Immigration Slowdown Reshapes the US Sun Belt

The economic model that powered the US Sun Belt through rapid population growth, construction and consumer demand is facing a new constraint. International migration has fallen sharply, while domestic inflows into some Texas and Florida markets have also slowed. For housing, that means fewer new renters and buyers just as homes and apartments planned during the post-pandemic building boom are reaching the market. Bloomberg links the demographic shift to a broader slowdown across parts of the South, although immigration is only one element of the adjustment.

US population growth has halved

The US population increased by 1.8 million, or 0.5%, between July 1, 2024 and July 1, 2025. A year earlier, the increase was 3.2 million, or 1%.

The main reason for the slowdown was a decline in net international migration to 1.3 million from 2.7 million. If recent trends persist, the Census Bureau estimates the figure could fall to about 321,000 in the 12 months through July 2026. Population growth in the South slowed at the same time to 0.9% from 1.4%.

Texas still expanded rapidly, adding 1.2%, while North Carolina grew 1.3%. The data therefore do not support the idea that Sun Belt population growth has stopped. What has changed is its pace and composition.

Florida provides one of the clearest examples. Net domestic migration fell to 22,517 people in 2025 from 183,646 in 2023 and 310,892 in 2022. International migration also slowed, even though Florida and Texas continued to post some of the country's largest absolute gains from overseas arrivals.

Homes planned during the boom are reaching the market

The timing creates a problem for developers. A large share of the houses and apartment buildings opening now were planned when population growth in southern metropolitan areas was considerably stronger.

Builders sharply expanded supply across Texas, Florida, Arizona and other southern states after the pandemic. Those units are now being delivered as migration slows and mortgage borrowing remains expensive.

Sales of new single-family homes ran at a seasonally adjusted annual rate of 607,000 in July 2026, down 10.5% from June. There were an estimated 488,000 new homes for sale, equivalent to 9.6 months of supply at the current sales pace. The median sale price was $393,800.

Construction has weakened as well. Housing starts fell 12.4% from June and 13.5% from a year earlier in July to an annualized 1.239 million. Single-family starts were running at 808,000.

That correction is reducing builders' demand for additional land and contractors and should gradually limit future supply.

Austin shows how far the market has shifted

Austin remains one of the clearest examples of the post-pandemic housing adjustment. The median listing price was about $450,000 in August, down 9.8% from a year earlier, and homes spent a median 73 days on the market.

The supply buildup has stopped accelerating, however. Active listings were only 0.3% higher than a year earlier, suggesting that the market is moving from rapid inventory accumulation toward a slower correction, according to Realtor.com.

Closed-sale data tell a more moderate story. Over the three months through August, Austin's median sale price was roughly 1% lower than a year earlier while transaction volumes increased. The market remains far cooler than during the pandemic boom, but the latest figures do not point to an uninterrupted collapse.

Household formation is becoming the key risk

For housing, the number of households matters more than population alone. A person who arrives in a city does not necessarily need a separate home immediately, while a newly formed household generally does.

Total US household growth was about 1.1 million in 2025. The immigration slowdown had only a limited effect that year because many immigrants establish independent households one or two years after arriving.

Harvard's Joint Center for Housing Studies expects the impact to become substantially larger in 2026 and 2027. Its estimates suggest that the immigration drop could reduce annual household formation among recent immigrants by about 420,000 in both years. If net immigration remains around 300,000, household growth generated by recent immigrants could fall to just 143,000 in 2027.

For developers, that means projects underwritten several years ago may open into a very different demand environment.

Rental vacancy is elevated but not surging nationally

The national rental vacancy rate was 7.3% in the second quarter of 2026, compared with 7% a year earlier. The Census Bureau says the difference was not statistically significant, and the rate was virtually unchanged from the first quarter.

Individual Sun Belt markets face more pressure because of the scale of recent apartment construction.

A survey of multifamily operators reported by Multifamily Dive found that 67% of respondents in Florida viewed immigration-related effects on leasing and occupancy as somewhat negative. In Texas, 26% reported a somewhat negative impact and another 21% a significant one. Across the Southwest, 39% reported some degree of negative effect.

Those findings should not be treated as a measure of the entire rental market. Occupancy also reflects new supply, rents, household finances and local employment conditions.

Florida and Texas rely heavily on foreign-born builders

Lower immigration affects real estate from both directions. It reduces potential housing demand while also restricting labor supply in construction.

Foreign-born workers represented 26.3% of the entire US construction workforce in 2024 and about one-third of workers in construction trades.

Their share reached 40.6% in Florida, 39% in Texas and 38.6% in Nevada. Foreign-born workers account for 57% of drywall and ceiling-tile installers, 56% of plasterers and stucco masons, 53% of roofers, 53% of painters and 51% of flooring and tile installers, according to the National Association of Home Builders.

That leaves the Sun Belt unusually exposed: it has been building more housing while relying heavily on workers born outside the country.

Enforcement can affect other workers as well

Employment effects can extend beyond immigrants directly affected by enforcement.

Economists Elizabeth Cox and Chloe East studied areas that experienced particularly large increases in Immigration and Customs Enforcement arrests. Employment declined among likely undocumented immigrants who remained in the US, and the researchers also found a decline in the number of US-born men at work.

They attribute the result to a combination of complementarities between workers and weaker local economic activity. The research is an NBER working paper and has not yet gone through the standard peer-reviewed journal publication process.

