From Prison Policy Initiative:
We’re often asked what percent of the U.S. population is behind bars. The answer: About 0.7% of the United States is currently in a federal or state prison or local jail. If this number seems unworthy of the term “mass incarceration,” consider that 0.7% is just shy of 1%, or one out of a hundred. And a little more context shows that this fraction is actually incredibly high.
Because talking about portions of a percentage can be confusing, this concept is more often expressed as a rate: The United States currently incarcerates 698 per 100,000 people. (The rate is out of 100,000, rather than 1,000 or 10,000, because back when incarceration was much rarer you needed a larger denominator to express the rate in whole numbers. But either way, these are all different ways of expressing the same percentage.)
In some ways, though, looking at the portion of a country that is incarcerated understates the sheer size of mass incarceration, because the denominator includes many groups that are infrequently incarcerated. For example, no toddlers, few adolescents, and not very many teenagers are incarcerated. Continue reading >>>
