How to interpret HHWT = zero?

Dear all,

I`am working with a multiple countries data. Looking at the HHWT I found many cases where HHWT is equal to zero. How to interpret these cases?

Many thanks,
Fred.

The following note, found on the comparability tab of the HHWT variable, should answer this question. “In several samples, at least some very large households were split into individual records. These households may or may not represent group quarters. A household record is written for each of these individuals. Households created as a result of these divisions have household weights set to zero.”

Many thanks!
