2021 Alberta municipal censuses

Alberta has provincial legislation allowing its municipalities to conduct municipal censuses. Municipalities choose to conduct their own censuses for multiple reasons such as to better inform municipal service planning and provision or to simply update their populations since the last federal census.

Alberta began the year of 2021 with 345 municipalities, which decreased to 343 with the dissolutions of Improvement District No. 349 on May 1 and the Village of Hythe on July 1. Of these, the only two municipalities to conduct a municipal census in 2021 were the Town of Blackfalds and the Regional Municipality (RM) of Wood Buffalo.

The RM of Wood Buffalo conducted a shadow population count in 2021. The following presents the results of this count for comparison with its concurrent municipal census results.
