The NLS studies consist of complex longitudinal surveys that include multiple nationally representative samples. To account for this complexity, the NLS staff has developed a set of cross-sectional weights for each survey round. These weights serve as a simple method for users to correct the raw data for the complex survey design in a specific year. If you are using data from just one survey year, the weight series provides an accurate adjustment.
If you are using data from multiple survey years, a single set of survey weights is not sufficient for an accurate adjustment. However, a resource is provided to help create a custom set of survey weights that adjust for both the complex survey design and for the use of data from multiple years. To create your customized set of weights, simply choose a cohort of interest, select the years/rounds relevant to your research, and click download. A zip file containing an ASCII data file will be saved to your computer with the custom weight set.
