General Comparability Notes

Summary: This variable is highly comparable, with only slight differences in question text.

In both the 2002 and 1995 National Surveys of Family Growth, respondents were given a card listing various medical services, including abortion, and were asked "In the past 12 months have you received (from a doctor or other medical care provider)... an abortion?" The universe in 2002 consists of all women, but the 1995 NSFG excludes women who have never had sex. It is likely that the two universes are functionally identical, however. In both surveys, responses of "yes" and "no" are coded as is. "Refused" responses are preserved and left unimputed.

Because abortions are consistently underreported, especially in face-to-face interviews, one should be cautious in using this variable. (See the "Data Quality" section of the 1995 documentation for a discussion of underreporting on this variable.)
