Tokyo is widely considered the largest city on Earth by population.
While different metrics can be used to define "largest city," population within city limits or metropolitan area is a common measure. Based on population within the city's metropolitan area, Tokyo consistently ranks as number one.
Here's a table showing the top cities by population in 2023:
| Rank | City | Population in 2023 |
|---|---|---|
| 1 | Tokyo | 37,194,105 |
| 2 | Delhi | 32,941,309 |
| 3 | Shanghai | 29,210,808 |
| 4 | Dhaka | 23,209,616 |
It's worth noting that population figures can vary slightly depending on the source and the year. However, Tokyo generally remains at the top of the list. Different organizations might use varying definitions of "city" (e.g., city proper vs. metropolitan area), which can affect the rankings.
Therefore, when asked what the largest city is, Tokyo is usually the most accurate and accepted answer when referencing population size.
