Jail Incarceration Rate in the US, 2015

"The jail incarceration rate—the confined population per 100,000 U.S. residents—decreased from a peak in 2006 through 2008 (260 per 100,000) to 230 per 100,000 at midyear 2015. These data are based on midyear counts, which includes the number of inmates held in custody on the last weekday in June. This was the lowest rate since midyear 2000 (220 per 100,000). The adult incarceration rate for persons age 18 or older also declined from a peak of 340 per 100,000 in 2006 through 2008 to about 300 per 100,000 each year since 2013."
