The U.S. has more jails than colleges.
. . .
To put these figures in context, we have slightly more jails and prisons in the U.S. -- 5,000 plus -- than we do degree-granting colleges and universities. In many parts of America, particularly the South, there are more people living in prisons than on college campuses. Cumberland County, Pa. -- population 235,000 -- is home to 41 correctional facilities and 7 colleges. Prisons outnumber colleges 15-to-1 in Lexington County, S.C.
As you can see in the map, states differ in the extent to which they spread their correctional populations out geographically. Florida, Arizona and California stand out as states with sizeable corrections populations in just about every county. States in the midwest, on the other hand, tend to have concentrated populations in just a handful of counties. Prisons tend to leave an unmistakeable mark on the landscape, as artist Josh Begley has documented.
Because of the mix of state, federal and local correctional facilities in each county, it doesn't make sense to express these numbers as a rate -- X prisoners per Y number of adults. The presence of a federal or state facility in a given county will greatly inflate that county's prisoner count relative to the general population. And in many instances, large correctional facilities are located in sparsely populated regions, like Northern New York. In some of these counties, prisons account for 10, 20 or 30 percent of the total population.
