Recommended sample (day) weight removing low quality diaries and missing age or sex


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.


This variable is comparable across years.
