General Comparability Notes

Summary: IFSS_BRNOUT indicates whether the respondent was born outside the country, though the method of data collection varies over time. In some years, respondents were asked the question directly; in other years, these data were inferred from the respondent's migration record. The universe is all respondents except in the 1995 NSFG, where the universe is restricted.

Although this variable focuses on identifying the foreign-born, the common denominator among response categories across each of the five IFSS surveys in which this topic was asked is whether the respondent was born in the United States. Users interested in region-specific data within the United States should see IFSS_BRTHPLACE. In 2002, the respondent was asked, "Were you born outside of the United States?" In 1995, respondents were asked a series of questions about their birthplace [Section IA]. If they reported that they have always lived in the place where the interview occurred, or if they lived at the address reported in April 1990 since birth, no further questions were asked. Otherwise, the respondent was asked if she was born outside of the United States. In 1988, respondents were asked, "In what state were you born?" [A4]. Data from this variable were then recoded into geographic regions based on U.S. Census Bureau designations. Additional code values were used for respondents who lived in Puerto Rico and outside of the United States. Each respondent in 1960 was not asked directly where she was born; rather, those who have not lived in the first place reported for all of their lives are asked to list every place they have lived. Page 38 of the original questionnaire included a chart entitled "Respondent's Migration Record," which allowed the interviewer to record the place of birth first and then to include additional locations where the respondent resided before the interview date. The answer provided to the first place the respondent lived is included in variable RES_BPLG. A similar pattern applied in 1955: the respondent was first asked how long they had lived in the place where the interview took place. If she had not lived in that place for her entire life, she was asked in what state or country she was born [Questions 2 and 3 of the Personal Data section of the questionnaire].
