Yesterday, the Sunlight Foundation announced the launch of the Hall of Justice, a new inventory of publicly available criminal justice datasets. Currently, it contains information about and links to almost 10,000 datasets and research documents about every state and the federal government. The inventory includes information from both government and academic sources. It covers a number of categories including Corrections, Courts, Crime, Financial, Juvenile Justice, Law Enforcement, Victims, and Miscellaneous (covering Data Accessibility, Guns, Indian Country Justice System, Military Justice System, and State-Specific Topics).
You can search for data in a few different ways. You can browse by jurisdiction or by category and subcategory. You can also do a keyword search for relevant datasets. Once you have your results, the list can be filtered in other ways including by author group, by sector (such as government, nonprofit, or private), and by how the information can be accessed. The information in the inventory was collected between September 2014 and October 2015.
