Criminal justice statistics
The prevalence of drug use in the male arrestee population is determined by the Arrestee Drug Abuse Monitoring Program II (ADAM II). The major drugs monitored are marijuana, crack and powder cocaine, heroin and other opiates, and methamphetamine. Four sections follow an executive summary: ADAM II overview; the ADAM II sample; drug use and drug market activity among arrestees; and summary and conclusions. The most commonly detected drug was marijuana followed by cocaine metabolites.

"Social science research has time and again come to the robust conclusion that exposure to the criminal justice system has profound and intergenerational negative effects on communities that experience disproportionate incarceration rates. It is imperative that we are able to measure the extent to which the criminal justice system disparately impacts our communities." You can find this information easily by referring to this briefing. It does an excellent job in synthesizing the information that is known about the disproportion of incarcerated minorities in the United States at the state level. In addition to incarceration rates by race/ethnicity, the following statistics (if available) are provided for each state and the U.S. federal prison system for the period 1978-2012: the degree to which Whites are underrepresented in the particular state's prisons and jails; Hispanics are overrepresented; Blacks are overrepresented; American Indians are overrepresented; Native Hawaiians are overrepresented.
"Parole decision-making functions as a crucial mechanism channeling people in and out of prison. This report combines multiple data sources and, for the first time, provides an overview of the movements between prison and parole for each state, focusing on the decision points of parole release and parole revocation. This information allows for a comprehensive picture of each state, both as a snapshot and longitudinally. For each state, information is presented on prison and parole rates over time, the percentage of prison admissions that are due to people on conditional release, the percentage of hearings by the parole board that result in parole being granted, the rate of re-incarceration for parolees, and the percentage of parolees who exit parole due to an incarceration versus a successful completion of supervision" (website).
This report presents "state-level estimates of the number of inmates confined in local jails at year end 2013, by sex, race, and Hispanic origin. This report provides information on changes in the incarceration rate, average daily population, admissions, expected length of stay, rated capacity, percent of capacity occupied, and inmate-to-correctional officer ratios. It also includes statistics, by jurisdiction size, on the number of inmates confined to jail and persons admitted to jail during 2013. It features a special section on the 12 facilities that functioned as jails for the Federal Bureau of Prisons. Highlights: From 1999 to 2013, the number of inmates in local jails increased by 21%, from 605,943 to 731,570 [while] During this period, the growth in the jail population was not steady, as the jail confined population peaked in 2008 at 785,533 then declined to its 2013 level; The adult jail incarceration rates changed slightly between midyear 1999 (304 [per 100,000 adult U.S. residents]) and yearend 2013 (310 [per 100,000 adult U.S. residents]); Nearly half (46%) of all local jail inmates were confined in jurisdictions holding 1,000 or more inmates in 2013, down slightly from 50% in 2006; Between 1999 and yearend 2013, the female inmate population increased by 48%, from approximately 68,100 to 100,940. The male inmate population increased by 17%, from approximately 537,800 to 630,620; [and] The juvenile population (persons age 17 or younger) held in adult jail facilities in 2013 (4,420) decreased by more than half from its peak in 1999 (9,458).
"Key Statistics provides easy access to trend data from BJS's [Bureau of Justice Statistic's] data collections.

"This dynamic analysis tool allows you to examine data collected by the Annual Parole Survey on persons sentenced as adults. It includes parolees who were conditionally released to parole supervision by parole board decision, by mandatory conditional release, through other types of post-custody conditional supervision, or as the result of a sentence to a term of supervised release. You can create Custom Tables of the number, characteristics and supervision rates of adults on parole at yearend. This tool also allows you to create custom tables of parole entries and exits." Access is provided to: User's Manual; quick tables; custom tables; methodology; definitions; supporting documents; and FAQs.
“This dynamic analysis tool allows you to examine National Prisoner Statistics (NPS) on inmates under the jurisdiction of both federal and state correctional authorities … The pre-set Quick Tables show you trends in prisoner statistics and provide links to key tables in the most recent BJS publication on the U.S. prisoner population. If you would like more detail, use the Custom Tables to analyze yearend populations, admissions, or releases. You can create custom tables of yearend populations by the number of inmates in custody or under legal jurisdiction, those held in the custody of private facilities and local jails, the imprisonment rate of prisoners sentenced to more than 1 year, and noncitizens and juveniles in prison. You can customize tables of prison admissions or releases by many variables. All custom tables can be analyzed further by the prisoner’s sex.” Access is provided to: User's Manual; quick tables; custom tables; methodology; definitions; supporting documents; and FAQs.
"This dynamic analysis tool allows you to examine data collected by the Annual Probation Survey on adult probationers. It includes all adults, regardless of conviction status, who have been placed under the supervision of a probation agency as part of a court order. (Adults are persons subject to the jurisdiction of an adult court or correctional agency.) You can create Custom Tables of the number on adults on probation at yearend. This tool also allows you to create custom tables of probation entries and exits."

“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.
