Description

Definition

The woman's weight is an 8 digit variable with 6 implied decimal places. To use the sample weight divide it by 1,000,000 before applying the weighting factor. All sample weights are normalized such that the weighted number of cases is identical to the unweighted number of households when using the full dataset with no selection. This variable should be used to weight all tabulations produced using data from the woman's file (which includes all derived child files). For self-weighting samples, this variable is equal to 1,000,000.

Source of information

Calculated by statisticians after the survey data is collected and keyed, but before recoding occurs. If the result of the woman's interview was incomplete (V015<>1), the weight will be set to zero.
