Will stopping immigration cause labor shortages?

Stopping immigration would reshape the labor market - I'll pull current research on whether it triggers shortages.

Yes, according to most economic and demographic research - stopping immigration would cause labor shortages, particularly in the United States and other aging, low-birth-rate economies.

The short answer is that immigration has become the primary source of labor force growth, and without it the workforce would already be shrinking.

1. Labor force growth is now almost entirely immigration-driven

Demographers stress this is a structural issue, not cyclical:

> “The implication for the labor market is direct: without the immigration surge of 2022 to 2024, the US working-age population would have been shrinking."

2. What studies project if immigration is stopped or sharply reduced

Different models project different magnitudes, but all point to contraction:

A sudden plunge in immigration reduces the labor force available to fill jobs ... which Brookings models say will dampen employment, GDP, and consumer spending and push sustainable monthly job growth well below historical norms

The U.S. economy lost 23,000 jobs in July as roughly 200,000 immigrants lost temporary protected status, driving the first clear deportation-related labor shock

3. Which sectors would face shortages first

Tightened immigration controls are directly linked to growing labor shortages in key sectors of the U.S. economy

Labor shortages are growing in sectors that rely heavily on immigrant workers, including agriculture, construction, food service, healthcare, and transportation

Immigrant share by sector is high:

The Trump administration itself admitted in an Oct. 2 Federal Register filing: "The near total cessation of the inflow of illegal aliens combined with the lack of an available legal workforce... results in significant disruptions to production costs and (threatens) the stability of domestic food production and prices for U.S consumers."

An industry-led survey of construction firms found that 45% reported project delays attributable to ICE-related labor shortages

4. Broader economic effects

A reduction of this magnitude in the size of the labor force could have impactful economic consequences, such as renewed upward pressure on wages, which could push inflation higher... There is the potential for these dynamics to trigger supply-side inflation similar to what we experienced during the coronavirus pandemic

However, some economists note the effect on inflation is ambiguous because businesses will experience reductions in both labor supply and demand for their goods and services

Other long-term effects cited by the CBO and others:

5. Nuance: Would stopping immigration help native workers?

Research is mixed on this point:

Potential offsets often discussed are increased automation, higher wages to attract native workers, and AI. The CBO noted rising business adoption of artificial intelligence could help productivity stay afloat... By 2036, output in the U.S. economy will be 1% higher than it would have been without the help of AI, but described it as an "offsetting factor" rather than a full replacement and that AI doesn't pay taxes.

Bottom line: In an economy with record-low birth rates and retiring Baby Boomers, stopping immigration would not just cause shortages at the margins — it would reverse labor force growth entirely, create acute shortages in agriculture, construction, hospitality and health care, and lower the economy's potential growth rate. Short-term tightness might raise wages in some occupations, but most models find the net effect is fewer workers, slower GDP growth, and higher costs for consumers.
