PROPWT is a 16 digit numeric variable.


PROPWT reports the proposed weight used when population and day combined weights need to be rescaled. PROPWT is a corrected version of the original weight. The original weight is adjusted to make sure there is a perfect balance in terms of days of the week. Original weights provided by surveys generally correct for this, so PROPWT should not be very different from the original weight. PROPWT assigns a non-zero value only for good diaries (BADCASE=0 or 5).

Users who are interested in the original weight may refer to OCOMBWT.

This variable is comparable across years and countries when available.

Comparability — France [top]

In 1985, since the original weight is not available, the proposed weight, PROPWT, is created by using the population taken from the National Institute of Statistics and Economic Studies in France.

Comparability — South Africa [top]

In 2000, the computation of PROPWT differs slightly from other surveys; the original population weight first had to be divided by 10,000 (according to the South African data manual).

Comparability — United Kingdom [top]

In 1983, we calculate the weight as the expected percentage (from 1985 census) divided by the actual percentage by gender and age group.

Since some of the records have no age, in the calculation of PROPWT, we used the sum of weigh instead of sum of good case for adjustment.

In 1987, where an adhoc weight is constructed, the MTUS balances the distribution of the sample survey in relation to the age and sex distribution of the national sample. As people aged 62 and older are not representative of people aged 62 and older as a whole, these diarists are 0-weighted using the PROPWT. Users seeking to include all good quality diaries should use the OCOMBWT, but also should be aware that the older diarists in this survey represent only older people who live with people aged 20-61, not the whole population aged 62 and older.
