Methodology and full results

Data on the proportion of adults who currently use e-cigarettes comes from the Centers for Disease and Control Prevention SMART Survey (Selected Metropolitan Area Risk Trends) conducted in 2017 and it is based on more than 400,000 interviews nationally. The growth in e-cigarette use was calculated as the percentage change between 2017 and 2016, which also came from the SMART survey. The SMART survey also contains information on the rates of depression by metropolitan area.

Demographic data is from the U.S. Census Bureau American Community Survey 1-Year Estimates. Furthermore, statistics on middle and high school tobacco use are from the Center for Disease Control and Prevention National Youth Tobacco Survey. This survey does not contain information about the adult population.
