This is a greater number of people than the combined populations of Washington, D.C., Milwaukee, Wisconsin, Denver, Colorado, and Seattle, Washington. The United States’ prison population exceeds that of any other country in the world – including China, a country with over 1.3 billion residents.

In 2007, the states spent over $44 billion on the incarcerated. After adjusting for 2007 dollars, that’s a tin cup-rattling 127 percent increase since 1987. Currently, this works out to almost $19,000 per prisoner per year.

For the same period, the adjusted spending on higher education climbed 21 percent. Due to recent overhauls in financial aid, the United States could send their entire criminal population to Harvard for a four-year degree and still spend less money per prisoner per year. For those currently making less than $180,000 a year, the cost of a Harvard education is $18,000 per person per year.
