Definition
SALTSOURCE reports where the household got its cooking salt. For many surveys, a sample of the household's cooking salt was tested for iodine levels.
The information in SALTSOURCE is taken from the household record and applies to regular household residents, not temporary visitors. Researchers may wish to exclude visitors using the RESIDENT variable (with visitors coded "2") when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
