Suppose every federal drug offender were released today. That would cut the incarceration rate to about 693 inmates per 100,000 population. Suppose further that every drug offender in a state prison were also released. That would get the rate down to 625. It’s a significant drop, no question — these hypothetical measures would shrink the overall prison population by about 14 percent. (There isn’t data from BJS on the most serious charges faced by those in local jails, so let’s assume that no jail inmates are released in these scenarios.)But let’s have some international context. Even in that extreme hypothetical situation, the U.S. would still be an incarceration outlier.
