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.
PTRCHLORINE indicates whether the respondent said, in response to an open-ended question, that adding Sur'Eau - a sodium hypochlorite solution that disinfects water - to water is something that can be done to make the water safe to drink.
The information in PTRCHLORINE 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").
