What is the crime rate in Clark County?
Over 2021-2025, the county's police agencies sent the FBI reports of about 3 violent and 3 property crimes per year. That is 2.6 violent crimes per 1,000 residents, 27% lower than the South Dakota rate (3.5), and 30% lower than the U.S. rate (3.7). Property crime ran at 2.6 per 1,000, against 15.8 statewide.

Most crime never reaches the police, so these are reported crimes, a floor rather than the full count. In 2024 about half of violent crimes (48%) and about 3 in 10 property crimes (31%) were reported to police (U.S. Justice Department, National Crime Victimization Survey). Rates also depend on how completely each agency reports to the FBI. County figures add up the city police and sheriff reports in the county (1 agencies; 30% of residents covered).
