Thanks Do I understand that right, you want to sample households, and within each quintile of household expenditure, the number of household members among sampled households is supposed to add up to 100? Why would you do that? Why not just taking a random sample of households or a stratified sample with respect to household size, if that is a concern. That way, you would at least have a clear picture of the population you are targeting, whereas in the other case, this picture becomes pretty blurry, no?
