Description

PREGNANTNOW records answers to the question, "Are you currently pregnant?" by female sample adults age 18 to 49 (age 18 to 44 in 1985 and 1990). Beginning in 2019, this question was also asked of female sample adults with a response of "don't know" or "refused" for age. Because the question was only included in the sample adult section of the survey, which limited potential respondents to those age 18 and older, pregnancies in adolescents younger than 18 are not captured by this variable.

Comparability

Aside from changes in the universe, this variable is completely comparable between 2018 and earlier years. Questionnaire design changes introduced in 2019 limit 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.
