🤔 When the World’s 40 Most Populous Countries Will Hit Peak Population

Key Takeaways
- Many of the world’s largest economies have shrinking populations.
- China peaked in 2021 and Japan in 2010.
- The U.S. is not expected to peak this century due to migration into the country
- This data is based on projections made in 2024, and these estimates can change significantly based on births, deaths, and net migration.
