Alert issued right now. Checked every 2 minutes; alerts disappear when they end. If you see the child, suspect or vehicle, call 911 immediately.
Source: National Weather Service alerts API (Child Abduction Emergency), relaying alerts issued by state AMBER Alert coordinators
Why we trust it: Official live feed from the National Weather Service; alerts are shown as issued.
Missing children (open cases)
Children under 18 (on the day they went missing) who are still listed as missing today by the FBI and by the Texas, Florida, New York and California clearinghouses, including older cases. Each dot is the city or county on the poster, never an address; children from the same place are spread out a little so each can be clicked. Updated every day: a child the agency marks found comes off the map. Other states and NCMEC's national list are not included yet. If you see a missing child, call 911 now. Tips: 1-800-THE-LOST (1-800-843-5678).
Source: FBI; Texas DPS Missing Persons Clearinghouse; Florida FDLE Missing Endangered Persons Information Clearinghouse; New York DCJS Missing Persons Clearinghouse; California Department of Justice
Why we trust it: Every source's count is matched against its own published total on each run (a mismatch stops that source); 10 random cases were checked against their live posters and all 10 matched.
Missing persons (national databases)

Traffic deaths (2024, by county)
People killed in traffic crashes in 2024 by county (the popup also gives the rate per 100,000 residents) (federal FARS records). Counties with 1 or 2 deaths show “fewer than 3” and no rate; crash locations are never shown. One year can swing a lot in small counties.
Source: NHTSA Fatality Analysis Reporting System (FARS) 2024; Census population
Why we trust it: State totals compared with the states' own counts: Ohio matches exactly (1,157), Texas within 0.3% of TxDOT, Florida within 1.3%.

Why we trust it: Station counts match the U.S. Fire Administration's National Fire Department Registry: 51,976 vs 52,572 nationwide, and the middle state is within 1%. 84–89% of OpenStreetMap fire stations in Texas, Ohio and Colorado have one of ours within 250 m.
Police & sheriff stations
Police stations, sheriff's offices and substations (about 18,200). Some small departments that work out of a town hall may be missing. Call 911 in an emergency.

Encampment reports to 311 (cities)
How many times people reported a homeless encampment to the city's 311 / service-request line from inside each area about 1 mile across, per year. These are REPORTS, not people and not camps: one camp can get hundreds of reports, many get none, and reporting habits differ a lot between neighborhoods and cities, so compare areas within one city, not across cities. Areas with 1 or 2 reports show as “fewer than 3”. No individual location is shown.
Source: City open-data portals: MyLA311 (CC0), SF 311 (PDDL), OAK 311, San Jose 311 (CC0), San Diego Get It Done (PDDL), Sacramento 311 Calls View, Seattle Unauthorized Encampment Reports, Portland Impact Reduction Program Campsite Reports, NYC 311, Dallas 311 (PDDL), KCMO 311, Philadelphia 311
Why we trust it: Every city's download matched the city server's own count (Sacramento 2026: +2 reports that arrived during the download). Seattle's 2025 total (76,790) is within 0.05% of the 76,756 in the City's 2025 Q4 encampment report to Council; Portland's weekly totals are within 1% of the City's Weekly Street Services reports; Sacramento's requests match the City's published weekly 311 call counts (740 = 740 for Sep 1-7 2025).

What riots/protests data is on the map?
5 layers: All protests and riots, 2017-2026 (by place), Campus protests, 2017-2026 (by college), Riots damage in dollars, George Floyd Riots, 2020 (by place), Protests and Riots against ICE, 2017-2026 (by place).
All protests and riots, 2017-2026 (by place)
Every in-person protest, march, rally, vigil or riot the Crowd Counting Consortium logged from news and social media, one dot per city or town. Arrests and injuries are 'at least' figures (many reports give no number). 'Damage and costs in dollars' appears where an official or news source published a figure. 2016 is not included: the consortium started in 2017.
Source: Crowd Counting Consortium (Harvard Kennedy School and University of Connecticut), protest events 2017-2026; dollar figures from published official and news sources (see Riots damage in dollars)
Why we trust it: Every event with a location is placed; 212 places the consortium filed under the wrong state (e.g. Minneapolis, MI) were moved to the state their map point is in. Arrests, injuries and damage are totals of what news reports gave, so they are minimums.

