The data for this Indicator was obtained through the WNC Healthy Impact Initiative from their secondary dataset and from their primary survey as part of a regional Community Health Assessment process. All secondary data sources are heavily vetted to ensure validity. Professional Research Consultants, Inc. (PRC) is the research firm that conducts the survey to collect the primary data. PRC uses random sampling which produces a highly representative sample. To ensure the best representation of the population surveyed, a multi-mode methodology was implemented for the survey. To increase the potential for participation even further, the surveys were completed both through phone calls and in an online internet-based survey format.
