Codes and Frequencies
Description
For sample adults age 18 and older who have ever quit smoking for one or more days, CSSTOPURP indicates if, the last time the person stopped smoking, she/he did so on purpose. Please see the Universe tab for detailed information about who was asked this question in specific survey years.
Comparability
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.
Changes in survey design (e.g., quarters in which the supplement was collected) may affect raw frequencies, but do not affect comparability of the variable. As always, data users should use the prescribed IPUMS NHIS weights.
