The 10 Most Populous Cities in the World in 1950 Compared to Today

The 10 Most Populous Cities in the World in 1950 Compared to Today

If you're curious which were the most populous cities in the world in 1950—and how it compares to the list today—we've compiled that information for you. Some major metropolises around the world make the list in both eras, but overall, there's been a pretty significant shift in the leading global population centers over 70 years. It's interesting to note—to Americans, at least—that the US had the world's most populous city in 1950, and two cities in the top 10 most populous cities in the world in 1950. However, today, the US doesn't have a city that even comes close to cracking the top 10. New York, its biggest city, ranks 44th today.
