How Immigration Affects Economic Growth and Labor Markets

The Big Picture: Immigration and the U.S. Economy

Immigration has been one of the defining forces behind America’s economic rise, and in 2026, it sits at the center of one of the most consequential policy debates in modern history.

The question of whether immigration is a net economic gain or a net drain has been studied for decades. The verdict from the vast majority of mainstream economists, backed by data from the Congressional Budget Office, the Federal Reserve, and major research institutions, is unambiguous: immigration, on balance, is a net positive for the U.S. economy. It expands the labor force, boosts GDP, fuels innovation, fills critical labor shortages, and generates more in tax revenue than it costs in public services.

But the scale, composition, and management of immigration all matter enormously. The post-pandemic surge in immigration between 2021 and 2024 helped fuel one of the strongest economic recoveries in modern history, but the sharp reversal of that trend under the Trump administration’s 2025 enforcement crackdown is already beginning to show measurable consequences in labor supply, job growth, and economic output forecasts.

This article draws on the most current data from 2025 and 2026 to provide a thorough, nuanced examination of how immigration shapes nearly every dimension of the American economy.

How Immigration Expands the U.S. Labor Force

One of the most direct and measurable impacts of immigration is on labor supply. In 2024, nearly 31 million immigrants were working in the United States, representing 19.2 percent of the entire civilian workforce. Crucially, immigrants participate in the labor force at a significantly higher rate than native-born Americans, with a labor force participation rate of nearly 67 percent compared to roughly 62 percent for U.S.-born workers.

Between 2022 and 2024, the foreign-born labor force grew at an average annual rate of 4 percent, while the native-born labor force expanded at just 1.1 percent annually. That difference was not incidental; it was the structural engine that powered unusually strong job growth and tamed inflation without a deep recession.

The Aging Population Problem

America’s native-born population is aging rapidly. Without sustained immigration, the working-age population would shrink and the ratio of workers to retirees supporting Social Security and Medicare would collapse. A study from the National Foundation of American Policy concluded that without continued net inflows of immigrants, the U.S. working-age population will shrink over the next two decades, and by 2040 the country will have more than 6 million fewer working-age people than it had in 2022.

Immigration is not merely supplementing the labor force; for many sectors and regions, it is sustaining it entirely.

GDP and Economic Output: The Numbers Are Staggering

The correlation between immigration levels and GDP growth is one of the most consistent findings in modern economics, and the numbers from the latest projections are striking.

The Congressional Budget Office projected that the immigration surge that began in 2021 will account for an $8.9 trillion increase in nominal GDP over the 2024 to 2034 period. Of this total, $7.8 trillion is directly attributable to the increase in the size of the working population. In 2023 alone, immigrants generated approximately $1.7 trillion in economic activity.

The CBO also noted that increased immigration would add about 0.2 percentage points to the annual growth rate of real GDP during the 2024 to 2034 period, on top of an estimated baseline growth rate of 2.0 percent. While that number may seem modest, over a decade it compounds into a meaningful difference in national wealth.

Beyond raw output, immigration contributes to GDP through multiple channels simultaneously: it increases the size of the consumer market, boosts demand for housing and retail, drives greater entrepreneurial activity, and expands the tax base that funds public infrastructure. The economic impact is not a single lever but a multiplier effect across the entire system.

Immigration and Wages: A Nuanced Reality

The wage question is where the debate gets most heated, and where the research is most nuanced. The short answer is that immigration’s effect on wages is complex, depends heavily on skill level and local market conditions, and is substantially positive for most native-born workers.

The Research Consensus on Native Wages

Research from Brookings in 2026 found that immigration increases wages for middle-class, native-born workers and those in entry-level careers. The same research found that immigration complements native-born workers, improving their ability to move up the income ladder and transition out of careers where they are more likely to compete with immigrant labor. In other words, when immigrants take lower-skill roles, native workers tend to move into higher-paying supervisory or skilled positions.

Economist Giovanni Peri’s widely cited research found that immigration has only a minimal effect on the wages of U.S.-born workers overall. However, Harvard University’s George Borjas has raised concerns about its negative impact specifically on the low-skilled native labor pool, a view that represents a minority position among economists but one taken seriously in the research literature.

