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.
Second non-bio child born in the US
|IFSS_OKBORNUS_1, IFSS_OKBORNUS_2, and IFSS_OKBORNUS_3 indicate whether each of the respondent's first three non-biological children was born in the United States.
General Comparability Notes
Summary: The question text remains consistent. 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. However, the universe for the variable is not consistent.
The respondent universes were generally equivalent (the respondent reported having non-biological children that had been under her care). 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 in 1995 who would have been included in 2002.
The universe of children about whom the question was asked is less comparable. In 1995, the question was asked of all non-biological children who had ever lived with the respondent. In 2002, the question was only asked of children were previously unrelated to the respondent in any way and who are currently living with her, and children who were adopted. Concerned analysts can use IFSS_RELOTHKD, IFSS_STILHEROK, and IFSS_ADPTOTKD to restrict the universe in 1995 to create a completely comparable sample.
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.
