Thanks for this.
In Moncton's case the inner city areas losing population aren't so much because people are fleeing the city, but more simply because the neighbourhoods are aging and younger families with children are more drawn to the suburban areas (picket fences, schools etc).
Of course, there are some less than desirable central city neighbourhoods where people are fleeing (like Dominion and High), but they are in the minority.
Are you planning on doing a map for Freddy too???
