There has been much debate and research controversy over the factors that influence the decline in juvenile and adult crime arrests. The influencing factors are situational crime prevention, target-hardening techniques, number of repeat offenders, offenders never caught and aging out process (maturation process). Drug involvement, adolescent/parental relationships, and teenage parents are also factors for the percentile of parents involved. With this said, deciphering statistic research can be a daunting task as different variables such as the number of arrests from a single offender to crimes that are non-reported.
