A continent in motion.
A common baseline reveals two different paths through the same quarter century.
Population, indexed to 2000 = 100
The observed change
From 2000 to 2025, the U.S. population in this snapshot increased from 282,162,411 to 341,784,857, a change of 21.1%. Canada increased from 30,685,730 to 41,651,653, or 35.7%.
Setting each country’s population to 100 in 2000 removes the difference in starting size. Every later value shows the change relative to that country’s own baseline. It is a comparison of growth, rather than a comparison of total population.
What this does—and does not—explain
These national estimates describe population change. This calculation does not separate births, deaths and migration, and cannot establish why the countries followed different paths. Country-level growth also does not describe individual cities or housing markets.
The calculation
Population index = population in year ÷ population in 2000 × 100. Total growth is (last value − base value) ÷ base value × 100. Only years with a present observation for both countries are used in the table.
