3 scenarios.. How can immigration shape America’s future? | policy

While the United States was founded as a “nation of immigrants,” in the famous historical expression of former President John Kennedy in 1963, this concept is today undergoing a radical turning point that is reshaping the country’s identity and its economic and demographic future.

With the administration of current President Donald Trump adopting strict mass deportation policies, immigration rates are witnessing an unprecedented sharp decline, which puts the United States before a real dilemma that oscillates between the desire to control borders and fears of an aging population and a shrinking workforce.

A team of researchers believes, according to the American magazine, that immigration represents a fundamental pillar for maintaining population growth, renewing the labor market, and financing social welfare systems, while others confirm that its impact in reducing aging is limited, and that the priority should be for more selective immigration that attracts highly skilled people.

In fact, the United States is witnessing one of the most polarized periods regarding the immigration issue, and a report in the magazine monitors 3 possible scenarios for the country’s future, based on various demographic studies, which place immigration at the heart of the equation of population growth, the labor market, the economy, demographics, and even the future of American politics.

The report presents two conflicting views: the first believes that continued immigration is necessary to prevent the aging of American society, and the second considers that its positive effects on the labor market are exaggerated, while increasing pressure on public services.

According to official data and analyses, the flow of migrants has witnessed a dramatic decline as a result of deportations and a general climate that has become described as excluding migrants.

The US administration announced that within just 12 months of Trump’s inauguration, about 3 million irregular immigrants left the country, voluntarily or through forced deportation.

Brookings Institute estimates indicate that the United States recorded negative net immigration last year, meaning that the number of departures exceeded the number of arrivals, for the first time in at least a decade.

Projections for 2026 indicate that this decline may deepen, and US Census Bureau data confirmed this decline, as net international migration fell from its peak of 2.7 million in 2024 to 1.3 million in 2025, and is expected to collapse to only 321,000 in 2026 if current trends continue.

As a result, US population growth slowed to 0.5%, its lowest level since the Corona pandemic, and with birth and death rates remaining relatively stable compared to the previous year, the sharp decline in net international migration is the main reason for the slow growth rate we are seeing today,” according to Christine Hartley, Assistant Chief of Estimates and Projections at the US Census Bureau.

3 scenarios

In the face of this sharp transformation, demographic experts – led by William Frye of the Brookings Institution and Stephen Camarota of the Center for Immigration Studies – laid out 3 possible scenarios for America’s future based on immigration levels:

• First, the scenario of low or no migration

If there was no immigration at all, the US population would shrink to 312 million by 2051. If immigration was low, the population would grow modestly to 345 million by 2051, or 343 million by 2060, according to other Census Bureau projections.

Expert William Frey believes that the absence of immigration will have a devastating impact, especially since expectations indicate that deaths will begin to exceed births by 2031 in America, accelerating the aging of society and the workforce.

• Second, the medium migration scenario

According to this scenario, which Camarota adopts as a realistic option, the population of the United States will grow by 34.6 million people between 2023 and 2060, reaching a total of 364 million people, and the proportion of the working-age population (18-64 years) will decrease from 60.9% to 58%, which is a less severe decline than the low immigration scenario.

• Third, the high migration scenario:

Frye expects the US population to reach 385 million by 2051, while Camarota raises the estimate to 397 million by 2060. This is the only scenario that maintains a US growth trajectory similar to the early 2000s. This trajectory would also maintain America’s youthfulness, adding 17 million children under the age of 15 and an additional 50 million working-age people by 2051.

Sharp division

Experts are sharply divided on the nature of the economic impact of immigrants: while some see them as a lifeline for an aging society, others see them as a burden on social security nets.

Immigration advocates like Frey see immigrants, who are often young and of reproductive age, as a drain on Medicare and Social Security funds that rely on contributions from a young workforce to care for the elderly.

In contrast, Camarota asserts that the role of immigrants in keeping America young is “exaggerated,” as immigrants are also aging, and their fertility rates have declined significantly to converge with natives (the fertility rate for immigrants is 2.19 compared to 1.73 for natives in 2023), according to one study.

Camarota: Migrants are people, and that means they reach all ages. Yes, they increase the number of working age groups, but they also add to the category of the elderly, and they age over time like everyone else.

In addition, this expert argues that the numbers reveal a financial burden, as 53% of immigrant families benefit from social welfare programs directed at low-income people, compared to only 37% of native citizen families.

In this regard, he says: “Immigrants are human beings, and this means that they reach all ages… Yes, they increase the number of the working age group, but they also add to the category of the elderly, and they grow older over time like everyone else.”

Despite the economic dispute, experts agree that immigration is reshaping the racial map of America, since the majority of new immigrants are of Latin and Asian origins, and while the country is expected to witness a decline in the number of white residents in all scenarios, the numbers of Latino citizens will rise in all cases, which means that America is moving towards greater racial diversity, whatever the level of immigration.
