Hi Lin-

I'm currently (well, perennially) analyzing some BRFSS data, and came up
with a weighting question.  While most of the questions in the BRFSS ask
about the individual being interviewed, some of them ask about the
household in which that individual lives. 

Certain knowledgable individuals (e.g., Donna Brogan) believe that one
should not use the weights when asking about the household.  This makes
sense to me, as the weights are meant to estimates of the number of
persons with some given condition, but when you ask about the household,
you want an estimte of the number of households.

Anyway, I was wondering what you guys were doing in King County.  Are
you just applying the weights universally, or doing it on a
question-by-question basis.
