Number of People Serving Time in State and Federal Prisons in the US

"At year-end 2018, an estimated 1,465,200 prisoners were under state or federal jurisdiction. This was a decrease of more than 9% from 2009, when the U.S. prison population peaked at 1,615,500, and a decrease of 2% from the 1,489,200 prisoners in 2017 (table 1). State prisoners made up 88% of the total U.S. prison population at year-end 2018 and accounted for 87% of the decline in the total prison population from year-end 2017. Te number of federal prisoners fell by 3,200, from 183,100 in 2017 to 179,900 in 2018. This was the sixth consecutive year that the federal prison population declined. Federal prisoners accounted for
13% of the decline in the total prisoner population from 2017 to 2018 (not shown in tables).

"Thirty-two states showed decreases in their year-end prison populations from 2017 to 2018 (table 2). Four states had declines of at least 2,000 prisoners during that period: New York (down 2,800), Tennessee (down 2,700), California (down 2,400), and Missouri (down 2,200). Twelve states showed increases from 2017 to 2018, with the largest increases in Texas (up 1,100), Indiana (up 850), and Colorado (up 430)."
