Description: Adult smoking prevalence is the estimated % of adults (over 18 years) that currently smoke every day or "most days" and have smoked at least 100 cigarettes in their lifetime. Seven year aggregate data is used. Data shown on the graph indicate the last year of the seven year period.

Target Value is based on the Top US Performers (90th percentile) and potentially changes as data is updated annually.

Source: Annual County Health Rankings data are released in March each year and available at http://www.countyhealthrankings.org

Note: Prior to the 2016 County Health Rankings, up to seven survey years of landline only BRFSS data were aggregated to produce county estimates. However, even with multiple years of data, these did not provide reliable estimates for all counties, particularly those with smaller respondent samples.For the 2016 County Health Rankings, the CDC produced 2014 county estimates using single-year 2014 BRFSS data and a multilevel modeling approach based on respondent answers and their age, sex and race/ethnicity, combined with county-level poverty and county and state level contextual effects.
