Understanding the Data
Violent crime includes murder, rape, robbery, and aggravated assault as defined by the FBI's Uniform Crime Reporting (UCR) program. Rates are per 100,000 residents and based on the latest 2024 data.
Why population matters: Cities under 10,000 are excluded from this ranking because a single incident can produce an extremely high per-capita rate. A city of 500 with one murder has a "murder rate" of 200/100K — statistically meaningless.
Not all crime is reported. FBI data only captures crimes reported to police. The Bureau of Justice Statistics estimates only ~40% of violent crimes are reported. See our hidden crime estimates →
