Crime in cities. The Marshall Project has collected and analyzed four decades of FBI data “on the most serious violent crimes in 68 police jurisdictions.” The FBI data covers 1975 through 2014; the reporters “also obtained data directly from 61 local agencies for 2015 — a period for which the FBI has not yet released its numbers.” Between 2010 and 2015, violent crime increased most in Milwaukee (+11%) and declined most in Prince George’s County, Md. (-22%).
