How the two compare
In 2025 the United Kingdom has 1.67× as many people as Canada: 69.5 million against 41.7 million. The difference is 27.8 million. Canada is 60% the size of the United Kingdom. Together they hold 1.4% of the 8.19 billion counted here.
Then and now
In 1960 the order was the United Kingdom ahead, 52.4 million to 17.9 million, a ratio of 2.93×. Since then the United Kingdom has grown 1.33× and Canada 2.33×, averaging 0.44% and 1.31% a year.
The lines never cross between 1960 and 2050: the United Kingdom stays ahead throughout, and the gap widens by 2050.
Towards 2050
Projected to 2050, the United Kingdom reaches 74.9 million (7.8% more than today) and Canada reaches 46.6 million (11.9% more). By then the ratio is 1.61× in favour of the United Kingdom.
Land and people
Land changes the picture: the United Kingdom has 241,930 km² and 287 people per km², Canada has 8,788,700 km² and 5 per km². The United Kingdom is 60.6× more densely settled.
Behind the totals, fertility is 1.55 in the United Kingdom and 1.25 in Canada; life expectancy is 81.4 against 82.1 years; 19.7% against 20.3% of people are 65 or older. The younger the population, the longer it keeps growing after birth rates fall.
Where the numbers come from
Figures are the World Bank's "Population estimates and projections" series, built from United Nations and national statistics. Values up to 2025 are estimates; 2026–2050 are projections that assume current fertility, mortality and migration trends continue, so they are not forecasts of events such as wars or policy changes. Territories are listed as the World Bank lists them, and a small number of places have gaps in some years.
