As is likely expected, populations with criminal records generally have lower income than their counterparts. Incarcerated men had incomes about half of those of those who have never gone to prison. And this is controlled for age, reflecting men in the upper 20s to low 40s. Poor people are overrepresented greatly among incarcerated populations. And coming from poorer backgrounds, often these individuals have had little exposure to healthcare, and will have great difficulty finding employment, housing, and aid once released.
