For sample adults aged 18 and over, PIPEV indicates if the person ever smoked a pipe. PIPEV is available for persons age 17 and older in 1970, half of sample persons age 18 and older in 1987 and 1992, and sample persons age 18 and older in 1991. For 1970, the question asked if the person smoked "at least 3 packages of pipe tobacco during [their] entire life." Please see the Universe tab for changes in the universe over time for this variable.


From 1970 to 2005, "pipe" was person defined. In 1987, the Field Representative's Manual noted that if questions arise, interviewers should include pipe tobacco only, and cigarette or cigars crumbled into pipes should not be counted. The 2005 and 2015 survey text added the phrase "even one time?" to the question about whether the person ever smoked a pipe. Beginning in 2015, pipe is defined as a pipe filled with tobacco: either a regular pipe, water pipe, or hookah.


Apart from changes in the universe, this variable is mostly comparable for 1987-forward. There was a small change in wording beginning in 2005, in which the question included asked "Have you ever smoked a pipe" and added the phrase, "even one time." Also note that although the definition was made more explicit in 2000 and forward, these definitions were not routinely shared with persons, so the term "pipe" would typically be person-defined in all surveys. In 2015, pipe is defined as a pipe filled with tobacco-either a regular pipe, water pipe, or hookah.

In addition to the different question working in 1970, the use of proxy reporting in 1970 also reduces comparability with all later years. In 1970, a person representing the family (a proxy) could answer the questions associated with PIPEV for all other family members over age 17. As self-report is typically more accurate than proxy report, researchers may want to indicate this caveat when analyzing the data or interpreting results and when comparing 1970 with all later years.

The introduction of a substantially revised questionnaire in 2019 may affect comparability with earlier years. The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
