There are some 2.2 million people behind bars in the United States. That’s more people than there are in all of New Mexico. And there are more jails and prisons than colleges and universities in this country. Still, it can be difficult to grasp the scale of incarceration in America, in part because so many of our jails and prisons are tucked away far from view in rural areas. Josh Begley’s project Prison Map provides a sense of the enormity of it all by giving us a fascinating vantage point from which to view the architecture of incarceration.
