Funding Sources for the NLSY97:

The Bureau of Labor Statistics (BLS) provides funding to collect data on youth labor force experiences, investments in education, training, government program participation, and many other topics influenced by labor market behavior.

Other special sets of questions have been funded as indicated:

  1. Various questions in the self-administered portion of the Youth Questionnaire, including questions on health, fertility, and social relationships, have been funded by the National Institute of Child Health and Human Development (NICHD).
