UCR — Uniform Crime Reporting
Published by Federal Bureau of Investigation (FBI)· annual
The FBI's annual crime statistics program, with data on violent crime, property crime, and police staffing voluntarily reported by 18,000+ U.S. law enforcement agencies.
In Detail
The Uniform Crime Reporting Program (UCR) is the FBI's decades-old data collection program that aggregates crime statistics from law enforcement agencies nationwide. Data includes violent crimes (homicide, rape, robbery, aggravated assault), property crimes (burglary, larceny, motor vehicle theft, arson), and law enforcement staffing levels (officers per 1,000 residents). ValiFit uses UCR data to compute the Safety ROI composite — police officers per 1,000 residents divided by violent crimes per 1,000 residents — which measures how much enforcement capacity exists relative to actual crime levels. Higher Safety ROI = more enforcement per crime, federally defensible methodology that does not penalize neighborhoods based on demographic composition.
