Data were drawn from the pooled 2000, 2005 and 2010 U.S. National Alcohol Surveys (NAS). These surveys provide comprehensive data on alcohol consumption for residents of all 50 U.S. states and the District of Columbia. Data were collected using random digit dialing (RDD) strategies to sample from the non-institutionalized population ages 18 and older. Computer-assisted telephone interviews were conducted using landline telephones in 2000 and 2005, and both landline and cellular telephones in 2010. The surveys included targeted oversamples of Black and Hispanic respondents, and interviews were conducted in either English or Spanish. An introductory consent script was used, with the requirement for written proof of consent waived by the relevant Institutional Review Boards. Data were weighted to be population-representative at the time of data collection. More details on NAS methodology can be found elsewhere (Kerr, Mulia, & Zemore, 2014).
