Key Concepts About Selecting the Correct Weight in NHANES

To produce estimates appropriately adjusted for survey non-response it is important to check all of the variables in your analysis and select the weight of the smallest analysis subpopulation.

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.
