After decades of stability from the 1920s to the early 1970s, the rate of imprisonment in the United States has increased fivefold during the last four decades. The U.S. penal population of 2.2 million adults is by far the largest in the world. Just under one-quarter of the world's prisoners are held in American prisons. The U.S. rate of incarceration, with nearly 1 out of every 100 adults in prison or jail, is 5 to 10 times higher than the rates in Western Europe and other democracies. The U.S. prison population is largely drawn from the most disadvantaged part of the nation's population: mostly men under age 40, disproportionately minority, and poorly educated. Prisoners often carry additional deficits of drug and alcohol addictions, mental and physical illnesses, and lack of work preparation or experience. The growth of incarceration in the United States during four decades has prompted numerous critiques and a growing body of scientific knowledge about what prompted the rise and what its consequences have been for the people imprisoned, their families and communities, and for U.S. society. The Growth of Incarceration in the United States examines research and analysis of the dramatic rise of incarceration rates and its affects. This study makes the case that the United States has gone far past the point where the numbers of people in prison can be justified by social benefits and has reached a level where these high rates of incarceration themselves constitute a source of injustice and social harm. The Growth of Incarceration in the United States examines policy changes that created an increasingly punitive political climate and offers specific policy advice in sentencing policy, prison policy, and social policy. The report also identifies important research questions that must be answered to provide a firmer basis for policy. This report is a call for change in the way society views criminals, punishment, and prison. This landmark study assesses the evidence and its implications for public policy to inform an extensive and thoughtful public debate about and reconsideration of policies.

After conducting a comprehensive literature search, the authors undertook a meta-analysis to examine the association between correctional education and reductions in recidivism, improvements in employment after release from prison, and other outcomes. The study finds that receiving correctional education while incarcerated reduces inmates' risk of recidivating and may improve their odds of obtaining employment after release from prison.

Assesses the effectiveness of correctional education for both incarcerated adults and juveniles, presents the results of a survey of U.S. state correctional education directors, and offers recommendations for improving correctional education.

A Discussion paper from the BJS-Princeton Project.

"[The report] finds that supervision -– probation and parole -– drives high numbers of people, disproportionately those who are Black and brown, right back to jail or prison, while in large part failing to help them get needed services and resources. In states examined in the report, people are often incarcerated for violating the rules of their supervision or for low-level crimes, and receive disproportionate punishment following proceedings that fail to adequately protect their fair trial rights."--Publisher website.
