I just skimmed the article and found no (re-?)definition of 'arrest'. If it's 40% for the general population and the arrest rate is a function of economic class, the rate for the lower class would have to account for the significantly smaller rate that I perceive in my middle-class peer group.
Either that or my peers are statistical outliers. I don't think there's any other form of selection going on that would prevent them from being a representative sample of their economic class, though.
The article possibly indicated a loose definition of 'arrest' here, though:
> ...arrested or taken into custody for a nontraffic offense by age 23.
For my definitions of 'arrest' and 'custody', being arrested implies being taken into custody.
