Women's Mass Incarceration: The Whole Pie 2019

women's pie 2019 report thumbnail Women in the U.S. experience a starkly different criminal justice system than men do, but data on their experiences is difficult to find and put into context. We fill this gap in the data with a rich visual snapshot of how many women are locked up in the U.S., where, and why. Alongside our "big picture" chart, this 2019 update to our 2017 and 2018 reports on women's incarceration features a close-up view of women in local jails.
