America's fastest-growing cities aren't simply adding residents. In the places leading the latest boom, new homes, workers, and economic output are expanding together—reshaping communities in the process.
That kind of growth can transform a city in just a few years. Employers move in, housing developments spread across former farmland, and local tax bases swell. Roads, schools, and infrastructure have to keep pace. The upside is obvious for businesses, job seekers, and people looking for more room to live. The downside can be just as visible: higher rents, heavier traffic, and communities changing faster than longtime residents ever expected.
Between 2019 and 2024, a handful of U.S. cities dramatically outpaced the national rate of growth in housing, employment, and economic output. Central Texas dominated the rankings, while the Mountain West also produced a standout. Meanwhile, much of the Northeast and Rust Belt saw comparatively modest growth.
The most revealing measure isn't any single statistic. A city can build homes without creating enough jobs to support them, or attract employers without adding enough housing for incoming workers. The places that managed to expand their housing stock, workforce, and economic output simultaneously are the real standouts.
SmartAsset analyzed a broad group of mid-size and larger U.S. cities, starting with places that had populations above 65,000. It then evaluated how much each city's economy, housing stock, and workforce changed over five years. The 75 highest-scoring cities made the final ranking.
Florida and Texas accounted for nearly half of those 75 cities, while the Northeast produced only one. Five cities rose to the top.
1. Georgetown, Texas
Georgetown didn't merely make SmartAsset's list—it took the No. 1 spot by posting exceptional growth across all three measures.
Between 2019 and 2024, the city's housing stock grew 34%, while its labor force expanded by exactly the same percentage. That kind of balance is unusual: Georgetown added homes and workers at almost identical rates rather than allowing one side of the equation to dramatically outpace the other.
The broader economy was expanding just as quickly. Williamson County, where Georgetown is located, recorded compound annual real GDP growth of 7.7% during the period—the highest rate among the counties represented by cities in the top five.
Georgetown's location helps explain the momentum. About 30 miles north of Austin, the city has benefited from the broader Central Texas boom in technology and manufacturing. Pegatron, a Fortune 500 technology and artificial intelligence manufacturer, recently acquired a 168,000-square-foot facility in Georgetown, adding to the city's growing industrial base.
The transformation is changing Georgetown's identity, too. Once best known as a quiet retirement destination, the city is now attracting a younger population of workers and families while retaining its established retiree community. Its historic town square—long celebrated locally as one of Texas' most beautiful—remains a defining feature even as new development accelerates around it.
Georgetown's population topped 100,000 in 2025, nearly 50% above its 2020 level. Much of that increase came during 2022 and 2023. Sun City, the large age-restricted community within Georgetown, continues to draw retirees, while commuters and manufacturing workers are adding a different demographic to the city's economic mix.
That combination gives Georgetown a broader base than many rapidly growing Texas suburbs that rely heavily on a single industry.
Texas placed 18 cities among SmartAsset's 75 boomtowns, second only to Florida's 19. Georgetown edged out nearby New Braunfels to claim the state's highest position.
2. New Braunfels, Texas
New Braunfels came in just behind Georgetown, and in one important category it grew even faster.
The city's housing stock surged 40% between 2019 and 2024—the largest increase among the five cities at the top of the ranking. Its labor force grew 32%, while Comal County recorded compound annual real GDP growth of 6.8%.
Geography has been a major advantage. New Braunfels sits between Austin and San Antonio at the confluence of the Comal and Guadalupe rivers, putting it directly in the path of one of Texas' most powerful growth corridors.
It's also a major tourism destination. Schlitterbahn Waterpark and Resort attracts more than a million visitors annually, while tourism as a whole has an estimated $1.3 billion annual impact on the local economy and supports more than 16,000 jobs.
Importantly, that tourism economy has expanded alongside the city's residential and employment base rather than replacing it. Hospitality employment grew 13% between 2022 and 2024 as the city's population and housing stock continued to climb.
Much of the population growth is coming from elsewhere in the region. Nearly half of Comal County's growth comes from people relocating from neighboring Bexar, Guadalupe, Hays, Travis, and Williamson counties—the same Austin-to-San Antonio corridor driving Georgetown's expansion.
New Braunfels is also becoming more highly educated. The share of adults with at least a bachelor's degree increased by more than 13 percentage points over five years, reaching 42%.
So why did New Braunfels finish behind Georgetown despite building more housing?
The difference came down to the other measures. Georgetown recorded slightly stronger labor-force and GDP growth, giving it the edge in SmartAsset's overall scoring.
New Braunfels has been gaining recognition beyond economic rankings as well, including a Destination of the Year award from the Texas Travel Awards and a spot on Forbes Advisor's list of top travel destinations.
3. Lehi, Utah
Lehi is the lone city outside Texas to break into the top five—and its workforce growth is the number that immediately stands out.
Between 2019 and 2024, Lehi added 39% more housing units, while its labor force jumped an extraordinary 67%. That's the largest labor-force increase among the five cities ranked here by a wide margin.
The growth translated into compound annual real GDP growth of 5.6% for Utah County during the same period. That was slower than the rates recorded in Georgetown and New Braunfels, but Lehi's workforce expansion was in a league of its own.