Campus protests, 2017-2026 (by college)
Protests held on or at a college or university campus, including the 2024 Gaza encampments. Arrests are 'at least' figures from news reports. A campus is listed when at least 2 events name it.
Source: Crowd Counting Consortium (Harvard Kennedy School and University of Connecticut), protest events 2017-2026; dollar figures from published official and news sources (see Riots damage in dollars)
Why we trust it: Arrest totals were checked against official and news counts for the largest 2024 encampments: every campus is at or above the sourced single-event figure (Columbia 322 vs 108 + 112 + 80; City College 173 vs 170; Cal Poly Humboldt 35 vs 32; Indiana 58 vs 57; UC Irvine 47 vs 47; Stanford 13 vs 13). National tallies for spring 2024 were about 3,100 arrests (AP, New York Times).
Riots damage in dollars
Dollar figures for protests and unrest, one marker per protest and place; bigger markers mean larger figures. Each popup lists every figure found and what it counts: property damage, insured losses, the cost of the police or troop response, or legal settlements. These are different things and are never added up. The 2020 protests caused an estimated $1 to $2 billion or more in insured losses nationwide (Property Claim Services), the largest on record. Places with no published dollar figure are not shown here.
Source: City, state and federal reports, insurers (Property Claim Services, Insurance Information Institute), courts and news reports quoting them
Why we trust it: Each figure is labelled with who published it, and most were confirmed by a second source. Figures are never added together because they count different things.
George Floyd Riots, 2020 (by place)
One marker per city or town: how many protests were recorded there in 2020 after George Floyd's killing, and how many had property damage, arson or clashes reported. Bigger markers mean more protests; darker markers mean more events with damage. Most protests had no damage reported. Arrest and injury numbers are minimums, since many reports give no number. Dollar figures are in the “Protest damage in dollars” layer.
Source: Crowd Counting Consortium (Harvard Kennedy School Ash Center and University of Connecticut); Count Love (CC BY 4.0); Wikipedia contributors (CC BY-SA 4.0)
Why we trust it: Matches the Crowd Counting Consortium's own published totals (peak day June 6: 731 events in 624 places vs “over 700 in over 600”; about 96% of events with no damage reported). 16 events hand-checked against news reports.
Protests and Riots against ICE, 2017-2026 (by place)
One marker per city or town: how many protests mainly against ICE or immigration enforcement were recorded there, the date range, and how many had property damage, arson or clashes reported. Bigger markers mean more protests; darker markers mean more events with damage. Arrest and injury numbers are minimums. Data runs to May 31, 2026. Dollar figures are in the “Protest damage in dollars” layer.
Source: Crowd Counting Consortium (Harvard Kennedy School Ash Center and University of Connecticut)

What environmental and hazard data is on the map?
17 layers: Natural hazard risk (FEMA), Flood risk, Wildfire risk, Tornado risk, Extreme heat risk, Hurricane risk and 11 more.
Natural hazard risk (FEMA)
FEMA's National Risk Index: expected yearly losses from 18 natural hazards, adjusted for how vulnerable and resilient each county is. Scores rank counties against each other (higher = more risk). It's a modelled long-run estimate, not a prediction, and it rates poorer places higher because they're more vulnerable.
Source: FEMA National Risk Index v1.20 (December 2025), county scores
Why we trust it: FEMA's recorded tornado events for Oklahoma, Kansas and Alabama compared with NOAA storm records (moderate agreement, as expected for a long-run model). FEMA's scores are modelled estimates, so this layer is labelled single source.

