It’s the Demographics, Stupid: Why the U.S. Needs Immigration to Maintain Economic Vitality

As rivals like China and Russia face demographic decline, America can maintain its edge—if we act on immigration now.

America’s economic engine is running low on fuel, and the issue isn’t inflation or interest rates, but people. Birthrates are falling, the workforce is aging, and unless we tap immigration as a strategic advantage, we risk stalling out in a world racing ahead.

In his essay The Age of Depopulation, Nicholas Eberstadt, one of the country’s foremost policy thinkers, warns that we are living through an unprecedented population crisis, one not brought about by the horrors of war or the scourge of disease, but by choice. In country after country, people are deciding to have fewer children, and it’s changing everything.

Eberstadt, who holds the Henry Wendt Chair in Political Economy at the American Enterprise Institute, warns this is no distant crisis. The U.S. is already in the thick of it. Our birth rate has been in a freefall, now sitting at a worrying 1.6 children per woman, far below the replacement rate of 2.1 needed to maintain population stability (CDC 2025).

Without more babies we’ll face the economic consequences of fewer workers supporting more retirees, social systems buckling under the strain, and a country that’s aging faster than we can handle.

Eberstadt doesn’t just spotlight the problem; he outlines a lifeline: immigration. A growing body of research from the Brookings Institution, Pew Research Center, and the National Academies of Sciences echoes his argument. These organizations have all underscored immigration’s role as a demographic and economic stabilizer in the face of declining birth rates and an aging workforce. Rather than casting immigration as a burden, he sees it as the tool that could keep America competitive as others falter.

While some U.S. leaders champion barriers and bans, the real threat to our future isn’t who’s coming in, it’s who might stop wanting to.

Immigration isn’t a weakness. It’s our last demographic advantage.

America’s Demographic Dilemma

Let’s look at the numbers. It’s not just that people are having fewer babies; it’s that this drop in birthrate is happening at the same time our population is aging. And as the working-age population shrinks, who’s left to power our economy? Eberstadt is not alone in this premise.

The Pew Research Center backs Eberstadt up, predicting that immigrants and their children will account for 88% of U.S. population growth through 2065 (Pew Research Center 2015).

That’s a stunning statistic. It means that without immigration, America’s demographic outlook would be bleak indeed, a shadow of the vibrant, growing nation we’ve long considered ourselves to be.

Now, you’d think the economic case for immigration would be obvious. The U.S. Chamber of Commerce certainly thinks so. They’ve pointed out that critical sectors like technology, agriculture, and healthcare are already experiencing severe labor shortages (U.S. Chamber 2023). Immigration, they argue, is the practical solution. Expand work visas, streamline the green card process, and establish a clear path to citizenship for undocumented workers who are already contributing to the economy.

Yet immigration, in all its complexity, has become a political football. A solution so obvious is entangled in ideological warfare. However, here’s the reality: without immigrants to replenish our workforce, drive innovation, and power the care economy, we risk following the path of Japan or Italy, countries grappling with demographic decline, a shrinking labor force, and slow economic growth.

While some critics argue that immigration depresses wages or strains public services, evidence from the National Academies of Sciences, Engineering, and Medicine shows otherwise. Their comprehensive 2017 report concluded that immigrants and their descendants make positive long-term fiscal contributions, particularly at the federal level (National Academies 2017). Immigration, then, is not a liability but a strategic asset.

Rivals in Demographic Decline

Eberstadt paints a global picture of demographic decline, one that includes some of America’s biggest geopolitical competitors. Russia, for example, has been in sustained demographic decline for decades, its low birthrate compounded by high mortality and outward migration. China, still a global economic force, is now confronting the demographic drag created by decades of its one-child policy. The United Nations projects that China’s population will peak in the next decade and then start its inevitable decline. Iran and North Korea, with their secretive regimes, are also facing similarly bleak demographic futures.

