No area has zero risk

A high Crime Index score means lower reported crime relative to other US cities — it is not a guarantee of safety. Reported crime is not the same as actual crime. Research on the gap between crime that occurs and crime that gets reported to police — often called the "dark figure" of crime — estimates that roughly 40% of violent crime and about a third of property crime go unreported each year. Every index built on official statistics, including this one, necessarily undercounts real crime. That gap is exactly why homicide — the offense with the smallest dark figure — anchors the calculation instead of a more commonly reported but less reliable category like theft.

Frequently asked questions

Is Nampa safe?
Nampa has a Crime Index of 79 out of 100 (grade B — safe) for 2025, based on FBI-reported violent and property crime rates relative to other US cities. That ranks it #4 of 8 cities in Idaho by reported crime. Reported crime is not the same as actual crime. Research on the gap between crime that occurs and crime that gets reported to police — often called the "dark figure" of crime — estimates that roughly 40% of violent crime and about a third of property crime go unreported each year. Every index built on official statistics, including this one, necessarily undercounts real crime. That gap is exactly why homicide — the offense with the smallest dark figure — anchors the calculation instead of a more commonly reported but less reliable category like theft.
What does a "B" grade mean?
A "Safe" grade means Nampa's severity-weighted crime rate falls in the 75–87 range on the Crime Index, out of a national distribution of every city we track for 2025. Grades are calibrated against the national distribution of every area we track for the same data year — they describe an area's relative standing, not an absolute promise. A "Very safe" grade means an area sits among the lowest-crime places in the country with usable data, not that nothing ever happens there.
What is the most common crime in Nampa?
The most frequently reported offense in Nampa for 2025 was larceny-theft, with 637 reported incidents. See the full breakdown by offense above for how violent and property crime compare to the US average.
Is crime in Nampa getting better or worse?
Reported crime in Nampa is down 46% since 2021, so the trend is improving. Year-to-year figures can shift with FBI reporting changes, not just real crime.
What are the odds of being a victim of crime in Nampa?
Based on 2025 reported rates, Nampa residents face roughly a 1 in 323 annual chance of a violent crime and about 1 in 148 for a property crime, calculated city-wide. Your individual risk varies widely by neighborhood, time of day, and circumstances.
How does Nampa compare to other US cities?
Nampa is safer than 66% of the 759 US cities we track for 2025, ranked by Crime Index. Its violent-crime rate is +43% vs the Idaho average and its property-crime rate is +10% vs the Idaho average.
Does reported crime equal real crime?
No. National research on the dark figure of crime estimates that roughly 40% of violent crime and about a third of property crime are never reported to police, so any index built on official statistics — including this one — measures a floor on real crime, not a ceiling. That's part of why the index leans most heavily on homicide, the category with the smallest reporting gap.
