Data resources

National Archive of Criminal Justice Data

The National Archive of Criminal Justice Data (NACJD), at ICPSR, is the central clearinghouse for criminology and criminal justice research data. All data developed through course of a NIJ-funded grant projects are archived with ICPSR, much of it in NACJD. As well, data is provided to NACJD by the Bureau of Justice Statistics (BJS), Office of Juvenile Justice and Delinquency Prevention (OJJDP), U.S. Sentencing Commission, and the Federal Judicial Center.

Most data sets are provided as statistical files, with choice of SAS or SPSS formats, along with a Codebook in PDF format. Oftentimes, the data files will include a FIPS code, census tract code, or other code that allows you to join these data files to GIS data.

Data available in NACJD are available to the public, free of charge. Other ICPSR data are available freely to members - over 500 universities and government organizations. However, non-members may access data on a fee-basis. Some ICPSR data sets are restricted, to ensure confidentiality and privacy of the research subjects and respondents, and require additional procedures to obtain that data.

Other Data Sources

Dr. Andrew Reamer gave an overview of data sources available for crime analysis and research at the Ninth Crime Mapping Research Conference in Pittsburgh. The United States Census Bureau is a source for not only data collected through the decennial census, but they produce other data products including the American Community Survey. The HUD Office of Policy Development and Research provides data about mortgages, low-income housing projects, and other such information. The U.S. Department of Transportation makes data available that comes from its National Household Transportation Survey (NHTS). There are a number of data portals that provide access to this data, as well as geospatial data.
