While the Midwest’s economic revival is driven by a return to its industrial roots, a parallel evolution is unfolding in the nation’s high-growth exurbs.
An expanding digital infrastructure of high-tech corridors at the outermost fringes of the residential areas of metropolitan cores is stretching from the Eastern Seaboard to the Sun Belt.
“The fastest-growing counties in the country—specifically those with over 10,000 residents—will be on the fringes of major metro areas,” says Kenneth D. Simonson, chief economist at the Associated General Contractors of America. “It’s not going to be in Travis County where Austin is, as it is already built out, or even Williamson County, which adjoins it. It will be the second county out from there.”
This metamorphosis is particularly visible in Northern Virginia, where the historic sprawl beyond Washington, D.C., has turned into tech zones like Loudoun County’s Data Center Alley, which hosts approximately 200 high-security data centers, with another 117 of these facilities in development as of early 2026. This density is so significant that roughly 70% of the world’s daily email and internet traffic passes through the county.
For the local community, the industry acts as a massive fiscal engine, generating nearly half of the county’s property tax revenues and providing a 26-to-1 return on investment for public services. The localized economic boom is underpinned by a multibillion-dollar reinvestment in health and education. While some neighboring jurisdictions have adjusted plans due to shifting demographics, Loudoun County is moving forward with high-tech, net-zero school campuses, such as the $202 million High School 14 in the Dulles North district, which is slated for a 2028 opening.
Simultaneously, regional leaders like Inova and UVA Health are spending billions on expansions, including a $10 million overhaul of the Prince William Medical Center in Manassas and the opening of a new 9,000-square-foot imaging center in Gainesville in early 2026. These medical hubs are designed to offer everything from pediatric cardiology to neurological research, ensuring Virginia exurbs are no longer dependent on the urban core for high-level care.
A similar phenomenon is evident in the northern exurbs of Atlanta, where Forsyth, Cherokee, and Dawson counties now power the state’s growth. Thanks to a strategic industrial diversification effort to attract high-tech, manufacturing, biotech, and research and development firms, Dawson County is the fastest-growing county in the state and ranks second in the nation for population percentage growth, according to 2026 U.S. Census Bureau data. Massive civic investments, like a $330 million high-tech high school campus in Cherokee and a planned mixed-use “city of the future” in Forsyth, are pulling professional talent away from Atlanta.
Even in small-town Georgia, high-paying jobs are available in the state’s Green Corridor tech hubs. “I live halfway between Atlanta and Chattanooga, Tennessee, in a small community in northwest Georgia called Resaca,” says Jim Dunn, U.S. head of Construction at Marsh. “Within driving proximity is a solar manufacturing plant in Dalton, and a Hyundai battery plants about 30 miles south. Multifamily housing and hotels are springing up, but we’ve retained our quiet, small-town atmosphere and low cost of living.”
In Central Texas, explosive population growth is occurring in the immediate, built-out exurbs of Austin. “The 195 miles or so between Austin and San Antonio are now one long, giant continuous suburb, where as much [economic] activity happens in between the cities as in them,” says Kirk Chamberlain, executive vice president and National Construction Practice leader at Hub International.
Kaufman County, on the eastern edge of the Dallas-Fort Worth metroplex, is heralded as the next frontier of North Texas. Kaufman currently ranks as the fastest-growing county in the entire state, recording a near-unprecedented 50% population increase since 2020 as it attracts young families priced out of the inner suburbs.
“Everyone points to the bigger southern markets like Atlanta or Dallas when discussing growth, but those have actually rolled over; Atlanta and Dallas are no longer leading the way. Instead, it is Gulfport, Huntsville, and Fayetteville,” says Brian Stobie, vice president and head of product for the Macro Trends Group at management consultant Bain. “These are the markets that are now showing major gains. It’s no longer dirt cheap to live in Atlanta or Dallas; they are no longer bargain prices or screaming deals. However, this next generation of cities still offers those bargains.”
The primary drivers of this geographic shift are high-income professionals under 35 who are gravitating toward markets that have reached a critical threshold for lifestyle and amenities, Stobie maintains. “These cohorts are the precursors of the next Austins or Greenvilles; their migration signals that the choice is no longer just about taxes, but about a relative quality of life that the Heartland provides—much less traffic, more greenspace, and better balance of life and work to raise one’s kids.