The Surge Effect on Wages (2021-2026)

The CBO found that through 2026, the average wage growth of people in the United States who are not part of the immigration surge is slightly less than it would have been without the surge, because the surge slows the growth of wages of people with 12 or fewer years of education. This is an important finding: the wage compression from a rapid influx of lower-skilled workers is real and measurable, even if modest and temporary.

At the same time, immigrants entering the workforce start out at wages below those of similarly educated native-born workers but converge over time. This wage convergence is a sign of labor market integration rather than permanent displacement.

Innovation, Entrepreneurship, and the Immigrant Advantage

Perhaps the single strongest argument for high-skilled immigration is what it does to American innovation. The data here is remarkable and consistent across decades of research.

A 2026 study published in the Journal of Economics and Management Strategy analyzed 199,000 U.S. firms and found that not only are immigrants more likely than native-born Americans to own businesses, but their firms also display more innovative activities and outcomes. Immigrant-owned firms are particularly more likely to create completely new products, improve previous products, use new processes, and engage in both basic and applied research and development, with substantially higher levels of patents and labor productivity.

The technology sector exemplifies this trend most dramatically. Companies such as Apple, Amazon, Google, and DoorDash, among the 46 percent of 2024 Fortune 500 companies founded by immigrants or their children, collectively employ millions and represent trillions in market value. The H-1B visa program, which brings high-skilled workers in science, technology, engineering, and math (STEM) fields, has been a direct pipeline for this talent.

The Fiscal Impact: What Do Immigrants Cost and Contribute?

The fiscal question, what immigrants cost in public services versus what they contribute in taxes, is politically charged but empirically well-studied. The evidence shows that immigrants, viewed across their full lifetimes and the full scope of their contributions, are net fiscal contributors to the United States.

Tax Revenue and the Federal Deficit

The CBO’s analysis of the post-2021 immigration surge found that it would lower federal deficits by a net $0.9 trillion over the 2024 to 2034 period. The mechanism is straightforward: immigrant workers pay payroll taxes and income taxes that generate substantial federal revenue. The CBO noted that additional wages paid to immigrant workers are a major contributor to the boost in revenues because those wages are subject to both payroll and income taxes.

Empirical evidence indicates that immigrants have historically contributed more in tax revenue than they receive in public benefits, creating a substantial fiscal surplus for the U.S. government over time. This is particularly true of working-age immigrants who are net taxpayers before they reach retirement age.

Social Security and Medicare

Immigration plays a critical role in maintaining the solvency of Social Security and Medicare. As native-born baby boomers retire in unprecedented numbers, the worker-to-retiree ratio supporting these programs is declining. Immigrants, who skew younger and work-age, help maintain that ratio. Without continued immigration, economists broadly agree that the fiscal pressure on these entitlement programs would be substantially more severe.

Key Sectors That Depend on Immigrant Labor

Immigration’s impact on the U.S. economy is not uniform. It is concentrated in specific sectors where demand for labor outstrips the native-born supply. In many of these industries, immigrants are not an auxiliary workforce but the primary operational engine.

The Federal Reserve Bank of San Francisco’s February 2026 research found a nearly one-for-one effect between unauthorized immigrant worker flows and employment growth, finding that local immigration slowdowns have reduced employment, especially in construction and manufacturing. In other words, for every one unauthorized immigrant who leaves a local labor market, approximately one job disappears rather than becoming available for a native-born worker.

By late 2025, the U.S. agricultural sector faced an acute crisis. With farm laborers in short supply due to enforcement policies and the chilling effect of deportation rhetoric, some farms reported crops rotting in fields due to lack of available harvest workers. The Labor Department acknowledged in a Federal Register filing in late 2025 that Trump’s immigration crackdown risked a labor shortage “exacerbated by the near total cessation of the inflow of illegal aliens.”

The Economic Cost of Reduced Immigration

What happens when immigration slows dramatically or reverses? The 2025-2026 data is beginning to provide a real-world answer, and the early signals are concerning.

Net international migration into the United States fell from 2.7 million in the year ending July 1, 2024, to 1.3 million one year later. Census Bureau estimates expect that number to fall further to just 321,000 in the year ending July 1, 2026. That is an 88 percent decline in net immigration in two years.

