From the abstract:
Presents advance counts of prisoners under the jurisdiction of state and federal correctional authorities on December 31, 2012, collected in the National Prisoner Statistics Program. This advance report provides a timely estimate of the 2012 yearend prison populations and compares changes in the prison population during 2012 to changes from yearend 2002 through yearend 2011. The report describes the third consecutive year of decline in the state prison population and growth in the federal prison population. It includes estimates of imprisonment rates by jurisdiction for prisoners sentenced to more than one year and estimates of the distribution of state prisoners by sex, race or Hispanic origin, and offense. The report examines the continued impact of California’s Public Safety Realignment on California’s prison population and on national totals and trends.
