Summary for Variable Group: Adoption and adopted children
This variable group describes the respondent's experience with adoption, including whether she has ever considered adoption, as well as information about the first three children she adopted. This information includes the child's sex, relationship to the respondent, date of birth, Hispanic origin, and race, as well as when the child came to live with the respondent, whether the child still lives with the respondent, and whether the child was born in the U.S.
Third adopted child born in the US
|IFSS_ADKBORNUS_1, IFSS_ADKBORNUS_2, and IFSS_ADKBORNUS_3 indicate whether each of the respondent's first three adopted children was born in the United States.
General Comparability Notes
Summary: This variable is highly comparable across time. In all years, respondents were asked whether the child was born in the United States or in another country, and the answer categories are also the same across studies. There is some inconsistency in universe/focal child such that 1982 and 1988 are exactly comparable but 1995 and 2002 differ. These differences are described below.
The respondent universes were functionally equivalent in the four surveys (the respondent reported having non-biological children that had been under her care and whom she adopted). The differences in the applicability criteria, such as that the respondent had not yet begun her period, are unlikely to result in many women being left out of the question sample who would otherwise have been included. In 1982, women who were never married and never pregnant were also excluded, but given the rarity of single-parent adoptions at that time, it seems reasonable that the overall universe was not significantly changed.
We used the variables ADPTOTKD (2002) and ADPT00 (1995) to determine whether the referenced non-biological child was legally adopted by the respondent and included only those who were to make the answers as comparable to the earlier years as possible. IFSS_ADKIDNUM provides the non-biological child index of the first three adopted children.
We chose to harmonize only the first three adopted children across the studies to keep this variable consistent with the other non-biological children variables.
