Summary for Variable Group: Non-biological children
This variable group provides information on whether the respondent raised her husband/partner's children or other non-biological children, and how many of those children she raised. Additional information is provided for the first three non-biological children who lived with the respondent. This information includes the child's sex, relationship to the respondent, date of birth, Hispanic origin, and race, as well as whether the respondent adopted the child, 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.
Century month of first non-bio child's birth
|IFSS_CMOKDDOB_1, IFSS_CMOKDDOB_2, and IFSS_CMOKDDOB_3 give the first three non-biological children's birthdays in century months.
General Comparability Notes
Summary: Century month of the child's birth was obtained by asking either for the child's actual date of birth or for the month and year of the child's birth - those dates were then converted to century months. Instructions direct the interviewer to probe for a season when a month is not known.
The respondent universes for these variables were functionally equivalent (the respondent reported having non-biological children that had been under her care). The only differences in the applicability criteria, such as that the respondent had not yet begun her period or that she had never been married and never pregnant, are unlikely to result in many, if any, women being left out of the question sample who would have been included otherwise.
The universe of children to whom the question applies varies between years. In 1995, the question was asked of all non-biological children who ever lived with the respondent. In 2002, however, the child universe was restricted to only non-biological children who currently live with or were adopted by the respondent. This change in universe could pose analytical problems; concerned analysts can use IFSS_STILHEROK and IFSS_ADPTOTKD to determine which children were still in the household and/or adopted to create entirely comparable universes.
We chose to harmonize only the first three non-biological children across the studies to keep this variable consistent with the other non-biological children variables.
