Definition
TRAQUA indicates whether the respondent said, in response to an open-ended question, that the household usually adds Aquatabs -- self-dissolving tablets whose active ingredient is NaDCC -- or other nonspecific or country-specific purification tablets to make water safer to drink.
The information in TRAQUA is taken from the household record, linked to the record of the woman respondent. This information applies to household residents, not temporary visitors, so researchers may wish to exclude visitors using the RESIDENT variable (with visitors coded "2").
