National Longitudinal Surveys

NLSY79: Multiple Respondent Households

The NLSY sample design selected as respondents all individuals ages 14-21 who resided in 1978 in a surveyed household. As a result, the 12,686 civilian and military respondents interviewed in 1979 originated from 8,770 unique households; 2,862 households included multiple respondents. The relationship of each civilian youth respondent to other respondents originating from his/her household is identified within the NLSY documentation by a set of variables, e.g., 'Relationship to Youth of 1st through 6th Other Interviewed Youth in R's Household' (R1.50 - R1.61). The variable, 'Household Identification Number' (R1.49), links respondents to the households they occupied at the time of the 1979 interview.

The primary types of relationships that existed between respondents within multiple respondent households at the time the surveys began were those of sibling and spouse. Table 3 presents, for these two relationships, the numbers of respondents and family units available for analysis during the initial survey year and in 1992. As of the 1992 survey, 4,806 respondent members of a sibling pair were interviewed; 2,149 family units (of the 2,448 identified in 1979 as having one or more sibling pairs) had at least one member of the sibling pair interviewed.
