How are unknown or missing values handled in the DRC interactive data query results?
Unknown values (responses coded as “refused”, “don’t know”, or missing) are not included in the denominator when calculating prevalence estimates and weighted population counts displayed in the results tables. The proportion of unknown values is less than 1% for most of the survey items. In nearly all cases, the exclusion of these values does not affect the prevalence estimates (%) and only marginally affects the weighted population counts (Weighted Est.). Income, race/ethnicity and BMI-for-age are notable exceptions. See the data query documentation under “SAS/SPSS Program Code” for more information.
