I was not around for the 09 survey, but I think it all depends on what information you are trying to find out, I mean really I do not care what others make for a yearly income so that question would be out, as far as the car you drive? Its the one that gets you from point A to point B. Sometimes survery companys will try to cover more than what is needed for marketable results to others that have nothing to do with the original survey and this is why you get questions about diving and then what brand of car you drive. I guess I hate interogation surveys and would rather get to the point rather than say how many people live in my household or total household income. So I guess the question is what do you want to find out from this survey?
