Birth wantedness reports: a look forward and a look back.

A number of checks can be done to assess reliability of attitudinal data pertaining to fertility. We ascertain how births that would be considered unintended, based on Time 1 reports of fertility intentions, are classified by respondents at a second interview after the birth occurred. The 1988 National Survey of Family Growth and a telephone reinterview allow us to identify respondents who initially intended to postpone or stop childbearing, but who then had a birth, and to analyze the reports they gave of the wantedness of the pregnancy leading to the birth. We also examine wantedness responses of women who claimed in 1988 that they intended to conceive within the next few years. Reports are compared across a range of respondent characteristics and circumstances, including changes in marital status since the initial interview. The analysis reveals nontrivial inconsistency between women's stated birth intentions and their reports about the wantedness of subsequent births. Details across subgroups are examined. Results also provide new information about effects of duration since birth on intention reports.
