Definition
TRATSOURCE indicates whether the respondent reported that the household's drinking water was "treated at the source" (e.g., by a central processing plant), when asked what the household usually did to make its drinking water safer. An alternative way of stating this response is that the household did nothing itself, because members believed that the necessary treatment took place elsewhere.
The information in TRATSOURCE 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.
