Frequently asked questions
Where can I find unsolved murder statistics by state?
The Crime Solvers Central statistics dashboard breaks down individual unsolved homicide cases by state, decade, age and sex, and the FBI Crime Data Explorer and the Murder Accountability Project publish homicide and clearance data by state.
What is a homicide clearance rate?
The share of homicides police clear in a year, usually by arrest. It is reported to the FBI by police agencies. A lower clearance rate means more cases go unsolved.
Why are unsolved murder numbers different between sources?
Sources count different things: clearance rates from police reports to the FBI, or lists of individual cases. Not every agency reports every year, and no case list is complete.
Can journalists cite the Crime Solvers Central statistics?
Yes. Each database page has a suggested citation, and the numbers are updated nightly.
