"Since 2005, more than 60% of all jail inmates were awaiting court action on a current charge. About 4 in 10 inmates were sentenced offenders or convicted offenders awaiting sentencing. The growth in the overall jail inmate population since 2000 was due to the increase in the unconvicted population. Regardless of conviction status, about 68% of jail inmates in 2015 were held for a felony offense, and the remaining 32% were held for either misdemeanor (27%) or other offenses (5%) (not shown)."

"Non-Hispanic blacks (599 per 100,000 black U.S. residents) had the highest jail incarceration rate at year-end 2016, followed by American Indian or Alaska Natives (359 per 100,000 AIAN residents). Non-Hispanic whites (171 per 100,000 white residents) and Hispanics (185 per 100,000 Hispanic residents) were incarcerated at a similar rate at year-end 2016. Among non-Hispanics in 2016, blacks were incarcerated in jail at a rate 3.5 times that of whites, down from 5.6 times the rate in 2000.