The mechanism is particularly relevant to construction. If part of a crew is unavailable, work can slow for supervisors, drivers, engineers and suppliers regardless of their immigration status.

Construction is still adding jobs

There is no evidence of a nationwide collapse in construction employment. The US added 162,000 payroll jobs in August 2026, including 22,000 in construction. Industry employment reached about 8.36 million.

At the same time, housing starts and residential construction spending are falling. Private residential construction spending declined 1.3% in July from June, while total construction spending was 3.8% below its level a year earlier.

That helps explain why reduced labor supply has not created an equally severe shortage everywhere. Builders need fewer workers for new projects than they did at the peak of the construction cycle.

Immigration increased both employment and housing demand

Research from the Federal Reserve Bank of Dallas shows the other side of the current adjustment. Economists examined the surge in unauthorized immigration between early 2021 and early 2024 and found that immigrant-worker inflows increased local employment approximately one-for-one, without statistically significant declines in local wages.

The same inflows pushed up local home prices and rents, while the researchers found little evidence that housing supply expanded in response. In the short term, migration therefore acted as a demand shock in the housing market.

The reversal has the opposite implications. Lower migration reduces housing demand but also slows labor-force and consumer-spending growth.

The effects extend beyond real estate

Brookings estimates that US net migration in 2026 could range from negative 925,000 to positive 185,000. The unusually wide interval reflects the uncertainty surrounding current migration data, so no single point estimate should be treated as precise.

Researchers estimate that reduced migration could lower consumer spending by a further $10 billion to $40 billion in 2026 after a $40 billion to $60 billion decline in 2025. The combined effects of a smaller labor supply and weaker spending could reduce real US GDP growth by about 0.1 to 0.3 percentage point this year.

The impact may be more visible in fast-growing Sun Belt cities because housing, retail, services and construction had been planned around continuing population gains.

Domestic migration is slowing too

The international immigration slowdown has coincided with weaker flows of Americans into several southern metropolitan areas.

Tampa recorded a net domestic inflow of a little more than 10,000 people in 2024, down from roughly 35,000 a year earlier. Dallas fell from about 35,000 to around 13,000, while Atlanta posted a small net outflow, according to Redfin.

Over a longer period, domestic migration remains a major force. The Dallas metropolitan area gained about 270,000 residents through net domestic migration between 2020 and 2025, the largest gain among major US metros. Much of that growth occurred in outer suburbs.

This is one reason Sun Belt markets are diverging. Cities that continue to attract domestic migrants may absorb excess housing more quickly than places where both domestic and international inflows have weakened.

Immigration was part of the Sun Belt growth model

Between 2014 and 2024, metropolitan areas with larger increases in the foreign-born share of their working-age populations generally recorded stronger economic and employment growth.

The group included Raleigh and Charlotte in North Carolina and Cape Coral in Florida. Employment rates for both US-born and foreign-born workers were nearly 3 percentage points higher in metros with the largest increases in their foreign-born workforce share than in those with the smallest increases, according to Brookings' Metro Monitor 2026.

The relationship does not prove that immigration alone caused stronger growth. Successful metropolitan economies also attract workers, companies and investment. It does show that foreign-born labor was an important part of the expansion experienced by many fast-growing regions.

The Sun Belt can no longer be treated as one market

Lower migration does not amount to a broad economic crisis across the South. South Carolina, North Carolina, Texas, Arizona and several other states are still adding residents, while companies continue to invest in data centers, manufacturing, energy, logistics and infrastructure.

What has changed is the reliability of the old assumption that rapid population growth would continue almost automatically.

Housing markets with large construction pipelines and weakening migration face the greatest risk of prolonged softness. Markets with durable job growth, continuing domestic inflows and rapidly shrinking development pipelines are in a stronger position.

As International Investment experts report, lower immigration is amplifying a housing adjustment that had already begun because of high mortgage rates and heavy construction. The main risk for investors lies in projects still underwritten on the demographic assumptions of 2021–2024. Lower migration reduces demand while also constraining labor supply, so the outcome will differ sharply by city. Markets with durable employment and modest construction pipelines may absorb the change relatively well, while places combining heavy development with weaker migration are likely to take longer to rebalance.

FAQ

Why does immigration matter so much to the Sun Belt?

Southern states have received substantial population gains from both domestic relocation and international migration. New residents generate demand for housing, goods and services while also expanding the labor force.

Are Texas and Florida now losing population?

No. Both states are still growing. What has changed is the pace of that growth and the size of migration inflows compared with the peak years.

Will lower immigration push home prices down?

It removes one source of demand and can weigh on prices and rents in markets with abundant new housing. Mortgage rates, employment, domestic migration and supply remain equally important.

Why hasn't the construction labor shortage become much worse?

The supply of workers has tightened, but housing construction has also slowed. Lower demand for contractors is offsetting part of the reduction in labor supply.

Which states depend most heavily on foreign-born construction workers?

Among the largest markets, Florida and Texas stand out. Foreign-born workers account for roughly 41% and 39% of their construction workforces respectively.

What does the immigration slowdown mean for rents?

In cities with large apartment pipelines, slower household formation can prolong concessions and weak rent growth. The effect will be smaller in markets where construction has remained limited.

Is the Sun Belt boom over?

There is no single answer for the entire region. Some metropolitan areas continue to grow rapidly, while others are correcting after several years of heavy construction and migration. Differences between individual markets now matter more than the Sun Belt label itself.
