From 1973-1974 to 1983-1984, the number of reported break and enter offenses committed against residences rose by 128 percent, and those committed against shops rose by 54 percent. A nationwide 1983 victimization survey indicates that approximately 31 percent of the break and enter offenses involving residences were not reported to the police. The clearance rate for break and enter offenses has been static. Break and enter offenses for which offenders have been apprehended have mostly been committed by male juveniles entering premises through unlocked doors and windows.

The effectiveness of these programs has yet to be determined. 10 data tables and an appendix containing definitions of break and enter offenses in South Australia.
