I came here to post this link to some estimated populations for parts of Halifax for 2024:
https://halifaxpartnership.com/research-strategy/halifax-index/communities/
They estimate that downtown went from 26,627 to 32,882, growing by 23.5% just from 2021-2024, while they put the peninsula as a whole at 85,771. The growth was around 3/4 urban and 1/4 rural (really "exurban", or "fringe suburban").
