Definition

Percentage of adults aged 18 and over who are heavy drinkers: men having more than 14 drinks a week and women more than 7 drinks a week, on average over the past 30 days. Crude prevalence, not age-adjusted.

CDC Behavioral Risk Factor Surveillance System (BRFSS), a telephone survey of adults, crude prevalence. States and DC only: BRFSS publishes the median of the states rather than a national prevalence, so no national value is served. A state that did not meet BRFSS data standards in a year has no value, and CDC withholds estimates from fewer than 50 respondents or with a relative standard error above 0.3. The dataset also publishes 95% confidence intervals. The series starts in 2011, when BRFSS changed its weighting and added cell phones. From 2011 to 2014 (variable _RFDRHV4) BRFSS stated the threshold per day: more than two drinks for men and more than one for women, the same average. Later years use variables _RFDRHV5 to _RFDRHV9.
