Which U.S. cities of 100,000 or more 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 313 U.S. cities of 100,000 people or more whose police reported a full year to the FBI, about 51.3 per 100,000 people, followed by Birmingham, AL (43.0) and Memphis, TN (31.0); the U.S. rate was about 4.4. Search for any city to see its rate and rank. In a city of 100,000, one more or one fewer murder moves the rate by 1, so a smaller city's rate can jump from year to year. Departments that didn't report a full year are left out, and each rate is per person the department serves; a few serve their whole county. A city's rate also depends on where its borders fall, so compare cities with care.

The interactive chart needs JavaScript. The numbers are on the chart's page.
In the Census Bureau's 5-year survey ending in 2024, the typical household in District of Columbia earned $109,870 a year, the most, followed by Massachusetts ($103,960) and Maryland ($103,678). Mississippi was lowest at $56,447, and the U.S. median was $80,734. These are 5-year estimates in 2024 dollars, each with a margin of error.
How to read this chart
Each bar is the median household income in a state: half of households earn more and half earn less. The dashed line is the whole U.S., for comparison. These are survey estimates, and each has a margin of error: the true value is likely within that range, so states with overlapping ranges may not really differ.
Questions to discuss
- Find your state. Is it above or below the U.S. median, and by about how much?
- Why do statisticians often use the median instead of the average (mean) for income?
- Housing and groceries cost more in some states. What would you need to know to compare what these incomes can buy?
