The NLSY97 cohort comprises two independent probability samples: a cross-sectional sample and an oversample of black and/or Hispanic or Latino respondents. The cohort was selected using these two samples to meet the survey design requirement of providing sufficient numbers of black and Hispanic or Latino respondents for statistical analysis.
The NLSY97 cohort was selected in two phases. In the first phase, a list of housing units for the cross-sectional sample and the oversample was derived from two independently selected, stratified multistage area probability samples. This ensured an accurate representation of different sections of the population defined by race, income, region, and other factors. In the second phase, subsamples of the eligible persons identified in the first phase were selected for interview.
