Mexican Immigrant Population Declines in the U.S.: How Could Trump’s Policies Affect the Economy?
Posted on 08/05/26 at 19:51
Beyond the political debate, the shift also has important economic implications, as millions of Mexican-born workers are employed in key industries such as construction, agriculture, and services.
- Why it matters: A smaller labor force could affect businesses, consumers, and the pace of economic growth, particularly in industries that rely heavily on immigrant workers.
The Mexican-Born Population Has Been Declining for Years
Although stricter immigration enforcement has once again become a major headline, the decline in the number of Mexican immigrants in the US did not begin during Trump’s current administration.
According to data from the Migration Policy Institute (MPI), the Mexican-born immigrant population reached its peak in 2007, with more than 11.7 million people. By 2024, that figure had fallen to approximately 11.1 million.
The decline reflects several long-term factors, including fewer new migrants arriving from Mexico, the aging of the Mexican-born population, and demographic changes within Mexico itself.
However, tighter immigration restrictions and increased border enforcement could contribute to the continuation of this trend.
Key US Industries Could Face Greater Labor Pressure
Mexican immigrants in the US make up a significant share of the American workforce. According to the Migration Policy Institute, they are heavily concentrated in industries such as:
- Construction
- Agriculture
- Restaurants and hotels
- Maintenance services
- Manufacturing
If employers have greater difficulty hiring workers, some businesses could delay projects, reduce operations, or face higher labor costs to fill open positions.
This does not necessarily mean those jobs will disappear, but certain industries could experience labor shortages, particularly in regions that have historically relied on immigrant workers.
The Economic Impact Extends Beyond the Labor Market
The effects go beyond employment. Immigrants also purchase goods and services, pay rent, and contribute to local economies.
An analysis by the Brookings Institution indicates that lower immigration levels may reduce consumer spending and slow economic growth in some communities.
In addition, if businesses face higher labor costs because of worker shortages, part of those additional expenses could eventually be passed on to consumers.
Meanwhile, the Pew Research Center has noted that the recent decline in the immigrant population is the result of multiple factors and cannot be attributed solely to deportations or any single public policy.
Trump’s Immigration Policies Could Accelerate the Trend
Measures introduced by the Trump administration—including stronger border enforcement and expanded immigration operations—could further reduce the arrival of new immigrants while encouraging some workers to leave the country.
Even so, experts agree that the decline in the Mexican immigrants in the U.S. population began long before the current administration and reflects demographic and economic changes that have developed over more than a decade.

What Comes Next
If the number of Mexican workers entering the United States continues to decline, some sectors of the US economy could face greater challenges filling open positions.
The long-term impact will depend on how immigration policy evolves, labor market demand, and businesses’ ability to recruit and retain new workers.
