10. Egypt
Projected Population in 2100: 205 million
Egypt’s current population of 112 million is expected to continue rising, likely reaching 160 million by 2050. Due to improvements in healthcare and high fertility rates, this growth trend is projected to result in a population of 205 million by 2100.
9. Tanzania
Projected Population in 2100: 243 million
Tanzania’s current population of 66 million is expected to reach 128 million by 2050 and further increase to 243 million by 2100. This growth, driven by one of the highest fertility rates globally, presents significant challenges for sustainable development and resource management.
8. Indonesia
Projected Population in 2100: 297 million
Indonesia’s population is projected to peak at 322 million in 2050, up from the current 277 million, before declining to 297 million by 2100 due to decreasing fertility rates.
7. Ethiopia
Projected Population in 2100: 323 million
Ethiopia’s population is expected to keep rising from 126 million in 2023 to 191 million in 2050. Continuing with a fertility rate of 3.92, the population is projected to total 323 million by 2100.
6. United States of America
Projected Population in 2100: 393 million
The USA’s population in 2023 is 339 million and is projected to increase to 390 million by 2050. Subsequently, the growth is expected to stabilize, reaching 393 million by 2100. While the USA’s fertility rate is relatively low, immigration significantly contributes to its population growth.
5. Democratic Republic of Congo
Projected Population in 2100: 430 million
The Democratic Republic of Congo, with a population growth rate of 3.13%, is expected to increase from 202 million in 2023 to 197 million by 2050. The population will then surge to 430 million by 2100 as the youthful demographic structure supports continued expansion.
4. Pakistan
Projected Population in 2100: 486 million
Pakistan’s population, currently at 241 million in 2023, is sustained by a high fertility rate and a youthful demographic. This steady growth is expected to lead to a population of approximately 486 million by 2100, posing significant challenges for resource allocation and infrastructure development.
3. Nigeria
Projected Population in 2100: 545 million
Nigeria, Africa’s most populous country, is undergoing rapid population growth driven by high fertility and declining mortality rates. From the current population of 213 million, it is projected to escalate to 545 million by 2100. The young demographic structure, with a notable proportion under 15, would contribute to this growth.
2. China
Projected Population in 2100: 771 million
China’s population, currently at 1.4 billion, is declining and is expected to be halved to 771 million by 2100. The population is steadily declining due to one of the world’s lowest fertility rates, influenced by decades of the one-child policy, urbanization, and changing societal attitudes toward family and career. However, recent policy shifts to encourage higher birth rates have yet to significantly alter these demographic trends.
1. India
Projected Population in 2100: 1.53 billion
India’s population growth remains high despite a substantial decline in fertility rates in recent decades. The population is projected to slightly decrease to 1.53 billion by 2100, down from 1.65 billion in 2050.