Superfund cleanup sites
Sites on EPA's National Priorities List (final) or proposed for it, where EPA is managing a long-term cleanup. Being listed means EPA is handling the cleanup; it doesn't by itself mean people are exposed today. Each dot is the centre of EPA's mapped site boundary.
Source: U.S. EPA, Superfund site boundaries and NPL status (October 2026)
Why we trust it: 1,321 final sites mapped = 98% of the 1,343 EPA lists on its NPL summary page (August 2026); 36 proposed vs EPA's 37. 99.5% of dots fall inside the state EPA lists for the site.
Open “Superfund cleanup sites” on the map → · Superfund Sites Map: Every EPA Cleanup Site →
Superfund sites with cleanup completed
Former National Priorities List sites that EPA has deleted from the list because it considers the cleanup complete. Some still have long-term monitoring or limits on how the land can be used.
Source: U.S. EPA, Superfund site boundaries and NPL status (October 2026)
Why we trust it: Same EPA file as the active Superfund layer, which is checked against EPA's published NPL totals.
Industrial chemical releases (TRI 2024)
Facilities that reported releases of listed chemicals to EPA's Toxics Release Inventory for 2024: total pounds released on site (air, water, land) and sent off site for disposal. These are amounts the companies reported, mostly under permits, not a measure of health risk. Mines report the most pounds, mostly as waste rock on their own land.
Source: U.S. EPA Toxics Release Inventory, reporting year 2024 (basic data file)
Why we trust it: Kentucky: 405 facilities vs 404 in Kentucky's own 2024 TRI report, and the two facilities checked (North American Stainless, Phoenix Paper Wickliffe) match to the pound. National total 3.29 billion lb from 21,482 facilities vs EPA's latest National Analysis (2023): 3.3 billion lb, 21,000+ facilities.
Unhealthy air days (2024)
Number of days in 2024 when the county's Air Quality Index was above 100 (unhealthy for sensitive groups or worse), from EPA's air monitors. The popup adds EPA's official 3-year design values for fine particles and ozone. Counties without a monitor are left grey, not counted as clean.
Source: U.S. EPA AirData, annual AQI by county 2024; EPA Air Quality Design Values 2023-2025 (June 2026)
Why we trust it: Compared with EPA's separate 2023-2025 ozone design values: counties with more unhealthy days have higher ozone values (rank correlation 0.63 over 574 counties), and 99% of the 96 counties over the ozone standard had at least one unhealthy day in 2024.

Drinking-water health violations
How many community water systems in the county have a current health-based violation in EPA's records: a contaminant over its legal limit, or a required treatment step not done. Missed paperwork isn't counted. A system serving several counties is counted in its main county. Your utility's yearly water-quality report has the details.
Source: U.S. EPA SDWIS via ECHO drinking-water download (September 30, 2026)
Why we trust it: Texas county totals add up to 4,749 active community water systems vs 4,747 in the Texas Commission on Environmental Quality's 2025 compliance report (0.04% apart).

Radon potential (EPA zones)
EPA's county radon zones from its 1993 map: Zone 1 counties have the highest predicted average indoor radon. Any home can have high radon, whatever the zone; the only way to know is to test.
Source: U.S. EPA Map of Radon Zones (county list re-posted June 2024)
Why we trust it: All 99 Iowa counties are Zone 1, as Iowa's health department says; zone totals (1,074 / 1,032 / 1,038) are within 0.2% of EPA's list after matching names to today's counties.

Lead paint risk (homes built before 1950)
How many homes (houses and apartments) were built before 1950, and their share of all homes. Paint from before 1950 is the most likely to contain lead, and lead paint was banned for homes in 1978, so older homes are the main source of lead poisoning in children. This shows risk, not test results: many older homes have been fixed up. Children under 6 in an older home should get a blood lead test (ask a doctor or the local health department). Neighbourhood figures are survey estimates; faded areas have a wide margin of error.
Source: U.S. Census Bureau, American Community Survey 2020-2024 5-year, table B25034 (year structure built)
Why we trust it: Matches the Census Bureau's own published shares of homes built before 1950 (table DP04) to within 0.15 point in all 3,222 counties and all 11,560 neighbourhoods checked in Michigan, New York and Pennsylvania.

Bridges in poor condition
Highway bridges whose deck, beams, piers or culvert were rated 4 (poor) or worse at their last inspection. Poor does not mean unsafe to drive over today: bridges that are unsafe are closed or given a weight limit, shown under Status. Most bridges are inspected every 2 years. Darker dots carry more traffic.
Source: U.S. Federal Highway Administration, National Bridge Inventory 2025 (state bridge inspections)
Why we trust it: Exactly matches FHWA's published 2025 condition table: 41,685 poor bridges out of 624,193 nationally, and the same counts for Iowa (4,423), Pennsylvania (2,813) and Illinois (2,563). 99.8% sit inside their own state; the rest cross state-line rivers.

