The Survey of Prison Inmates Data Analysis Tool (SPI DAT) is a new dynamic analysis tool that modernizes public access to the most recent SPI data (2016) with interactive visualizations. The SPI DAT allows users of all technical skill levels to readily analyze data, view selected charts, and create custom charts for a range of characteristics of the U.S. prison population. Filters can be selected to provide detailed results by specific characteristics. Users can choose to create data visualizations for persons in federal prisons, persons in state prisons, or all persons in U.S. prisons in 2016. Other modern features enable users to view additional statistics through the chart tooltip, to display or hide chart footnotes, and to download results.
The SPI is a national, cross-sectional survey of the state and sentenced federal prison populations that is conducted periodically by the Bureau of Justice Statistics. The SPI?s primary objective is to produce national statistics of the state and sentenced federal prison populations across a variety of topics.
The Bureau of Justice Statistics of the U.S. Department of Justice is the principal federal agency responsible for collecting, analyzing, and disseminating reliable statistics on crime and criminal justice in the United States. Alexis R. Piquero, PhD, is the director.
