(UNITED STATES) Migration is often discussed in emotional and political terms, but the hard economic story is clear: countries that receive migrants tend to grow richer, not poorer. A wide range of research shows that when people move, host countries gain higher GDP, stronger public finances, and a more flexible labor market. Economists often call this gain for local citizens the “immigration surplus” – the extra income that goes to people already living in the country because migrants have joined the economy.
How Migration Raises GDP
When migrants enter a country and start working, the size of the workforce grows. With more people producing goods and services, total output rises and GDP increases.
Studies cited by Tufts University show that a 1% increase in migration inflow raises employment among native-born workers by 0.2%. That indicates migration does not simply “take jobs”; it also helps create work for people already in the country.
The immigration surplus measures the gain captured by native-born residents. Research finds that immigration typically adds 0.2–0.4% to native GDP each year. In the United States 🇺🇸, this surplus is estimated at $36–72 billion per year. This extra income reflects higher productivity, better matching of skills to jobs, and a larger overall economy — not migrants losing out.
Migrants fill roles across the economy — from high-tech to agriculture. They help hospitals stay staffed, farms harvest crops, and technology firms grow. By keeping key sectors running, they protect and increase income for local workers and business owners, which feeds back into higher GDP.

Labor Shortages, Productivity, and Occupational Shifts
Many advanced economies face aging populations and shrinking workforces. Fewer young workers mean gaps in sectors such as healthcare, technology, and agriculture. Migration helps fill these gaps, ensuring factories, farms, and clinics continue operating.
When migrants step into roles that would otherwise remain vacant, several things happen:
- Output rises because more work is completed.
- Productivity improves as firms better match tasks to skills.
- Native workers move into better-matched jobs, often with higher pay or more responsibility.
Over time, this occupational reshuffling raises total production and supports the immigration surplus. Rather than a fixed number of jobs, the labor market adjusts: migrants enable firms to expand, launch new projects, and serve more customers, which then supports more jobs for natives.
According to analysis by VisaVerge.com, this pattern — migrants filling needed roles and supporting higher productivity — recurs in host countries, especially where there are clear labor shortages and aging populations.
Consumer Demand, Local Businesses, and Job Creation
Migrants are not only workers; they are also consumers. They rent or buy homes, purchase food, use transport, and pay for services from haircuts to phone plans. This additional demand supports local businesses and encourages new ones to open.
Typical local effects when new families arrive:
- Grocery stores sell more and hire extra staff.
- Landlords invest in repairs or new housing.
- Bus and rail systems gain riders, helping keep routes open.
- Small shops — cafes, bakeries, clothing stores — see higher sales.
This chain reaction boosts jobs for both native-born residents and migrants. In economic terms, migration raises both the supply of labor (more workers) and the demand for goods and services (more customers), which tends to keep the overall impact on local employment positive, especially over the long run.
Innovation, Entrepreneurship, and Long-Term Growth
Another important channel for higher GDP is innovation and entrepreneurship. Migrants are often more willing to take risks, start businesses, and try new ideas in their host countries. They bring different training, languages, and problem-solving approaches, helping firms reach new markets or create new products.
Research shows migrants are more likely than natives to:
- Start small and medium-sized companies.
- Open restaurants, shops, and service firms serving both migrant and native communities.
- Launch tech start-ups or research projects, particularly when arriving with advanced skills.
These businesses hire staff, pay taxes, and invest in future growth. Over time they foster a more dynamic economy with stronger job creation. This innovative energy helps explain why high-income countries benefit from migration, particularly in sectors that depend on new ideas.
Fiscal Contributions and Public Budgets
Public debate often asks whether migrants cost more in services than they pay in taxes. Evidence from many OECD countries points the same way: migrants are usually net contributors to public finances, especially when well integrated into the labor market.
Migrants pay:
- Income taxes on wages.
- Sales taxes on purchases.
- Social security contributions that fund pensions and health systems.
In South Africa, for example, studies show immigrants make a positive net fiscal contribution, paying more in taxes than they receive in public benefits. That means they help support schools, hospitals, and pensions for everyone.

Jobs, Wages, and the “Immigration Surplus” Debate
A sensitive question is how migration affects native wages. Many fear new workers will push down pay or reduce job opportunities. However, most empirical studies show the long-term effects on native employment and wages are positive or neutral for the majority of workers.
Research findings include:
- Some native workers directly competing with migrants in the same low-skill niche may see temporary wage drops.
- Over time, these workers often shift into different roles or tasks, including supervisory positions.
- The wider economy benefits from better skill-job matching, higher total production, and new business growth.
These aggregate gains create the immigration surplus — the share of extra GDP that goes to native-born residents. While the adjustment period can be painful for some, the broader labor market picture is one of modest short-term strain followed by long-term benefit.
Many economists therefore recommend active labor policies and training to help native workers transition into better positions while preserving the economic upside of migration.
Key takeaway: Migration can cause short-term disruption for a subset of workers, but with proper policy and training, the long-term effects for native employment, wages, and public finances are generally positive.
Demographic Pressures and Social Stability
Many high-income countries face aging populations and falling birth rates. This trend threatens pension systems, health budgets, and the supply of workers needed to care for older people. Migration can slow or counter these pressures by adding younger workers and families.
Effects include:
- A larger working-age population that supports retirees through taxes.
- More care workers in healthcare and eldercare sectors.
- A more balanced age structure, supporting long-term economic sustainability.
Beyond economics, migrants contribute social and cultural benefits. They bring languages, foods, and perspectives that can open trade links and investment flows with their countries of origin. These global connections support business relationships and export growth, further boosting GDP.
Global Welfare Gains and Policy Choices
The World Bank estimates that increased cross-border labor mobility could produce global welfare gains several times larger than those from full trade liberalization. High-income countries would gain extra labor, skills, innovation, and entrepreneurship, while migrants would earn higher incomes and improved life chances.
However, gains are not automatic. They depend on effective integration policies, such as:
- Fair access to the labor market.
- Language training and recognition of foreign qualifications.
- Housing and education policies that prevent overcrowding and exclusion.
Short-term strains may appear in public services and infrastructure, especially where large inflows arrive quickly. If local schools, clinics, or transport systems are already weak, sudden migration can expose those weaknesses. These are problems of planning and investment rather than evidence that migration is inherently harmful.
Countries that invest in smart integration and adjust public services to new populations tend to realize long-term benefits: higher GDP, stronger tax bases, and a lasting immigration surplus for their citizens.
Research shows migration raises GDP, employment and public revenues. A 1% inflow boosts native employment by 0.2%. The immigration surplus typically adds 0.2–0.4% to native GDP annually, estimated at $36–72 billion in the US. Migrants fill critical roles, increase consumer demand, and foster entrepreneurship. Benefits depend on integration policies such as language training and credential recognition to limit short-term strains on services and maximize long-term gains.
