Original Cohorts Data Overview

The NLS were begun in the mid-1960s with the drawing of four samples of men and women. Surveys of the four Original Cohorts have, over the years, collected two basic types of information: (1) Core data on each respondent's work experience, education and training, family income, household composition, marital status, and health; (2) Supplementary data specific to the age, sex, and stage of life or labor market attachment of each cohort.

National Longitudinal Survey of Mature and Young Women (NLSW)

The National Longitudinal Survey of Mature and Young Women, a two-cohort survey, is part of the NLS Original Cohort project. The Mature Women's cohort includes 5,083 women who were ages 30-44 when first interviewed in 1967, while the Young Women's cohort includes 5,159 women who were ages 14-24 when first interviewed in 1968. Data for both cohorts are available through 2003, when active surveying was discontinued.

National Longitudinal Survey of Older and Young Men (NLSM)

The National Longitudinal Survey of Older and Young Men, a two-cohort survey, is part of the NLS Original Cohort project. The Older Men's cohort includes 5,020 men ages 45-59 in 1966, with data available through the 1990 survey year, the final year the Older Men were interviewed.
