    Sampling

    Sampling Procedure

    A multi-stage cluster sampling design was used to produce representative data. Only one participant was selected per selected household.
    Response Rate

    The overall response rate was 70%.
    Weighting

    Analysis weights reflect adjustments for differences in the age-sex composition of the sample population as compared to the target population.

    Different weight variables are available per Step:
    wStep1 - for interview data
    wStep2 - for physical measures
    wStep3 - for biochemical measures
    This allows for differences in the weight calculation for each Step of the survey as the age-sex composition of the respondents to each Step can differ slightly due to refusal or drop out. Additionally, some countries perform subsampling for Step 2 and/or Step 3. When no subsampling is done and response rates do not differ across Steps of the survey, the 3 weight variables will be the same.
