Administrative data is the term used for the collection of information through other sources that are not the traditional source. I've heard the Minister say that that was how we used to do it in the past, and that's where we're kind of heading. I don't agree that we will ever get to a point, as the chief statistician has told the select committee, where we would not need censuses. I actually think that's not a goal that we should set, because the snapshot that we get from the widespread stopping and reflecting on where we are, who we are, how we identify, what we earn, how we earn it, where we live, who we live with—all of those sorts of things, I don't think the richness of that data can be got only from administrative data, and I think, in the context of the legislative framework we set, it will be very interesting to see whether or not we get to that point. I don't think we should; I don't think we will. Actually, censuses have been taken for over 2,000 years—I know that from my elementary biblical studies—and I think they'll continue to do so for a long time yet.
