Task 1: How to Select the Correct Weights for NHANES Analysis

You must use the weight of the smallest subpopulation that includes all the variables you want to include in your analysis. To select the correct weight for your analysis, you need to find out in which component of the survey your variables of interest were included.


It is important to check all the variables in your analysis and use the weight of the smallest sample subpopulation, otherwise you will not obtain estimates appropriately adjusted for survey non-response.

All interview and MEC exam weights can be found on the demographic file for the respective survey. Weights for a given component conducted on only a subsample of the original NHANES sample are available on the data file for that particular component.
