According to Reuters, as of 2009, one in every 31 US adults is part of the us prison system, including anything from probation all the way up to jail. This is twice as high as it was 25 years ago, and currently the US has the largest prison population in the world. Also, it doesn't help that prisoners are committing crimes soon after they get released only to be imprisoned again.
