This came up before and it is interesting how dismissive and defensive people were. The numbers were only part year, but the trend was obvious.

It is very important that this trend precedes COVID, because it is not a COVID restricted phenomenon. COVID just accelerated it.
The city is now confirmed to have lost a total of over 40,000 people in net domestic migration in the last two years. Note that these stats don't include births or international migration, where the city nets about 6-8,000 per year, but that is clearly not enough to offset.
It is telling that no one is changing their perspective as a result. Which means that everything people are saying about "smart growth" is not data driven, but more exactly what most people expect. A confluence of policies supporting enriching developers with a nanny state philosophy.
Unfortunately, attitudes take a long time to change. So expect the situation to get obviously worse and hit rock bottom before things can get better.
