Mapping the neighborhoods, cities, and counties that people in state prisons come from

How does a community’s incarceration rate correlate with other aspects of its welfare, such as its rates of poverty and illness? To find out, we need to know precisely which communities people in prison come from. But this data is surprisingly difficult to obtain and turn into geographic tables.

We published this data for two states — New York and Maryland — in the reports below for other researchers to download and use. These reports provide a powerful new tool for studying how mass incarceration has impacted specific neighborhoods, and how incarceration tracks with other measures of community health.

The geography of incarceration in New York

Our report maps where people in New York state prisons come from, down to the neighborhood level. In the appendices of the report, readers can download the geographic data at several levels, including counties, cities, and state legislative districts. We also explain how readers can use this data to study how incarceration relates to community well-being.

Corrections spending in Baltimore city

This 2015 report maps where people in Maryland prisons are from, and shows that Maryland is spending $288 million every year to incarcerate people from disadvantaged communities in Baltimore. In the appendices of the report, readers can download the geographic data at several levels to use for their own research.
