Will stopping immigration cause labor shortages?

Will halting immigration tighten labor markets? I'll pull the latest data on workforce gaps.

Yes, according to most economic research, stopping immigration would cause - and is already causing - labor shortages, particularly in the United States.

Demographics: Without immigration the workforce shrinks

> "without the immigration surge of 2022 to 2024, the US working-age population would have been shrinking. ... The prime-age labor force grew in large part because of immigration"

Research from the Federal Reserve Bank of San Francisco found:

> "without new immigration, the U.S. working-age population ages 16 to 64 would have started to decline in 2012"

And:

> "The Federal Reserve Bank of San Francisco found that without immigration, the U.S. working-age population would have started shrinking in 2012, not 2025"

Current trends show the problem accelerating:

> "net migration will be close to half a million people in 2025, down from 2.2 million in 2024"

Estimates suggest that even that level is "below the level of net migration necessary to sustain positive growth in the working-age population".

Pew Research projected that "Without them, the number of working-age Americans would drop to 166 million by 2035".

The Indeed Hiring Lab summarized the demographic reality:

> "The United States is aging, and immigrants, on average, are more likely to be of prime working age than native-born Americans"

> "Put simply, immigration will soon become the primary mechanism keeping the population and the labor force growing. Without it, the U.S. will not just be facing a tighter labor market, but a shrinking one."

San Francisco Fed projections show that without immigration, "prime-age labor force growth will likely continue to slow and turn negative around 2042".

Sectors most affected

Immigrants are disproportionately concentrated in sectors with chronic shortages:

> "Foreign-born workers accounted for about a fifth of the US labor market in 2024" and "were more likely than native-born workers to be employed in service occupations, natural resources, construction and maintenance, and production, transportation, and logistics. These are sectors with chronic labor shortages and limited domestic supply pipelines"

Specific concentrations:

Measured economic consequences

Studies of the recent slowdown already show effects:

Nuance and counter-arguments

Not all effects are purely supply-side. Economists note that reduced immigration also reduces demand for goods and services, so they "expect negative immigration to have little impact on prices and inflation because businesses will experience reductions in both labor supply and demand".

In the very long term, some analysts argue "telehealth and AI diagnostics may offset labor shortages", and higher wages or automation could attract more native-born workers or increase productivity. However, most labor economists conclude that due to aging (all baby boomers will be over 65 by end of decade) and low native birth rates, there is no domestic pipeline to replace immigrant workers within 5-10 years without significant immigration.
