There’s also the difference of tracking density by homes vs population.
A major part of the decrease in central community populations is simply household sizes. Averages of 4-6 are now 2-3. Partially due to empty nesters and widows. Partially due to smaller households in general and less kids in families these days. Partially due to housing stock/preferences of young couples and families…and where we have built great schools, rec centres, and family attracting amenities.
Areas like Lewis estates will likely see populations fall soon as it ages. Areas like Bonnie doon and Grovenor will likely see increases as elderly people leave/pass and new families move in and raise kids.
But densifying the old areas is key too. And duplexes/skinnies/garage suites won’t move the needle much. We need a few apartments in most old suburbs and lots of townhomes to really increase densities to that of new suburbs.
