Current project - Crimes in the US

The project harmonizes incident data from police departments in any US cities with more than 100,000 population. 77974249 rows of incidents from 68 city-level police departments are mapped to 16224 Census tracts and 29 FBI NIBRS offense categories.

An overview of the data can be found in Data. The data processing procedures can be found in Documentation. The offense categories can be found in NIBRS Offenses. If you are looking to
