Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
PTROTHER indicates whether the respondent mentioned, in response to an open-ended question, some "other" method to make water safe to drink. The meaning of "other" depends on the specific responses included for a given survey.
The information in PTROTHER 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").
