The United States has the highest documented incarceration rate in the world, at 754 per 100,000 (as of 2009). When looking at specific populations within the criminal justice system the growth rates are vastly different. In 1977, there were just slightly more than eleven thousand incarcerated women. By 2004, the number of women under state or federal prison had increased by 757 percent, to more than 111,000, and the percentage of women in prison has increased every year, at roughly double the rate of men, since 2000.
According to the American Civil Liberties Union, "Even when women have minimal or no involvement in the drug trade, they are increasingly caught in the ever-widening net cast by current drug laws, through provisions of the criminal law such as those involving conspiracy, accomplice liability, and constructive possession that expand criminal liability to reach partners, relatives and bystanders."
While traditionally the US Justice system focused its efforts at the front end of the system, by locking people up, it has not exerted an equal effort at the tail end of the system: decreasing the likelihood of reoffending among formerly incarcerated persons ("Emergents"). This is a significant issue because ninety-five percent of prisoners will be released back into the community at some point.
