We already know that when it comes to incarceration, the United States is truly exceptional. As the Prison Policy Initiative has reported previously, the United States incarcerates 716 people for every 100,000 residents, more than any other country. Worldwide, and within the U.S., the vast majority of those incarcerated are men. As a result, women’s incarceration rates are overshadowed and often lost in the data. As a first step in documenting how women fare in the world’s carceral landscape, this 2015 report compares the incarceration rates for women of each U.S. state with the equivalent rates for countries around the world.
