The problem with these figure is they compare city and suburban but city is not just downtown but the whole city.
Downtown/inner city areas of major Canadian cities are doing quite well and are experiencing high growth rates but other parts of the city itself maybe losing population due to demographic changes.
All those suburab houses of the 1990/70s that were still in the city proper has M&D and 4 kids but now M&D are the only ones left.
I will use my family as an example..................when we were growing up there were 6 in the family all in one house.
My sister was the only one of the 4 of us kids that had a kid of her own. Now there are 7 of us but we occupy 5 different residences.
