This article in Mother Jones highlighted the difference in private prisons:
The study points out an important link between inmate age and race. Not only do private prisons house high rates of people of color, they also house low rates of individuals over the age of 50—a subset that is more likely to be white than the general prison population. According to the study, “the states in which the private versus public racial disparities are the most pronounced also happen to be the states in which the private versus public age disparities are most salient.” (California, Mississippi, and Tennessee did not report data on inmate age.)
Private prisons have consistently lower rates of older inmates because they often contractually exempt themselves from housing medically expensive—which often means older—individuals (see excerpts from such exemptions in California, Oklahoma, andVermont), which helps them keep costs low and profits high. This is just another example of the growing private prison industry’s prioritization of profit over rehabilitation, which activists say leads to inferior prison conditions and quotas requiring high levels of incarceration even as crime levels drop. The number of state and federal prisoners housed in private prisonsgrew by 37 percent from 2002 to 2009, reaching 8 percent of all inmates in 2010.
The high rate of incarceration among young people of color is partly due to the war on drugs, which introduced strict sentencing policies and mandatory minimums that havedisproportionately affected non-white communities for the past 40 years. As a result, Bureau of Justice Statistics data shows that in 2009, only 33.2 percent of prisoners under 50 reported as white, as opposed to 44.2 percent of prisoners aged 50 and older.
So when private prisons avoid housing older inmates, they indirectly avoid housing white inmates as well. This may explain how private facilities end up with “a prisoner profile that is far younger and far ‘darker’… than in select counterpart public facilities.”
Private prisons claim to have more efficient practices, and thus lower operating costs, than public facilities. But the data suggest that private prisons don’t save money through efficiency, but by cherry-picking healthy inmates. According to a 2012 ACLU report, it costs $34,135 to house an “average” inmate and $68,270 to house an individual 50 or older. In Oklahoma, for example, the percentage of individuals over 50 in minimum and medium security public prisons is 3.3 times that of equivalent private facilities.
“Given the data, it’s difficult for private prisons to make the claim that they can incarcerate individuals more efficiently than their public counterparts,” Petrella tells Mother Jones. “We need to be comparing apples to apples. If we’re looking at different prisoner profiles, there is no basis to make the claim that private prisons are more efficient than publics.”
