1) Percentages of de jure population that are using various methods to treat drinking water.
2) Percentage of de jure population that are using an appropriate treatment method.
Coverage:
Population base: De jure household population (HR file or PR file)
Time period: Current status at time of survey
Numerators:
1) Number of de jure population (HR file: hv012; PR file: hv201 = 1) by water treatment prior to drinking category:
a) Boil (hv237a = 1)
b) Add bleach or chlorine (hv237b = 1)
c) Strain through cloth (hv237c = 1)
d) Ceramic, sand or other filter (hv237d = 1)
e) Solar disinfection (hv237e = 1)
f) Let it stand and settle (hv237f = 1)
g) Other (hv237g = 1 or hv237h = 1 or hv237j = 1 or hv237k = 1 or hv237x = 1)
h) No treatment (hv237 = 0)
2) Number of de jure population using an appropriate treatment method (hv237a = 1 or hv237b = 1 or hv237d = 1 or hv237e = 1)
Denominator: Number of de jure population (hv012 – see Calculation)
Variables: HR file, PR file.

hv005 |
Household sample weight |
The percentage of de jure population using methods to treat water can be calculated using the HR file and simply weighting the data by the sample weight (hv005/1000000) multiplied by the number of de jure household members (hv012). Alternatively, the PR file can be used, selecting the de jure members (hv102 = 1) and weighting just by the sample weight (hv005/1000000).
Numerator divided by denominator, multiplied by 100.
Population with missing information are included as separate categories.
Respondents may report multiple treatment methods so the sum of treatment may exceed 100.
Appropriate water treatment methods are: boil, add bleach or chlorine, ceramic, sand or other filter, and solar disinfection.
In DHS-8, information on water treatment methods is reported for the de jure population only, according to background characteristics. In DHS-7 and earlier phases, information on water treatment was reported for households and the de jure population, by residence.
