The World's Population Growth: A Surprising Trend
In a world where population dynamics are constantly shifting, some countries are experiencing rapid growth that is set to reshape the global landscape. This visualization highlights the fastest-growing populations, and the findings might just challenge your expectations.
Africa and the Middle East: The Epicenters of Growth
Africa takes the lead with an impressive 16 out of the top 20 fastest-growing populations, while the Middle East follows closely with four. The Democratic Republic of Congo (DRC) is predicted to reach a staggering 225.6 million people by 2047, a significant jump from its current population of 112.8 million.
Contrasting Growth Rates
While America's population growth is relatively slow, taking a whopping 133 years to double, several African and Middle Eastern countries are on a much faster track. For instance, Kinshasa in the DRC is projected to be among the world's most populous cities by 2080, a testament to its rapid growth.

Years to Double: A Quick Glance
Here's a breakdown of the countries with the fastest annual population doubling rates:
| Country | Years to Double | Population (2025) | Region |
| --- | --- | --- | --- |
| Oman | 20 | 5.5M | Middle East |
| Syria | 20 | 25.6M | Middle East |
| Central African Republic | 21 | 5.5M | Africa |

The Middle East's Rapid Growth
Oman and Syria are set to double their populations in just 20 years, an incredibly short timeframe. Overall, the Arab states are projected to double their population in 36 years, driven by an average fertility rate of 3.2 births per woman. Yemen and Afghanistan are not far behind, with doubling rates of 24 and 26 years, respectively.
Africa's Fastest-Growing Populations
The Central African Republic and Somalia are set to reach the doubling milestone in 21 years, making them Africa's fastest-growing populations. Even more remarkably, the DRC, with its current population of 112.8 million, could double by 2047, a growth rate that is hard to ignore.
The Future Landscape: 2100 and Beyond
Looking ahead, the DRC is projected to become the fifth-most populous country by 2100, a significant rise from its 15th position in 2025. Meanwhile, Nigeria is set to join the ranks of the world's largest populations, following India, China, and Pakistan.
