“Through this work, I have a deep understanding of prisons, but I am not a proponent of using mass incarceration to “cure” society’s ills. I have found that incarcerating people rarely addresses underlying causes and conditions such as poverty, trauma, addiction and mental illness. Much more often, it compounds them.”
Christopher Poulos, author of What I learned visiting Alaska’s only maximum-security prison

This project identifies and characterizes prison facilities in the United States. Most or all federal, state, county, tribal, and military prisons are already in our database, and we're identifying which of these are used as immigration (ICE) holding facilities. Private prisons are shown regardless of whether the inmates are there because of federal or state convictions, juvenile detention, or immigration cases.

A small portion of the roughly 1600 facilities that have been used by ICE to house people in immigration-related cases are shown here. We're adding the rest as we have the resources.

You can help in one of two ways:

  1. Volunteer to help collect data.
  2. Donate to our non-profit projects

These buttons take you to the project's results so far.
