Who is in the sample
The survey does not reach every household. It first selects enumeration areas, called clusters, within each stratum, then a fixed number of households within each cluster. Strata combine subregion with urban or rural residence.

How the survey works
Why weights matter
Some households had a higher chance of selection than others. Weights correct for that, so a sparsely sampled subregion counts for what it represents. Every estimate here is weighted.
Who each number describes
Each indicator has its own denominator. Malaria prevalence covers children 6-59 months who slept in the household the night before and have a valid test. Check the denominator before comparing two numbers.
Refugee settlements
Refugee settlements were sampled separately, with about 20 clusters and their own weights. Their estimates stand beside national figures and are never added into them.
