Crime trends since 2023
How to read this chart
A declining line can mean several things: fewer crimes occurred (effective policing, courts, or deterrence at work), fewer crimes were reported (agencies dropped out of NIBRS), or crimes were reclassified into different categories. A rising line carries the same ambiguity in reverse. FBI data captures only what agencies submit — see The Gap to verify which agencies in Iowa are still reporting.
What this data says

Iowa's rate sits below the national median. It ranks #42 of 51 states by homicides per capita (1 = highest). The national median across all states is 3.2 per 100,000.
