The Deadliest County in Each U.S. State

Since the start of the COVID-19 pandemic, homicide rates have risen significantly in the United States. From 2014 to 2019, annual homicides ranged from 15,775 to 19,393, with an average rate of 5.6 per 100,000 people, according to the National Center for Health Statistics. Between 2020 and 2023, the rate climbed to 7.3 per 100,000, with at least 22,800 reported homicides each year.

There is no single explanation for the increase. Early in the pandemic, school closures and mass layoffs left more adults and teens at home as unemployment surged, contributing to a spike in violence. The rise was particularly pronounced in high-poverty neighborhoods, where economic opportunity and social engagement were already limited.

The growing prevalence of firearms has also played a role. The U.S. Department of Justice reports that 80% of homicides in 2023 involved a firearm, up from 68% in 2014. Gun sales surged during the pandemic, with FBI background checks indicating nearly 22.7 million firearms purchased in 2020 alone. Although sales have declined since then, they remain historically high.

While national trends provide context, violent crime is often driven by local conditions such as poverty, income inequality, housing instability, population density, strained police-community relations, and gang activity. As a result, homicide rates vary widely across the country.

Using data from County Health Rankings and Roadmaps, a program of the University of Wisconsin Population Health Institute, Tempo identified the county with the highest homicide rate in each state. Counties were ranked by average homicide rate using data from 2016 through 2022. The analysis includes 1,425 counties and county equivalents with available data. Supplemental poverty data comes from the U.S. Census Bureau's 2023 American Community Survey. Homicides are defined as deaths resulting from assault.

Among the counties on this list, homicide rates range from 2.4 to 57.4 incidents per 100,000 residents and exceed their respective state averages by as much as 47.5 points.

Many of the counties with the highest homicide rates also have above-average poverty levels, often by more than 5 percentage points compared with the state overall. Still, some counties on the list remain relatively safe by national standards. In states such as New Hampshire and Vermont, even the highest-ranking counties report fewer than three homicides per 100,000 residents annually. Because homicide rates are calculated relative to population, even a single incident in a small community can significantly affect the local rate.

These are the murder capitals of every state.
