For the first time in 38 years the combined population of prisoners in state prisons has declined. New Mexico was not one of the states that contributed to that decline, though, with a 2.8 percent increase in its state prison population between December 2008 and January 2010. That increase represents 176 state prison inmates.
For the first time since 1972, the overall state prison population dropped by 5,739 to 1,403,091. But at the same time, because the federal prison population increased, the nation’s total prison population increased.
The report by the Pew Center on the States shows that state prison populations dropped in 27 states and grew in 23. The overall state prison population grew roughly at the same rate as the general population prior to 1972, at 105 percent. After 1972, the growth shot up rapidly, growing by 705 percent over four decades. Combined with local incarceration rates, the Pew Center found in 2008 that 1 in 100 adults in the U.S. were living behind bars.
