Title: The National Longitudinal Study of the High School Class of 1972 (NLS-72) Fifth Follow-Up (1986) Sample Design Report
Description: This report is the methodology report for the National Longiitudinal Study of the High School Class of 1972 follow-up in 1986. Chapter 2 summarizes the base year sample selection procedures and describes in detail the selection procedures for the fifth follow-up survey. Chapter 3 describes the calculation of sample case weights that adjust for differential probabilities of selection and for nonresponse within weighting cells. In order to provide full technical information, the nonresponse adjustment factors for all weighting cells are included in appendix A. Chapter 4 examines the possible impact of survey nonresponse, a potential source of bias. The amount of bias depends on the proportion of nonrespondents and the magnitude of any difference between respondents- and nonrespondents on variables of interest. Chapter 4 presents a description of nonresponse rates among various subclasses of the fifth follow-up sample. Chapter 5 describes procedures for computing sampling errors and design effects. The NLS-72 sample, because it is a clustered, stratified, and disproportionately allocated sample, presents some special difficulties in estimating actual sampling errors. Chapter 5 discusses the approach NORC has taken to this problem. Sampling errors and design effects are presented for a set of proportions for the entire sample and for important domains or subgroups. Finally, several "rules of thumb" are offered for estimating standard errors under various circumstances.
