Description
SUPP4WT is an IPUMS NHIS-constructed variable that harmonizes the sampling weights for a select subset of the supplements of the original NHIS public use files. SUPP4WT is used only in cases where other sampling schemes for that survey year are already handled through PERWEIGHT, SAMPWEIGHT, SUPP1WT, SUPP2WT, or SUPP3WT.
For 2012, SUPP4WT is used for the adults and children who completed the Complementary and Alternative Medicine supplement. This includes all sample adults and sample children between the ages of 4 and 17.
