PPI's annual single-snapshot analysis of the US carceral system: 1.9 million people behind bars across federal prisons, state prisons, local jails, immigration detention, juvenile facilities, and military / territorial prisons. Counters the common claim that 'most prisoners are non-violent drug offenders' by breaking down offense categories, and exposes the churn of pre-trial detention in local jails.
Key findings
1.9 million people are incarcerated in the US on any given day
Local jails hold ~600,000 people, most pre-trial, with median stay measured in weeks
The US locks up more people per capita than any other country
