In the 12 months through June 2025, the leading cause of death for Americans aged 15 to 24 was unintentional injuries, at 24.0 deaths per 100,000 people that age. Suicide (13.4) and homicide (10.0) came next. Unintentional injuries include accidental overdoses and traffic crashes. Deaths from disease are rare at this age. The numbers are provisional.

Which big U.S. cities have the highest murder rates?
The interactive chart needs JavaScript. The numbers are on the chart's page.
In 2025 St. Louis, MO had the highest murder rate of the 89 biggest U.S. cities whose police reported a full year to the FBI, about 51.3 per 100,000 people, followed by Memphis, TN (31.0) and Cleveland, OH (28.0). Irvine, CA (0.0) and Plano, TX (0.7) had the lowest; the U.S. rate was about 4.4. Departments that didn't report a full year are left out (for 2025, New Orleans, Orlando and St. Petersburg, Florida). Each rate is per person the department serves, and a few, such as Las Vegas, Honolulu, Jacksonville and Louisville, serve their whole county. A city's rate also depends on where its borders fall, so compare cities with care.
How to read this chart
Each bar is the number of murders in a city in one year for every 100,000 people its police department serves. The dashed line is the U.S. rate. Murders are rare, so in a smaller city a handful more or fewer in one year can move its rate and its rank a lot.
Questions to discuss
- How many cities on the chart have a murder rate above the U.S. rate, and how many are below it?
- Why does a chart like this use murders per 100,000 people instead of the total number of murders in each city?
- A city's rank can jump from one year to the next. Why might small numbers make rates bounce around?
