New projections reveal a stark demographic split: Most Middle Eastern populations will surge through 2100, but Iran and Turkey face steady decline. Explore the data and its profound implications.
A Tale of Two Demographic Futures
A striking new visualization reveals a profound demographic divergence underway in the Middle East. While the majority of the region is set for significant population growth throughout the 21st century, two major powers—Iran and Turkey—are projected to see their populations peak and then decline.
This split trajectory, based on 2024 estimates and long-term projections to 2100, will reshape the economic, political, and social landscape of one of the world’s most strategic regions.
The Data: Projected Population Shifts (2024 – 2100)
The figures tell a clear story of growth versus contraction. Below is a breakdown of the key population data and projections for major Middle Eastern nations.
| Country | 2024 Population | 2050 Projection | 2100 Projection | 21st Century Trend |
|---|---|---|---|---|
| Egypt | 107.3 million | → | 205.0 million | Rapid Growth |
| Iraq | 45.5 million | → | 111.7 million | Rapid Growth |
| Yemen | 34.6 million | → | 59.3 million | Continued Growth |
| Saudi Arabia | 37.9 million | → | 50.4 million | Steady Growth |
| Syria | 24.7 million | → | 35.3 million | Growth |
| Oman | 4.7 million | → | 6.2 million | Moderate Growth |
| Turkey | 85.7 million | → | 82.4 million | Decline |
| Iran | 91.6 million | → | 79.9 million | Significant Decline |

The Growth Engines: Egypt and Iraq Lead a Surge
On one side of the divide are nations poised for a population explosion.
-
Egypt stands out, with its population projected to nearly double from 107 million today to over 200 million by 2100. This sustained growth will intensify pressures on the Nile’s resources, infrastructure, and the government’s ability to provide jobs and services.
-
Iraq is projected to see an even more dramatic relative increase, potentially growing from 45.5 million to 111.7 million. This highlights a nation with a very young population today, whose future stability will depend on managing this growth effectively.
-
Other nations like Yemen, Saudi Arabia, and Syria are also set for substantial increases, promising larger domestic markets but also demanding significant economic planning and resource management.
The Shrinking Giants: Why Iran and Turkey Buck the Trend
The declining trajectories of Iran and Turkey are the exceptions that define this new demographic map.
-
Iran’s Significant Decline: Projected to fall from 91.6 million to 79.9 million, Iran is experiencing one of the fastest fertility drops in recorded history. This is largely attributed to successful early family planning programs, urbanization, economic pressures, and increased female education and participation in the workforce.
-
Turkey’s Gradual Contraction: While more moderate, Turkey’s projected decline from 85.7 million to 82.4 million signals a major shift. Like Iran, Turkey has undergone rapid social transformation, with fertility rates in major cities like Istanbul falling well below replacement level.
For both nations, an aging population and a shrinking working-age cohort present looming challenges: strained pension systems, potential labor shortages, and slower economic growth potential.
Regional Implications: Power, Resources, and Migration
This demographic split will have far-reaching consequences:
-
Economic Weight: The economic center of gravity could shift towards the growing, younger populations of Egypt and Iraq, provided they can create sufficient opportunities.
-
Resource Pressures: Massive growth in already water-stressed nations like Egypt and Iraq will escalate tensions over shared rivers and aquifers.
-
Migration Dynamics: Historically, labor has flowed from high-growth nations to richer Gulf states. Future patterns may become more complex, with aging economies like Iran and Turkey potentially needing to attract foreign workers.
-
Geopolitical Influence: A country’s demographic weight is a component of its power. While Iran and Turkey may face internal challenges from aging, their more stable populations could contrast with the youth-bulge challenges facing their growing neighbors.
Conclusion: A Region Reshaped by Numbers
The 21st-century Middle East will be fundamentally reshaped by these opposing population trends. The region will not face a uniform challenge of “overpopulation,” but a dual reality: managing explosive growth in some nations and navigating the complexities of aging and decline in others.
Policymakers across the spectrum will need to craft responsive strategies—whether for creating millions of new jobs, building sustainable cities, or reforming social security systems. Understanding this great demographic divergence is the first step in preparing for the future it will create.
