March 19, 2025:
Join Prison Policy Initiative’s Advocacy Department at 1 PM EST on Wednesday, March 19, 2025, for a webinar about understanding recidivism. We will cover strategies from our recidivism toolkit, including an overview of recidivism statistics and what they really mean, how to combat the “Willie Horton” effect, and ways that advocates can transform the narrative around reentry to make it less focused on negative outcomes and more focused on the ways that returning citizens contribute to their communities.

Public Use Microdata Area (PUMA). 2019: Public Use Microdata Areas (PUMAs) are statistical georaphic areas defined for the dissemination of Public Use Microdata Sample (PUMS) data and the American Community Survey (ACS) estimates. PUMAs have a minimum population of 100,000, and are aggregated from Census tracts and Community Districts. For information on PUMAs from the Census Bureau, see: https://www.census.gov/programs-surveys/geography/guidance/geo-areas/pumas.html.
Number of people in state prison from NYC PUMA, 2010: This is the number of people from each NYC PUMA in state prison as of 2010. See the methodology section of the report.
Census population, 2010: This is the population of the NYC PUMA as reported in the 2010 Census.
Total population, 2010: This is the total population of the NYC PUMAas reflected in the 2010 Census plus the imprisoned population.
Imprisonment rate per 100,000: This is the number of imprisoned people divided by the total population and then multiplied by 100,000. It allows ready comparison of the frequency of imprisonment between PUMAs of different population sizes.
