RECWGHT is a 16-digit numeric variable.
RECWGHT is the recommended sample weight.
This weight accounts for population/sample distribution by age group and sex, provides an even distribution of the days of the week (and corrects for the oversample of parents in the 1999-2001 element of the 1998-2001 combined survey) for good quality diaries.
In RECWGHT, all cases with missing basic information or bad diaries are 0-weighted, and thus are excluded from analysis. Nonetheless, these bad diaries remain in the files so that users who may examine the low-quality cases. For more information about the weights, see the weights section in the AHTUS user guide.
Cases were retained where demographic information exits for a spouse who did not complete a diary to allow users to examine non-response, but these cases were zero-weighted.
