Sampling
A multi-stage cluster sample of households. One individual within the age range of the survey was selected per household.
54.1% overall, Step 3 (biochemical measures) dropped due to low response rate
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. When no subsampling is done and response rates do not differ across Steps of the survey, the 2 weight variables will be the same.
