Prison Math: What are the Costs and Benefits of Leading the World in Locking up Human Beings? (Column‪)‬

IN 2009, according to the Bureau of Justice statistics, there were 1,524,513 prisoners in state and federal prisons. When local jails are included, the total climbs to 2,284,913. These numbers are not just staggering; they are far above those of any other liberal democracy in both absolute and per capita terms. The International Centre for Prison Studies at King's College London calculates that the United States has an incarceration rate of 743 per 100,000 people, compared to 325 in Israel, 217 in Poland, 154 in England and Wales, 96 in France, 71 in Denmark, and 32 in India. America's enormously high incarceration rate is a relatively recent phenomenon. According to a 2010 report from the Center for Economic and Policy Research (CEPR), U.S. incarceration rates between 1880 and 1970 ranged from about 100 to 200 prisoners per 100,000 people. After 1980, however, the inmate population began to grow much more rapidly than the overall population, climbing from about 220 per 100,000 in 1980 to 458 in 1990, 683 in 2000, and 753 in 2008.
