The phenomenal growth of penal confinement in the United States in the last quarter of the twentieth century is still a public policy mystery. Why did it happen when it happened? What explains the unprecedented magnitude of prison and jail expansion? Why are the current levels of penal confinement so very close to the all-time peak rate reached in 2007? What is the likely course of levels of penal confinement in the next generation of American life? Are there changes in government or policy that can avoid the prospect of mass incarceration as a chronic element of governance in the United States? This study is organized around four major concerns: What happened in the 33 years after 1973? Why did these extraordinary changes happen in that single generation? What is likely to happen to levels of penal confinement in the next three decades? What changes in law or practice might reduce this likely penal future?
