Codes and Frequencies
For sample persons age 17 and older in 1978-1980 or age 18 and older in 1991-1992 who ever attempted to quit smoking, CSQTRYYRNO reports the number of times during the past 12 months that the person quit smoking. Please see Universe and Comparability tabs for important information regarding changes in the universe and question wording between years.
In addition to the changes in the universe over time outlined in the Universe tab, there is a change in question wording. In 1978, 1979 and 1980, the question read: "During the past 12 months, that is since (date) a year ago, about how many times would you say you made a fairly serious attempt to stop smoking cigarettes entirely?" In 1991 and 1992, the question read: "How many times during the past 12 months have you quit smoking for one day or longer?"
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.
