Well, on whether the census should be legislated, I think we're trying to get away from an overly detailed prescriptive act, to give the chief statistician more autonomy, while at the same time resetting the relationship between the agency and the government. It is interesting that the decision in 2011 led to such a wide outcry across the country. It brought protests from both public and private organizations, which suggests that there is political content to these decisions and that therefore it's appropriate at the end of the day to have responsibility reside with elected and accountable ministers and the government.
