Hi, I am including Sample Adult component and other variables which have different WEIGHT. For instance, there are two different WEIGHT variables i.e., PERWEIGHT and SAMPWEIGHT. In this situation, should I just consider SAMPWEIGHT or PERWEIGHT or both? If both, how can I adjust sampling weight in my analysis?

In general, you should use the sampling weight that defines the smallest subset of the data included in your calculations. Said differently, if you include variables that are part of the sample adult component of the survey, your sample will not include individuals who are omitted from the sample adult component of the survey. Therefore, you should use the SAMPWEIGHT variable in this case.

Thank you Jeff!
