Prisons try to adjust as their inmate population grows older

The number of elderly Americans serving time in prison has skyrocketed in recent decades. In 1991, for example, just 3% of the men and women behind bars in state and federal prisons were 55 or older. Over the course of three decades, that percentage of elderly prisoners has grown to 15%. That's led to climbing costs for prisons as they deal with the more advanced medical needs of the incarcerated. Sarah Lehr of Wisconsin Public Radio reports.
