During the same period, the number of state prisoners age 55 or older Sentenced state prisoners increased 400%, from 3% of the total state prison population 1,000,000 in 1993 to 10% in 2013 (figure 1). Between 1993 and 2003, 800,000 the majority of the growth occurred among prisoners 39 or younger ages 40 to 54, while the number of those age 55 or older 600,000 increased faster from 2003 to 2013. In 1993, the median age 40–54 of prisoners was 30; by 2013, the median age was 36.
