"People are spending more time in prison, and the longest prison terms are getting longer.

To better understand long prison terms, we took a new approach to measuring how much time people spend in US prisons. We looked at annual snapshots of prison populations to see how long people had been in prison so far and compared those snapshots over time. This allowed us to include time served by people who are usually overlooked by more traditional methods."

"At year end 2015, the United States had an estimated 1,526,800 prisoners under the jurisdiction of state and federal correctional authorities. This was the smallest U.S. prison population since 2005 (1,525,900 prisoners). The prison population decreased by more than 2% from the number of prisoners held in December 2014. This was the largest decline in the number of persons under the jurisdiction of state or federal correctional authorities since 1978."

This is a list of ALL the Data Analysis Tools that the BJS has to offer.

"Correctional Officers and Jailers - Guard inmates in penal or rehabilitative institutions in accordance with established regulations and procedures. May guard prisoners in transit between jail, courtroom, prison, or other point. Includes deputy sheriffs and police who spend the majority of their time guarding prisoners in correctional institutions."

This is a listing of the Data on Common Health Problems offered by the Center for Disease Control (CDC).

"Key Statistics provides easy access to trend data from BJS's [Bureau of Justice Statistic's] data collections. Each Key Statistic includes a description, table, and graph, along with links to related information, including publications that include the statistics, data collections, and any available data analysis tools." Key Statistics are provided for the total U.S. correctional population, prisoners, jail inmates, probationers, parolees, rate of correctional supervision, incarceration rate, community supervision rate, and executions. More topics will be added in the future.

Corrections Key Statistics

In September, the Brennan Center analyzed available crime data from the nation's 30 largest cities, estimating that these cities would see a decline in crime and murder in 2018. Our report, Crime and Murder in 2018: A Preliminary Analysis, concluded that crime and murder in 2018 are again declining nationwide, continuing the historic downward trend.

This analysis updates the September report and finds that, where data were available, rates of crime, violent crime, and murder in major American cities are estimated to decline through the end of 2018. However, murder rates in some cities remain above 2015 levels, demonstrating a continued need for evidence-based solutions to violent crime.


“This report addresses (1) the number and nationalities of incarcerated criminal aliens; (2) the types of offenses for which criminal aliens were arrested and convicted; and (3) the costs associated with incarcerating criminal aliens and the extent to which DOJ's methodology for reimbursing states and localities for incarcerating criminal aliens is current and relevant.” Statistics are provided for criminal alien incarcerations and nationalities, criminal alien arrests and convictions, estimated costs of criminal alien incarcerations; and agency and third-party comments. “Based on our random sample, GAO estimates that the criminal aliens had an average of 7 arrests, 65 percent were arrested at least once for an immigration offense, and about 50 percent were arrested at least once for a drug offense. Immigration, drugs, and traffic violations accounted for about 50 percent of arrest offenses. About 90 percent of the criminal aliens sentenced in federal court in fiscal year 2009 (the most recently available data) were convicted of immigration and drug-related offenses. About 40 percent of individuals convicted as a result of DOJ terrorism-related investigations were aliens.” The average cost to incarcerate criminal aliens is $1.5 billion per year.

Recent data analyses on jail incarceration—taken from Vera’s Incarceration Trends tool—reveal that although significant racial disparities still exist between black and white jail incarceration rates, incarceration rates for black people are declining, while rates for white people are rising. This report dives into the data on black and white incarceration trends from 1990 to 2013, and poses several questions for further exploration that might explain why these rates are shifting. However, the report also argues that we need more data to fully understand the causes and consequences of racial disparities in incarceration—and to begin enacting more race-conscious jail reduction efforts. 

"Story Highlights: Perceptions of nationwide crime unchanged from 2015, Perceptions of local crime also steady, 60% of Americans believe crime problem in U.S. extremely or very serious"
