Themoreimportantreasonforthefallincrimerates,manysay,isamuchlesssophisticatedone.Itisafactthatcrimerateshavedroppedastheimprisonmentratesoared.In1997thenationalincarcerationrate,at645per100000peoplewasmorethandoubletheratein1985,andthenumberofinmatesincityandcountyjailsroseby9.4%,almostdoubleitsannualaverageincreasesince1990.Surelysomecriminologistsargue,onesetoffiguresisthecauseoftheother.Itisprecisebecausemorepeoplearebeingsenttoprison,theyclaimthatcrimeratesarefalling.A1993studybytheNationalAcademyofSciencesactuallyconcludedthatthetriplingoftheprisonpopulationbetween1975and1989hadloweredviolentcrimeby10-15%.
