WYSAC is currently in the field with the North Dakota Adult Tobacco Survey (ATS). WYSAC has conducted that survey three times before– in 2009, 2012, and 2015. The survey is conducted using the telephone interview mode of data collection, following strict CDC protocols. The survey uses a dual sampling frame to include both landline and cell phone numbers in proportions to reflect the representation of cell phone only and cell phone mostly households in the geography of interest. The sample is disproportionately stratified by four geographic regions. Over 1600 interviews are collected during each iteration of the survey.
