Jail Inmate Population in the US by Gender and by Race/Ethnicity at Yearend 2015

"The juvenile population (those age 17 or younger) in local jails continued to decline in 2015, to fewer than 4,000 inmates (tables 3 and 4). This was down from a peak of about 7,600 juveniles in 2010. Since 2000, at least 8 in 10 juveniles held in local jails were on trial or awaiting trial in adult court.
"While males accounted for at least 85% of the jail population each year since 2000, the female jail population grew from 11% of the total jail population in 2000 to more than 14% in 2013 and 2014. As a result, the female jail incarceration rate increased from about 50 per 100,000 female U.S. residents in 2000 to nearly 70 per 100,000 in 2014. The male incarceration rate remained relatively stable since 2000 (about 400 per 100,000 male U.S. residents) (not shown).
"White inmates accounted for at least 47% of the jail population since 2013, up from 42% in 2000. Conversely, the percentage of black inmates held in local jails declined from about 40% in 2005 to 35% in 2014 and 2015. Hispanics represented about 15% of the jail population in 2014, unchanged since 2000. American Indian and Alaska Native inmates represented a small proportion (about 1%) of the jail population, but their number has nearly doubled since 2000."

The Average Daily Population (ADP) of inmates in US jails in 2015 was 721,300. On December 31, 2015, local jails in the US held 693,300 people, of whom 594,200 were male and 99,100 were female. Juveniles held as adults numbered 3,500, plus an additional 300 juveniles were held as juveniles. Racial demographics were as follows: white, 335,100; black/African-American, 243,400; Latinx, 99,000; American Indian/Alaska native: 8,600; Asian/native Hawaiian/other Pacific islander: 5,800; two or more races: 1,500. Only 258,800 had been convicted of any crime, and had either already been sentenced or were awaiting sentencing. The remaining 434,600 were unconvicted, and awaiting court action on a current charge.
