I agree that it makes no sense. Both Orleans and Barrhaven are also separated by non-urbanized land from the central area, but the space for Kanata is "just enough"...

Forget the "population centre" (replaces "large urban") geography. Its an obscure measurement and the reporter somehow came across it and thought it was a proxy for the City of Ottawa. I can't believe though no one looked at the 735,000 figure and thought, yup that sounds right.

The main geographies are CMA, CMA (ON part/QC part), Census Division/Subdivision. Stick with those and you'll be on the same playing field as everyone else.

What's interesting is that the 2015 estimate for Ottawa (City) based on 2011 Census is higher than the unadjusted 2016 Census.

I think that is very likely and a good observation.

What's interesting about that? It's entirely expected.

That 2015 population is higher than 2016 population? The average person would not expect that nor would they know why there is a difference between the two numbers. It's interesting because it reflects the flaw of the process.

It isn't that the 2015 population is higher, it is just that they overestimated population growth before actual numbers came in.

This appears to be a consistent problem. The city is now 50k smaller than the official city projection, which means that staff and council are overestimating demand for services, infrastructure, housing, etc.

Undercoverage is about 3% nationally (don't know what it has been for Ottawa off-hand) consistently every census plus or minus a bit. This is something they know and expect. That is why Statistics Canada considers the population estimates to be the more accurate population figure. Next year the results of the undercoverage surveys will be released which will correct the undercoverage.

There's some tech.gremlin related to the fact that the Ottawa-Gatinea CMA spans two provinces; the programmer is working on a patch.

Other way around; they underestimated the 2016 population by not including the undercount, which for 2006-2011 was 3.2%. The flaw is that people generally aren't aware of the undercount so people take the first Census release as gospel and do not realize the actual population is higher than reported. This never makes it in the media coverage.
