The simulated frame every weightflow example draws from: 4,495 persons nested in 1,882 households, in 120 primary sampling units, in 4 regions used as strata. Because the whole population is observed, it supplies the known population totals a calibration step needs, and the true values against which a weighted estimate can be checked.
