Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
From the 2008 National Health Interview Survey:
Have you smoked at least 100 cigarettes in your entire life?
[If yes:] Do you now smoke cigarettes everyday, some days, or not at all?
[If everyday or some days:] During the past 12 months, have you stopped smoking for 1 day or longer BECAUSE YOU WERE TRYING TO QUIT SMOKING?
[If not at all:] How long has it been since you quit smoking cigarettes?
Adults are classified as current smokers if they report currently smoking cigarettes "everyday" or "some days".
The methodology counts both successful (currently abstinent less than one year) and failed cessation attempts in the last 12 months.