High-hazard dams
High hazard means people downstream would probably die if the dam failed. It is about what lies below the dam, not how likely it is to fail. The condition rating covers repair: Satisfactory (no problems found), Fair (fine in normal weather; a rare flood or earthquake could cause one), Poor (a problem needs more study or repair), Unsatisfactory (a problem needs fixing right away). Many federal dams, such as Hoover Dam, do not publish a rating. Darker dots are in worse condition.
Source: U.S. Army Corps of Engineers, National Inventory of Dams (public map service, October 2026)
Why we trust it: All 16,971 dams the Army Corps counts as high hazard are on the map. 99.7% sit inside their own state; the rest are on state-line rivers. Spot checks match: Oroville Dam 770 ft, Hoover Dam 730 ft, and Michigan's Edenville Dam, which failed in 2020, is rated Unsatisfactory.

Taxes collected by state (FY2025)
Every tax the state government collected in its fiscal year 2025: income, sales, corporate, fuel, tobacco, licenses and the rest. Local taxes (mostly property tax) are not included here; the popup also gives state + local taxes for FY2024. A $0 line means the state does not levy that tax.
Source: U.S. Census Bureau, Annual Survey of State Government Tax Collections (STC), FY2025 (API timeseries/govsstatetax)
Why we trust it: 50-state sum equals Census's US total to the dollar (DC is listed separately); income tax is 33.7% and general sales 30.9% of the total, matching Pew's FY2025 analysis. State checks: NY income tax $61.2B vs the NY Comptroller's $61.2B; CA $128.7B vs the State Controller's $126.6B General Fund figure; Texas sales + vehicle sales tax within 0.6% of the Comptroller.
State + local taxes (FY2024)
All taxes collected by the state government plus every county, city, school district and special district in the state, FY2024. Includes property tax, which is mostly local.
Source: U.S. Census Bureau, Annual Survey of State and Local Government Finances (ALFIN), FY2024 (API timeseries/govslocalfin)
Why we trust it: Every state + DC adds up exactly to Census's US total. State-government federal revenue matches Census's separate State Government Finances release exactly. Police total is 90% of BEA's 2024 national-accounts figure (a broader, calendar-year measure).

Money the federal government paid to the state government and its local governments in FY2024 (Census 'intergovernmental revenue from the federal government'): Medicaid's federal share, highway, school and other grants. It does not include Social Security or other payments to people, or federal contracts; see 'All federal spending in state' for those.

Every federal award obligated in fiscal year 2025 with a place of performance in the state, as reported on USAspending.gov: grants (to governments and others), contracts, and direct payments to people such as Social Security and Medicare. Loans are left out. Contracts are counted where the work is done, which can differ from where the money ends up.
Source: USAspending.gov API, spending_by_geography, place of performance, FY2025 (Oct 2024 - Sep 2025)
Why we trust it: States + DC hold 97% of all FY2025 grant dollars, 95% of contracts and 99% of direct payments; the rest is territories, overseas and awards with no state recorded.

U.S. senators and campaign money
Both U.S. senators for each state, senior senator first. The money period is the six years ending with each senator's last election (for example 2019-2024 for a senator elected in 2024), the same span the FEC shows; appointed senators not yet elected show 2025-26 so far. Shading adds the two senators' totals, so states whose senators faced costly races are darker. Money is what the member's own campaign committees reported to the Federal Election Commission. 'Donors employed by' adds up itemized contributions (generally over $200 a year) from people who wrote that employer on the form; it is not money from the company itself. 'PACs giving the most' are direct contributions from political action committees, including a company's or union's PAC and leadership PACs run by other politicians; party committees are listed separately. Industry totals are not shown: the FEC does not classify donors by industry. Outside spending by super PACs and other groups is not included, except the United Democracy Project rows, which are labelled as spending about the member, not money given to the member. AIPAC rows: Source: FEC filings by AIPAC PAC (C00797670), the federal PAC of the American Israel Public Affairs Committee: Schedule B line 23 contributions to the member's FEC candidate committees, plus United Democracy Project (C00799031) independent expenditures. Earmarked contributions are given by individuals and passed on by AIPAC PAC as a conduit. Two-year cycles 2022, 2024 and 2026 (to the latest FEC data, Oct 2026). Money given to leadership PACs and party committees is not included. Career total: every House and Senate campaign the member has run since 1979-80 (FEC), counting money moved between their own committees once; presidential runs not included. Largest donor: the company or group whose employees and PAC gave the most, 2015-2026 (no individual donors named). Net worth: estimated from each member's financial disclosure ranges (House Clerk; Senate eFD), household including spouse; excludes the primary home (not reported), and open-ended ranges count at their minimum. The earliest figure is the earliest electronically filed report (year shown); a few members file on paper and aren't read.

