🔎About this data
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.
