Calgary’s growth ring
Calgary remained the region’s population centre, but the fastest growth from 2016 to 2021 unfolded in communities beyond the city limits.
Calgary added 67,564 residents between the 2016 and 2021 censuses. Yet percentage growth was faster in several municipalities around it, as housing and population pushed outward along the metropolitan edge.
The city reached 1.31 million residents in 2021, an increase of 5.5 per cent. Cochrane and Airdrie grew at roughly four times that rate. Reading the region requires both measures: Calgary supplied most of the new residents, while its neighbours changed more quickly relative to their size.

The strongest rates were west and north
Cochrane led the five municipalities, growing 24.5 per cent to 32,199 residents. Airdrie followed at 20.3 per cent, reaching 74,100. Chestermere grew 11.4 per cent, while Okotoks increased 4.8 per cent and passed 30,000 residents.
Percentage change highlights the speed of transformation in smaller municipalities. Absolute growth tells a different story: Calgary still added far more people than any neighbour.

Municipal borders do not contain regional growth
Commuting, housing and infrastructure connect these municipalities to Calgary even when local governments and census boundaries divide them. Faster growth at the edge increases the importance of regional decisions about transportation, water service and land use.
The next census will show whether that outward momentum persisted. The 2021 results already make one point clear: Calgary’s growth story extends well beyond Calgary itself.
Data & Methodology
Population counts and percentage changes come from Statistics Canada’s Focus on Geography Series for the Calgary census metropolitan area. We selected Calgary and four nearby census subdivisions for a concise regional comparison. Statistics Canada’s revised 2016 count is used for Okotoks.
The map uses approximate municipal-centre positions for orientation; it does not depict legal boundaries. Rates are Statistics Canada’s percentage change between census counts and are rounded to one decimal place.
