This site was created at the Center for Human Resource Research (CHRR) at The Ohio State University to commemorate the 50th anniversary of the National Longitudinal Surveys (NLS). The NLS is a program of the U.S. Bureau of Labor Statistics. CHRR has conducted the NLS since the program began in 1965, in partnership with the U.S. Census Bureau (from 1965 to 2003) and NORC at the University of Chicago (from 1978 to the present).
