Young people are committing much less crime. Older people are still behaving as badly as before.

The chart presents the research team’s calculation of the arrest rate for three age groups in 1993, 2003 and 2013. In absolute terms, arrests (like crime) are as expected consistently concentrated among the young at each historical time point. But surprisingly, the drop in the arrest rate over time is entirely accounted for by the current generation of young adults, who are busted 23 percent less frequently than prior generations were at their age. Remarkably, despite the national drop in overall crime and arrest rates, the arrest rate among older Americans is higher than it was 20 years ago. This holds for adults ages 40 to 54 (a 9 percent increase) and even more so for adults age 55 and older (a 12 percent increase). The baby boomers, who drove the American crime explosion in their youth, are apparently continuing to outdo prior generations in their late-life criminality.
