That's, in fact, a classic example of the real care Statistics Canada takes. It consulted over years. The dilemma was, of course, that the time use survey had the space to ask the 30 or 40 questions that you really need to ask in order to understand time use, and because of the nature of those questions and the need for them, that trade-off was made. That kind of agonizing is done for virtually every question, so that only the vital ones are on the census.
