The correlation between new criminality and incarceration (or lack of incarceration) seems strong based on rapidly rising violence.
The imprisonment rate for 2020 represented a decrease of 28% from 2010.
In 2020, the imprisonment rate was the lowest since 1992.
The number of admissions to federal prison (down 19,000) and to state prison (down 211,800) both declined by 40% from 2019 to 2020.
An estimated 2.2 million arrests occurred among the approximately 409,300 persons released from prison per the Bureau of Justice Statistics.
Violent crime, especially urban violent crime, increased substantially for 2020-2021 per the FBI and Gallup.
