More than half of the states in the country reduced their prison populations in 2018. Tennessee went the other way.

A new report from the Vera Institute of Justice documenting prison populations at the state and federal levels shows that Tennessee is one of 19 states that increased its prison population last year — and one of only eight states in which the prison population reached an all-time high. The report puts Tennessee's incarcerated population at 30,128.

The new data comes during the first term of Gov. Bill Lee, a Republican who has notably made criminal justice reform a more prominent part of his platform than his predecessor, and as recent polls show overwhelming support for reform in the state.

Tennessee's incarceration rate has gone down slightly to 445 per 100,000 people — a 0.7 percent decrease from last year that still leaves the state with the 17th highest rate in the country. But the state's incarceration is still up 0.9 percent from a decade ago.
