Again, in this case, I'm thinking specifically about the long-form census. So I am thinking about the questions pertaining to religion, how much housework you do, and how much time you spend with your kids, those kinds of questions.
I guess the point I'm getting at is that there are all sorts of sayings about statistics, and I won't repeat any of them here, but it all depends on the angle you're looking at. At the micro level, the individual level, when a person gives information voluntarily there is no question that we're going to have more accurate information from that person. When we go to the next level, that incremental group, the 15% to 20%, or maybe it's 25%, of the population that only gives you that information on that long form because they are forced to, I think any reasonable person would look at that and say that information is going to be less accurate on average than the information obtained voluntarily.
Does that make sense?
