Will stopping immigration cause labor shortages?

Stopping immigration raises big labor questions — I'll review the evidence on what would happen to worker supply.

Yes, according to most economic modeling stopping immigration entirely would worsen — and in many sectors cause — labor shortages, especially over the medium to long term.

It would not affect all jobs equally. The impact is strongest due to demographics and sectoral dependence:

1. The U.S. labor force is already shrinking without immigration

The future of America's economic strength depends on immigration. As the US birth rate declines and the median age goes up, fewer US-born workers will enter the labor force. It is a scenario that, left unaddressed, would spell a shrinking economy and strained public finances. Immigrants lean younger and are more likely to be in their prime working years.

Economists say changing demographics like aging and retiring workers are a factor behind the shortages, as well as border controls and immigration limits.

Historically immigration has been the main source of labor force growth:

Without it, the CBO and private forecasts project an outright decline in the working-age population.

2. Modeled impacts of stopping or sharply reducing immigration

3. Shortages would be concentrated in immigrant-reliant sectors

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

Estimates of current reliance:

Other reports put foreign-born workers at 18.4%, nearly one-fifth of the American workforce prior to mid-2025.

In those industries, employers report delayed projects, harvest delays, and hospital staffing crises. The U.S. labor market faces a growing crisis as restrictive immigration policies exacerbate shortages in sectors reliant on immigrant workers—construction, agriculture, and healthcare.

4. Why native-born workers would not fully fill the gap quickly

Standard labor economics notes two offsetting effects:

> Though immigration increases the supply of labor, it also increases the demand for labor, which offsets the downward pressure on the wages and employment of nativeborn workers caused by the increase in supply.

Differences in language skills significantly limit competition between immigrants and nativeborn workers for jobs, and a large part of the academic literature reports that the effect on average native wages, over a decade or more, is small.

In other words, stopping immigration would not automatically create a one-for-one job opening for native workers, because many of those jobs are physically demanding, seasonal, lower-paid, or geographically concentrated where native workers are not available, and because immigrant spending also creates jobs.

5. Counter-arguments and mitigations

Not all economists agree the shortage would be economy-wide and permanent:

The U.S. economy has become structurally dependent on immigrant labor to fill critical gaps, especially given domestic demographic trends.

Bottom line: Completely stopping immigration would not cause an immediate shortage in every occupation, but almost all mainstream demographic and economic forecasts conclude it would reduce total labor supply, deepen existing shortages in agriculture, construction, hospitality, and healthcare, slow GDP growth, and make it harder to replace retiring Baby Boomers — because immigration is projected to provide essentially all of U.S. population and labor-force growth in the coming decade.
