One out of every 7 of the nation’s prison inmates is serving a life sentence, according to a report by The Sentencing Project. For Blacks, the proportion of lifers is in 1 in 5. Despite a growing consensus for prison reform, “We see life sentences continue to accumulate,” said senior research analyst, Ashley Nellis. Most people “age out of bad behavior” in their 20s and 30s, “so incarcerating them for decades past that point serves no public safety benefit,” she said.
