A Matter of Time: The Causes and Consequences of Rising Time Served in America’s Prisons (2017)

"People are spending more time in prison, and the longest prison terms are getting longer.

To better understand long prison terms, we took a new approach to measuring how much time people spend in US prisons. We looked at annual snapshots of prison populations to see how long people had been in prison so far and compared those snapshots over time. This allowed us to include time served by people who are usually overlooked by more traditional methods."
