Crime

 Married people are far safer to be around in terms of crime,
domestic violence and child abuse

A major UK study found that parental divorce before age 10 was a major predictor of later adolescent delinquency and adult criminality (Farrington, 1990)

Children from broken homes are 9 times more likely to become young offenders, accounting for 70% of all young offenders (YJB, 2002)

Child abuse is far more likely without both married biological parents - 6 times in stepfamilies, 33 times when the mother has a live-in boyfriend, and 20 times even when both biological parents cohabit (Whelan, 1994)

A major Home Office study found that unmarried men & women - single, cohabiting, separated or divorced - were more than twice as likely to experience domestic violence compared to married people (Mirrlees-Black, 1999)
