For sample adults age 18 and older who are current smokers or who were regular smokers within the last year, CSSTOPEV indicates if the person ever stopped smoking for one day or longer because she/he was trying to quit smoking. Please see the Universe tab for detailed information about who was asked this question in specific survey years. Please see the Comparability tab for information on slight changes in question wording between years.
In 1991 and 1992, the question asked "have you ever stopped smoking for one day or longer." In 2000 forward, the question specifically asked "have you ever stopped smoking for one day or longer because you were trying to quit smoking."
There are minor changes in the universe statement between years, as outlined in the Universe tab, which impact the comparability of this variable over time. Users are advised to consider the impact that changes in the universe may have on their analyses when using data from multiple years.
