First, I will just clarify one thing. The census remains mandatory. There were 10 questions that people were required by law...and it's those questions that are used to establish the population. So the census itself was mandatory.
The 2011 census, based on information that we have up to now, is looking very good. The response rate to the census was actually higher than in the 2006 census. We had an extraordinary level of cooperation actually from the population. We spent relatively little effort, relative to previous censuses, chasing non-respondents on the census side. So there is a lot of evaluation that still has to happen, including the coverage studies that we've been discussing, before we can form a definitive view. But based on what we know now, things are looking very positive for the 2011 census population.