This isn’t just about fewer people—it’s about power. As these nations lose people, they also lose their ability to project economic and military strength. For the U.S., this is a strategic opportunity.

By embracing immigration and staying demographically vital, the U.S. can remain a global leader, even as others falter.

The Shrinking Family and the Care Economy

Eberstadt also points to another shift: the retreat of the family as a central economic unit. In decades past, families were large and multigenerational, providing a built-in safety net for both the young and the old. Today, families are smaller, and many people are choosing to live alone. That leaves more Americans reliant on public services, especially in old age.

As family caregiving capacity shrinks, public institutions must fill the gap, particularly in elder care. Here again, immigrants play a vital role. They serve as frontline caregivers in nursing homes, hospitals, and homes across the country.

Africa’s Exception—and Its Challenges

One part of the world stands apart from the narrative of demographic decline: sub-Saharan Africa. There, birth rates remain high, and the population is expected to double by 2050. On the surface, this sounds like a potential workforce bonanza. But, as Eberstadt is quick to point out, it’s not that simple. The World Bank reports that the literacy rate in sub-Saharan Africa hovers around 70%, a figure that may seem reasonable at first glance, but masks a deeper crisis. Many children fail to meet basic reading and math proficiency levels, especially in rural areas, where access to quality education is severely limited (World Bank 2022). Without massive investments in education and infrastructure, Africa’s demographic advantage could become a liability.

Still, there’s hope. Developed nations, including the U.S., could partner with African countries to harness this potential.

With the right investment, sub-Saharan Africa’s youthful population can become a valuable asset to the global economy.

Why AI Isn’t Enough

Eberstadt also considers whether technology might save us. Artificial intelligence, he argues, could help mitigate some of the economic challenges associated with a shrinking workforce. Historically, technological advancements have helped societies overcome labor shortages, and AI could do the same.

But there’s a limit. AI can take over repetitive tasks, but it can’t replace caregiving, creativity, or entrepreneurship. Immigration remains essential.

Technology alone won’t save us, but combined with smart immigration policy, it might just keep our economy strong.

The Immigration Math

Recent projections reinforce these demographic realities. According to a Brookings analysis of new Census Bureau projections, immigration is now a crucial component of U.S. population growth. Without sustained immigration levels, the U.S. is expected to experience a decline in population by 2060, particularly among the working-age segment (Brookings, 2023). Since 2000, the U.S. has seen shifting immigration patterns. Legal immigration has remained relatively stable, while unauthorized immigration has fluctuated, peaking around 2007 before declining slightly. Despite annual inflows, the total unauthorized immigrant population has hovered between 10.5 and 12 million for two decades.

While public concern has spiked in recent years, the data does not show a recent explosion in the total number of unauthorized immigrants. Instead, population turnover, through deportations, voluntary returns, and status adjustments, has kept overall levels relatively stable (Pew Research Center 2024, Migration Policy Institute 2024).

A Call to Modernize Immigration Policy

At the end of the day, the U.S. has a choice to make. Do we ignore the demographic warning signs and hope that we can weather the storm with our dwindling population, or do we embrace immigration as the lifeline it is? According to the Brookings Institution, immigrants aren’t just crucial to the economy—they’re critical to sustaining the care sector, especially as our aging population increases the demand for caregiving services (Brookings Institution 2023).

Congress doesn’t need to invent new solutions, it needs to enact existing ones.

Proven policy tools, such as expanded high-skill visas, earned legalization, and family reunification pathways, are on the table. What’s missing is urgency.

Eberstadt has laid out the case. The question is whether we will listen.

We’ve built walls, cut legal pathways, and sent the message that newcomers aren’t welcome. However, in doing so, we’ve risked not only our moral leadership but also our economic future. If America no longer looks like the land of opportunity, fewer people will choose it—and we can’t afford that.

It’s the demographics, stupid. And if we fail to embrace the necessary changes, the consequences will be more than just economic, they’ll shape the future of America as we know it.
