    Sampling

    Sampling Procedure

    The 2021 Vietnam COVID-19 High Frequency Phone Survey of Households (VHFPS) uses a nationally representative household survey from 2018 as the sampling frame. The 2018 baseline survey includes 46,980 households from 3132 communes (about 25% of total communes in Vietnam). In each commune, one EA is randomly selected and then 15 households are randomly selected in each EA for interview. We use the large module of to select the households for official interview of the VHFPS survey and the small module households as reserve for replacement.

    After data processing, the final sample size for Round 6 is 3,938 households.

    Weighting

    The main steps for weight adjustment to ensure national and regional representativeness are:
    (1) Start with base weights from 2018 survey
    (2) HH selection and non-response adjustment using propensity score and probability of selection correction.
    (3) Post-stratification: Rescale weights to match national, region, urban/rural populations based on the 2019 population census.
    (4) Trim weights
