ANNUAL CRIME AND SAFETY RANKING
Safest Cities in America
As a prospective homeowner, nothing could be more important than the safety of you and your family when choosing a home. Our data science team carefully curates data from several official sources to provide an accurate representation of a city’s crime and safety. We create a ranking of cities at both the national level, and the state level, in order to help you choose your new home.
Data is gathered from several official sources, including the FBI National Incident-Based Reporting System (NIBRS). The crime and safety score for each city below incorporates a weighted list of offenses, based on the severity of the crime. For example, a crime like rape or manslaughter would be rated heavier (more severe) than petty theft or fraud. The numbers are also normalized by the city’s population, so the dynamic of crime in a larger city vs. a smaller city is also taken into account. These raw safety scores are then ranked both nationally and by state to arrive at a ranking for all the cities in the United States.