Brookings Institution researchers demonstrated that the decline in migration between 2024 and 2025 will reduce GDP growth by between 0.19 and 0.26 percentage points and lower consumer spending by $40 billion to $60 billion in 2025. These effects operate through multiple channels: fewer workers, fewer consumers, and reduced spending by immigrants already in the country due to heightened uncertainty and fear.

Mass Deportation Scenarios

The Peterson Institute for International Economics estimated in 2024 that deporting between 1.3 and 8.3 million undocumented immigrants would reduce U.S. real GDP by as much as 7 percent by 2028. This would represent one of the largest self-inflicted economic contractions in American peacetime history, driven by a massive supply shock in the labor market that would force businesses to cut production and raise prices.

The National Foundation of American Policy study found that Trump’s immigration policies will lower the projected average annual economic growth rate from 1.8 percent to 1.3 percent between fiscal year 2025 and fiscal year 2035. That half-percentage-point reduction, compounding over a decade, translates into trillions of dollars in foregone economic output.

Metro-Level Evidence: Where Immigration Drives Growth

Perhaps the strongest evidence for immigration’s economic benefits comes from comparing metro areas with different levels of immigrant population growth. Brookings Institution’s Metro Monitor 2026, published in April 2026 and covering data through 2024, provides a compelling geographic analysis.

Metro areas with the greatest increases in their foreign-born population share have experienced stronger economic growth, higher productivity, and better labor market outcomes for both immigrant and native-born workers. Native-born workers benefit from greater labor market opportunity in metro areas with growing immigrant populations. This finding held up across metro areas of different sizes, regions, and economic bases.

In other words, the economic benefits of immigration do not come at the expense of native workers in local communities. They come in addition to and alongside them. The presence of a large and growing immigrant community expands the economic pie rather than merely redistributing existing slices.

2025-2026 Policy Developments and Their Economic Fallout

The economic story of immigration in 2025 and 2026 cannot be separated from an aggressive wave of policy changes that has reshaped the U.S. immigration landscape more dramatically than any shift since 1965.

The economic data coming out of 2025 and early 2026 is consistent with what economists predicted: reducing immigration does not translate into more jobs or higher wages for native workers in the short run. Instead, it reduces output, raises costs for consumers in affected industries, and weakens the overall economic growth trajectory.

The Policy Debate: What Do Different Sides Argue?

Even with a strong economic consensus in favor of immigration’s net benefits, the policy debate remains intensely contested. Understanding why requires looking at the legitimate concerns that fuel restrictionist sentiment alongside the countervailing evidence.

Arguments Favoring Higher and More Structured Immigration

Economists and business groups broadly argue that America’s aging demographics, innovation deficit, and infrastructure needs require sustained immigration. They point to the $8.9 trillion CBO GDP projection, the role of immigrant entrepreneurs in Silicon Valley and beyond, and the critical role of foreign-born workers in health care, agriculture, and construction. Brookings, the American Immigration Council, and the Migration Policy Institute all emphasize that restricting immigration hurts long-term growth prospects and undermines the United States’ competitive advantage in attracting global talent.

Arguments Favoring Stricter Limits and Enforcement

Restrictionists, including some economists and many political figures, argue that the pace and composition of immigration matters enormously. They contend that rapid surges of lower-skilled workers place downward pressure on wages for the most economically vulnerable native workers, strain public services at the state and local level, and create community disruption that policymakers should take seriously. Harvard’s George Borjas argues that the distributional consequences of immigration, who gains and who loses, are not evenly shared and that the benefits flow to employers and high-income consumers while costs fall on lower-wage workers.

The debate over unauthorized immigration adds an additional dimension: concerns about rule of law, border security, and the fiscal burden on border communities are legitimate, even if the economic arguments for wholesale mass deportation do not hold up well under scrutiny.

Where Most Economists Land

Most mainstream economists support a managed immigration system that welcomes both skilled and less-skilled workers, enforces the law sensibly, provides pathways to legal status for long-established undocumented residents, and expands legal immigration pathways to meet genuine labor market needs. The debate is less about whether immigration is economically beneficial on balance and more about how to distribute those benefits more equitably and manage the process more effectively.
