Every NLS data release contains a set of cross-sectional weights. Using these weights provides a simple method for users to correct the raw data for the effects of over-sampling, clustering and differential base year participation. Unfortunately, while each series of weights provides an accurate adjustment for any single year, none of the weights provide an accurate method of adjusting multiple years worth of data. The custom weighting program provides the ability to create a set of customized longitudinal weights. These weights improve a researchers’ ability to accurately calculate summary statistics from multiple years of data.
After each field period a set of round specific survey weights are produced. The custom weighting program simply creates a new temporary list of individuals who meet the criteria selected from the custom weighting home page. This list is then weighted as if the individuals had participated in a survey round. The weights for this temporary list are the output of the custom weighting program.
