National Longitudinal Surveys

National Longitudinal Surveys (NLS) are studies initiated by the U.S. Bureau of Labor Statistics to collect data over time from the same group of people. By tracking various aspects of their lives—such as employment, education, and family dynamics—these surveys provide valuable insights into how individuals’ experiences change throughout their lives. The data helps researchers and policymakers understand trends in workforce development, income, and social mobility, ultimately informing decisions that can improve economic policies and social programs.
