    Sampling

    Sampling Procedure

    A cluster sampling design was used to produce representative data for that age range in Gabon. Please refer to page 11-12 of report for further information.
    Response Rate

    The overall response rate was 96.7%
    Weighting

    Analysis weights were calculated by taking the inverse of the probability of selection of each participant. These weights were adjusted 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

    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.
