Definition
WTRALLYR indicates whether the household uses its main source of (drinking) water all year or only part of the year.
The information in WTRALLYR 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.
