Number of People in Jails in the US, 2015, by Gender

"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)."
