Multiple years of pre- and post-intervention survey data will be collected from cross-sectional samples of adults and youth in each city to assess intervention effects on harmful alcohol use. Multiple years of archival data will also be collected from each city to assess intervention effects on alcohol-related harms such as motor vehicle crashes and fatalities, violence and unintentional injuries. Multi-level analyses will be conducted with data for the total sample of 18 cities and for each pair of cities to determine whether the overall goal of reducing harmful alcohol use by at least 10% is achieved.
