Nearly a third of Americans have a record by the time they are 23.
That's according to a study in the latest issue of the journal Pediatrics.
Researchers found just over 30 percent of 23-year-old's say they've been arrested.
That's higher than the 22-percent from a study in 1965.
Analysts used a national sample of adolescents and young adults collected between 1997 and 2008.
The study does not specify racial or regional differences.
