A Dataset of Household Demographic Characteristics, Income & Expenditure, and Water Use in the Mwanza Region, Tanzania

The survey covered two municipal districts and two out of the six rural districts in Mwanza, including six villages with and six villages without piped water supply. Ten households were randomly selected for face-to-face interviews in each village.

After excluding one household with outlier expenditure data, a total of 119 valid household questionnaires were retained (60 from villages with piped water supply and 59 from villages without piped water supply).The dataset comprises three modules: (1) Household demographic characteristics (household size, number of dependents, and overall education level); (2) Household income and medical expenditure (annual household income, annual medical expenditure, and the share of medical expenditure in total household expenditure); (3) Water use (water treatment methods, and diarrhea incidence).
