About these categories

The FBI publishes city totals by family, not a full breakdown by offence, so homicide is the only type Ada County Sheriff's Office reports separately here. Red means more than before, green means fewer. “Not yet” means the site does not have that month from a year earlier.

Safety varies a lot by neighborhood, so the figure for the whole area is only a starting point.

Is there a crime map for Ada County?

This site does not have one for Ada County. The figures on this page come from the FBI, which receives city totals rather than locations, so CurrentCrimeMap shows how Ada County (Sheriff) compares with nearby places such as Boise, ID instead of a street-level map.

What is the crime rate in Ada County (Sheriff)?

Where does the data come from?

From Ada County Sheriff's Office, via FBI Crime Data Explorer (dataset ID0010000). We count reported incidents by month and offense type and divide by the population the agency serves, as the FBI reports it. Reported crime undercounts actual crime; see the methodology page for what the numbers leave out.

Moving to or visiting Ada County (Sheriff)

12 months to September 2026

What these numbers leave out: most crime never reaches the police. In the federal victim survey (BJS, 2024), about half of violent crimes and less than a third of property crimes were reported, and only a quarter of everyday thefts. Rates are per resident, so busy downtowns and tourist areas look worse than they are for the people who visit them.

The official source is FBI Crime Data Explorer. For what to look for, and what not to read into a rate, see how to read US crime numbers.
