Incarceration rate
American prisons and jails held 2,299,116 inmates as of June 30, 2007.[12] One in every 31 American adults, or 7.3 million Americans, are in prison, on parole or probation. Approximately one in every 18 men in the United States is behind bars or being monitored. A significantly greater percentage of the American population is in some form of correctional control even though crime rates have declined by about 25 percent from 1988-2008.[13] 70% of prisoners in the United States are non-whites.[14] In recent decades the U.S. has experienced a surge in its prison population, quadrupling since 1980, partially as a result of mandated sentences that came about during the "war on drugs." Violent crime and property crime have declined since the early 1990s.[15]
As of 2004, the three states with the lowest ratio of imprisoned to civilian population are Maine (148 per 100,000), Minnesota (171 per 100,000), and Rhode Island (175 per 100,000). The three states with the highest ratio are Louisiana (816 per 100,000), Texas (694 per 100,000), and Mississippi (669 per 100,000).[16]
Nearly one million of those incarcerated in state and federal prisons, as well as local jails, are serving time for committing non-violent crimes.[17]
In 2002, 93.2% of prisoners were male. About 10.4% of all black males in the United States between the ages of 25 and 29 were sentenced and in prison, compared to 2.4% of Hispanic males and 1.3% of white males.[18]
In 2005, about 1 out of every 136 U.S. residents was incarcerated either in prison or jail.[19] The total amount being 2,320,359, with 1,446,269 in state and federal prisons and 747,529 in local jails.[20]
A 2005 report estimated that 27% of federal prison inmates are noncitizens, convicted of crimes while in the country legally or illegally.[21] However, federal prison inmates are only a 6 percent of the total incarcerated population; noncitizen populations in state and local prisons are more difficult to establish. The World Prison Brief puts the total number of foreign prisoners in all federal, state and local facilities at 5.9%.[3]
The United States has the highest documented per capita rate of incarceration of any country in the world. [3][5]