Why we trust it: Total raised matched FEC's own candidate pages to the dollar for 10 of 10 sampled members (5 senators, 5 representatives, both parties); itemized individual totals within 5% of the same pages. Committee-level and candidate-level FEC totals agree within 1% for 531 members. PAC contributions reported by the PACs come to a median 98% of what members reported receiving. Member list: 100 senators, identical to senate.gov's list.
U.S. House members and campaign money (2024 election)
The member of the U.S. House for each 119th Congress district. Money period: 2023-24 (the 2024 election); members first elected in a 2025-26 special election show 2025-26 so far. Vacant seats are labelled and unshaded. Money is what the member's own campaign committees reported to the Federal Election Commission.

What national/state parks data is on the map?
7 layers: National parks & sites, Park Service land (boundaries), Park Service sites (points), State parks, State park land (boundaries), State parks (points) and 1 more.
National parks & sites
Every National Park Service site: national parks, monuments, historic sites, battlefields, seashores, recreation areas, trails and more. Green shading is Park Service land; click a dot for acres, hours, entrance fee, 2025 visitors and the official nps.gov page. Hours were read from nps.gov in October 2026 and do not include dated seasonal closures or holidays; check the official site before you go.
Source: U.S. National Park Service: unit boundaries (Land Resources Division), Acreage Report (Sept 30, 2026), park pages on nps.gov (hours, fees), Visitor Use Statistics (2025)
Why we trust it: Acres add up to the Park Service's own September 30, 2026 acreage report (85,160,472 of 85,160,480 gross acres; the gap is rounding). 434 units against the 433 the Park Service lists: one historic site or park is counted differently. Spot checks: Yellowstone 2,219,791 acres, Great Smoky Mountains 522,427, Grand Canyon 1,201,647, Thaddeus Kosciuszko (smallest) 0.02.

State parks
States count their park systems differently (some include trails, forests or historic sites), so totals won't match every state's own number exactly. Hours and fees change; check the official site before you go.
Source: USGS Protected Areas Database of the U.S. (PAD-US 4.1); state park agencies' open data (CA, NY, PA, TN, TX, FL, NJ, KY, HI, UT, MT and others); OpenStreetMap contributors for some hours, phones, fees and camping
Why we trust it: Wisconsin trimmed to the DNR's official park list (Ice Age Trail reserve parcels removed); South Dakota parks matched to Game, Fish & Parks' official list. Counts close to the states' own: MN 66+8 vs 64+9, PA 122 vs 125, MI 99 vs 103, TX 84 vs 89. Acres within ~1-5% of official figures (Custer, Baxter, Anza-Borrego, Big Basin).

City parks are not included. Rhode Island and Vermont have no county governments. Hours and fees change; check with the county before you go.
Source: USGS Protected Areas Database of the U.S. (PAD-US 4.1); OpenStreetMap contributors (non-official) for some names, hours, phones, fees and camping
Why we trust it: Compared with counties' own totals: Fairfax 25,619 vs 23,000 acres, Miami-Dade 10,625 vs 13,454, Maricopa 92,057 vs 120,000. Some big systems are only partly mapped in PAD-US (Cook ~51% of acres, King ~53%, Los Angeles ~27%, since many of LA's natural areas sit on state or federal land).
What crime by race data is on the map?
6 layers: White, Black, American Indian, Native Hawaiian, Asian, Hispanic or Latino.
White
Statewide counts and rates of people recorded at each stage of the justice system, by the race recorded on the report. Offenders and victims come from police incident reports sent to the FBI; arrests come from each state's own crime-reporting program; prison counts come from state prison records via BJS. Rates are per 10,000 residents of the same group. No rate is shown when fewer than 60% of a state's residents are covered, when fewer than 20 people are counted, or when a state does not publish usable data; counts of 1-2 show as 'fewer than 3'.
Source: FBI NIBRS 2025 (offenders, victims; tabulated by Map the Block); state crime-reporting programs 2020-2025 (arrests); BJS National Prisoner Statistics 2023 (prison); Census Bureau Vintage 2025 population estimates
Why we trust it: Sum of the 51 state NIBRS tabulations is within 0.08% of the FBI's national Tables 7 and 11 (every race cell within 0.14%). Census county totals match the state file exactly. Washington's own 2025 report matches our counts within 0.1-3.5% for robbery, burglary, larceny and car theft, with the same race shares; Arizona, Nevada, Texas, Virginia and South Carolina reports agree within the differences in offense definitions and year. State arrest totals were compared with FBI Table 69 (details in research/77).
Black

