Prison Policy Initiative releases tenth edition of its flagship report, now "Mass Incarceration: The Whole Pie 2024"

It is pi day, which for the last decade has meant a special treat for sentencing fans and criminal justice data fans: the Prison Policy Initiative's latest, greatest version of its amazing incarceration "pie" graphic and associated report. The latest report "Mass Incarceration: The Whole Pie 2024" provides a spectacular accounting of the particulars of who and how of incarceration in the United States. As I have said in the past, the extraordinary "pies" produced by PPI impart more information in a few images than just about any other single resource I know about (and this PPI press release has the main visual and other highlights). Here is part of this latest pie report's introductory text and  overview (links and format from the original):

The various government agencies involved in the criminal legal system collect a lot of data, but very little is designed to help policymakers or the public understand what’s going on. The uncertainty that results muddies the waters around our society’s use of incarceration, giving lawmakers and lobbyists the opportunity to advance harmful policies that do not make us safe. As criminal legal system reforms become increasingly central to political debate — and are even scapegoated to resurrect old, ineffective “tough on crime” policies — it’s more important than ever that we get the facts straight and understand the big picture.

Further complicating matters is the fact that the U.S. doesn’t have one criminal legal system; instead, we have thousands of federal, state, local, and tribal systems. Together, these systems hold over 1.9 million people in 1,566 state prisons, 98 federal prisons, 3,116 local jails, 1,323 juvenile correctional facilities, 142 immigration detention facilities, and 80 Indian country jails, as well as in military prisons, civil commitment centers, state psychiatric hospitals, and prisons in the U.S. territories — at a system-wide cost of at least $182 billion each year.

This report offers some much-needed clarity by piecing together the data about this country’s disparate systems of confinement. It provides a detailed look at where and why people are locked up in the U.S., and dispels some common myths about mass incarceration to focus attention on overlooked issues that urgently require reform....

While this pie chart provides a comprehensive snapshot of our correctional system, the graphic does not capture the enormous churn in and out of our correctional facilities, nor the far larger universe of people whose lives are affected by the criminal legal system. In 2022, about 469,000 people entered prison gates, but people went to jail more than 7 million times. Some have just been arrested and will make bail within hours or days, while many others are too poor to make bail and remain in jail until their trial. Only a small number (about 102,700 on any given day) have been convicted, and are generally serving misdemeanors sentences of under a year. At least 1 in 4 people who go to jail will be arrested again within the same year — often those dealing with poverty, mental illness, and substance use disorders, whose problems only worsen with incarceration.
