Mr. Lake, the problem every census is that there are many more questions we would like to ask and governments and community groups need in order to plan, and there has to be a trade-off as to what can be included to reach a balance in terms of the appropriate length relative to the appropriate information desired. There are many, many questions that many of us would like answered, that governments at the federal, provincial, and local level and community agencies would feel valuable and could use, that aren't included. The problem is not that we ask superfluous questions; the problem is that there are a lot of questions we can't ask.
My colleague, Michael Ornstein, who works with these data all the time, could elaborate if you'd like.
