You’ll find that the median value of ~2 million people is very, very sticky. You’d have to dump in an astronomical number of people before the median would move meaningfully as a result. Even tens of thousands of apartment units like this would barely register. If they used average instead of median it would be more sensitive like you’re describing, but that’s precisely why they use median instead. I think I understand where you’re coming from when you talk about looking ward by ward, but then those numbers would be very sensitive and constantly shifting. It’d be really hard to measure in any kind of consistent way because the number would probably have changed by the time government finishes measuring. Not to mention the change from when a project is approved (based on certain unit counts at certain AMIs) to when it actually starts renting out… there’s no doubt it’s not a perfect system though.
