A recently published study found youth curfews reduce juvenile arrests. The study, published in The American Law and Economics Review by the University of California, Berkeley, showed arrests of youths were directly impacted by curfews, dropping almost 15 percent in the curfew’s first year and 10 percent in the following years. The report analyzed data from the Federal Bureau of Investigation’s Unified Criminal Reporting files from 1980 to 2004 for 54 large U.S. cities (with populations more than 180,000) that enacted youth curfews between 1985 and 2002. Arrests of young adults outside the curfew restriction also dropped suggesting fewer cross-age interactions, according to the study. A survey in 1996, found 146 of the largest 200 U.S. cities had curfew laws on the books.