What history data is on the map?
1 layer: Historical markers.
Historical markers
States without open official marker data are filled from OpenStreetMap, which is thin in places (ND, SD, AK). Wisconsin and Alabama official lists are not shown yet.
Source: Texas Historical Commission; Pennsylvania Historical & Museum Commission; Virginia Dept. of Historic Resources; Georgia, Michigan, Maryland, Delaware, Indiana, Vermont and Montana marker programs; OpenStreetMap contributors (ODbL, non-official)
Why we trust it: Totals vs the programs' own counts: TX 1.00, PA 0.98, VA 0.97, DE 0.99, MD 0.96, MI 1.01, GA 1.11. Spot-checked locations within ~200 m of official pages.
What sacred sites data is on the map?
2 layers: Sacred Sites, Tribal lands.
Sacred Sites
Ancient and historic sites only; active churches, mosques, synagogues and modern temples are not included. Indigenous sites are shown only where there is evidence they are open to the public. Many places are sacred to living communities: visit respectfully, stay on paths and follow posted rules.
Source: Wikidata (CC0, non-official); OpenStreetMap contributors (ODbL, non-official); Wikipedia (non-official); National Park Service and National Register of Historic Places (official)
Why we trust it: 38 of 39 sites on six continents within ~100 m of their Wikipedia or nps.gov location. France: 96% of the Ministry of Culture's protected dolmens and menhirs have a site here within 500 m. All 13 U.S. sites with an NRHP number sit within 500 m of the official point.
Tribal lands
Census statistical boundaries of American Indian reservations and off-reservation trust land, state reservations, Oklahoma tribal areas, Alaska Native village areas, tribal statistical areas and Hawaiian home lands, shown for reference. These are not legal or survey boundaries and do not define jurisdiction or ownership. A reservation and its off-reservation trust land are shown as one area, as the Census publishes them. Figures are American Community Survey 5-year estimates (2020-2024); small areas have wide margins of error, and blank rows mean the Census published no estimate.
Source: U.S. Census Bureau: TIGER/Line 2025 American Indian/Alaska Native/Native Hawaiian Areas, 2025 Gazetteer, American Community Survey 2020-2024 5-year estimates (Summary File), 2020 Census
Why we trust it: All 704 Census 2025 AIANNH areas present (matches the 2025 Gazetteer); land area within 0.005 sq mi of the Gazetteer for every area; population, income, poverty, housing units and home value match data.census.gov for 12 sample areas (Navajo Nation, Pine Ridge, Osage, Cherokee OTSA, Nanakuli and Waimanalo Hawaiian home lands, Bethel and Barrow villages, Hopi, Shinnecock, Lumbee, Qualla Boundary).
Can I reuse this data?
Yes, with credit. Map the Block uses every source under its published terms, open licence or public-records status, and only where the source allows automated collection. Most layers are built from U.S. federal, state and local government records, which are generally public domain or published as open data; each layer above names its source, and that source’s own terms apply. Layers that use OpenStreetMap are © OpenStreetMap contributors under the Open Database License (ODbL 1.0). Layers that use Overture Maps are under the CDLA-Permissive-2.0 or ODbL licence of that release. Non-government sources named on a layer (for example the Guttmacher Institute) keep their own terms.
The way Map the Block combines, checks and describes these sources, and the text of this site, are © Phulax LLC. You may quote figures and link to any page with credit to “Map the Block (maptheblock.com)”. For bulk or commercial use, see the Data API.
How is the data checked?
Before any layer goes live it passes automatic checks: record counts, value ranges and a comparison with a second, independent source (for example FBI totals for city crime feeds, Census totals for population counts, EPA and FEMA lists for hazards). If a check fails, the old version stays live. Layers marked “single source” have no second source yet.
