This is the home of the U.S. Government’s open data. Here you will find data, tools, and resources to conduct research, develop web and mobile applications, design data visualizations, and more.

These fact sheets provide at-a-glance information about how many people are locked up in both state prisons and county jails and shows where the state stands on a variety of metrics, so that policymakers and the public can better determine where to target reforms.

In addition to calculating jail and prison incarceration trends, Vera researchers combined information about prisons and jails to produce a total incarceration ranking.

"The Justice Atlas of Sentencing and Corrections is an online tool for mapping the residential distribution of people involved in the criminal justice system. It uses aggregated address data to map the flow of people being removed to prison, reentering communities from prison, and the standing population concentrations of people under parole or probation supervision."

"Welcome to the Justice Mapping Center (JMC) website. We specialize in using computer mapping—otherwise known as Geographic Information Systems or GIS—to help our partners better understand, evaluate, and communicate criminal justice and other social policy information. Our mapping studies are used by legislators, government agencies, research institutes, technical assistance providers, and the media. Explore our site to find out more about us and visit our Project Gallery to view some of our recent studies."

On this Portal, you will find comparative performance measures for counties nationwide. The measures get at how cases are being handled from arrest to post-conviction. Wherever possible, the data can be filtered by race/ethnicity; indigency; sex; age; offense type and severity.

Hundreds of data indicators can be mapped. These are organized according the topical areas of county administration, county employment, county finance, country structure, demographics, economy, education, energy and environment, federal funding, geography, health and hospitals, housing and community development, justice and public safety, public amenities, public lands, social services, transportation, utility, and water, sewerage, and solid waste management. You can search by city-zip code, county, or state.

"Understanding criminal justice-involved populations and their reentry is critical to understanding urban poverty. Nationwide, roughly 650,000 individuals return from state and federal prisons to their communities each year. This amounts to about 10,000 individuals returning a week or 75 individuals returning an hour. While these numbers may be hard to digest in the abstract, they have a profound impact on the communities to which individuals return—often low-income communities of color that are ill-equipped to confront the systemic barriers that impede successful reentry."

The Sentencing Project compiles state-level criminal justice data from a variety of sources. Using the three tabs below, you can navigate between interactive features that allow you to access and use these data. In the State Data Map, you can roll over states for a quick snapshot of key figures from each state and click on any state to see more data. You can also use the dropdown menu to display different datasets on the map. Under Detailed State Data, you can access full datasets for each state and compare states. In State Rankings, you can see how states stack up against each other in different areas.
