Alberta had an estimated 5,029,346 residents as of July 1, 2025.
That could increase to as much as 8,132,600 (+61.7%) by 2050 under the high-growth scenario, 7,220,100 (+43.6%) with medium-growth, or 6,458,700 (+28.4%) under the minimal-growth scenario.
B.C.’s population as of July 2025 was approximately 5.7 million. It is projected to have anywhere between 5.82 million and 7.53 million people by the half-millennium.
Alberta experienced record-breaking population growth in the first half of the 2020’s, at times seeing more than 60,000 additional residents in a single quarter.
