Description

For sample persons age 17 and older in 1978-1980, and sample persons age 18 and older in 1990-1992 who were current smokers and ever tried to quit smoking, CSOFFNO reports a number of units associated with a time period reported in a separate variable. Together, these two variables indicate the amount of time the respondent stayed off cigarettes the last time they stopped smoking or during their most recent serious attempt to quit. Users should combine CSOFFNO with CSOFFTP to determine the amount of time the person stopped smoking cigarettes. Please see the Universe tab for changes in universe between samples.

Comparability

The differences in universe described in the Universe tab impact the comparability of this variable over time.

In 1978 1980, and 1992, this question was not asked in all quarters of the survey. Changes in survey design such as these affect raw frequencies but do not affect comparability between samples. As always, data users should apply prescribed IPUMS NHIS weights.