The city's location is central to the story. Lehi sits at the northern end of Utah County within the technology corridor known as Silicon Slopes, which stretches along Interstate 15 from Provo through Lehi and toward Salt Lake City.
Major technology companies have established a substantial presence there. Adobe has operated a campus in Lehi for years and employs more than 3,000 people. Microsoft and Texas Instruments also have major facilities in the city.
Texas Instruments alone has committed $11.5 billion across two Lehi facilities, with at least 800 new jobs promised at its newer plant. Suppliers are already scouting nearby locations, potentially adding another layer of industrial growth.
But Lehi's success comes with a familiar problem: growth can make a place harder to afford.
The city's population has nearly doubled since 2010, putting pressure on roads and housing. Home prices have risen sharply as technology-sector salaries have pushed housing costs beyond the reach of some workers outside the industry, including teachers, healthcare employees, and other service workers.
Some employers have responded with housing stipends and down-payment assistance to help retain employees who are increasingly priced out of the communities where they work.
That tension distinguishes Lehi from the more economically diversified Texas cities above it. Utah's technology sector now accounts for close to 10% of the state's overall economic output, making Lehi's growth unusually dependent on one industry.
4. Leander, Texas
Leander is the third Central Texas city in the top five, and its numbers point to a city rapidly evolving beyond its old role as an Austin bedroom community.
Between 2019 and 2024, Leander's housing stock expanded 48%—the largest housing increase among all five cities. Its labor force grew 25%, while the local economy, measured through compound annual real GDP growth in the surrounding county, expanded 6.1%.
The city is about 20 miles north of Austin, close enough to benefit from the region's economic expansion while offering more space and comparatively lower housing costs.
But Leander is increasingly building an economic identity of its own.
The 50-acre Leander Tech Park, developed by St. John Properties, is bringing the city its first Class A office building along with 270,000 square feet of flex and retail space. Once complete, the project is expected to generate roughly 850 jobs.
A separate 115-acre business park from Titan Development could add as much as 1.3 million square feet of industrial space, addressing a longstanding shortage of Class A industrial facilities. Meanwhile, a $48 million retail and dining project on Crystal Falls Parkway is adding another 155,000 square feet of commercial space.
The city's most ambitious development may be Northline, a 116-acre mixed-use district near the MetroRail station and an Austin Community College campus. The project is designed to create something Leander has historically lacked: a genuine downtown-style center where residents can reach retail, restaurants, and offices on foot.
Leander's population passed 80,000 in 2023 and is projected to continue rising sharply in the years ahead. Even with that growth, its cost of living remains about 5% below the national average.
Transit is another advantage. Rail access to Austin, combined with housing that remains less expensive than comparable properties closer to downtown, continues to attract residents.
By February 2026, Leander's median home sale price had reached $451,210, with roughly six months of housing supply available—a level local real estate agents consider relatively balanced between buyers and sellers.
5. Lewisville, Texas
Rounding out the top five is Lewisville, the highest-ranked city in the Dallas-Fort Worth region.
Its growth was less explosive than that of the cities above it. Between 2019 and 2024, Lewisville added 24% to its housing stock and expanded its labor force by 23%. But Denton County still recorded compound annual real GDP growth of 6.7%, placing the city firmly among the country's fastest-growing economic centers.
Lewisville's advantage is less about a sudden transformation and more about a strong foundation.
Located near the center of the Dallas-Fort Worth Metroplex, the city has spent decades building an industrial economy around its strategic location. Its light-industrial zoning dates to the 1970s, when proximity to Dallas-Fort Worth International Airport encouraged planners to reserve land for warehouses and manufacturing.
That industrial base remains remarkably strong.
Industrial occupancy in Lewisville stood at 97% in 2026, supporting nearly 49,000 jobs within the city. Healthcare, logistics, and professional services have expanded alongside the traditional industrial sector, giving Lewisville a broader economic mix.
More than one million square feet of new office and industrial construction is currently in the development pipeline.
The city's appeal is also attracting established businesses. McAdams Engineering, a design and engineering firm with three decades of history in Lewisville, recently moved its office to a new mixed-use development at The Realm at Castle Hills, citing the project as a better fit for the company's growth.
Lewisville isn't the only North Texas city benefiting from the region's expansion. McKinney ranked eighth nationally and Frisco 10th on the same SmartAsset list, highlighting how growth across the Dallas-Fort Worth area is concentrated across a network of rapidly expanding suburbs.
For Lewisville, the No. 5 ranking represents continuity as much as acceleration. The city ranked ninth on SmartAsset's boomtown list in 2022. Its rise to fifth suggests that the current momentum is the result of years of economic development rather than a short-lived spike.
What the rankings reveal
The biggest takeaway from SmartAsset's ranking isn't simply that Texas dominates the list. It's that the fastest-growing cities are succeeding when several forms of growth reinforce one another.
Georgetown and New Braunfels are benefiting from the enormous economic pull of the Austin-San Antonio corridor. Lehi is riding Utah's technology boom. Leander is transforming from a commuter suburb into a more self-contained economic center. Lewisville is leveraging decades of industrial investment while adding newer sectors to its economy.
But rapid growth is not without consequences. More jobs attract more residents, which increases demand for housing. More housing brings pressure on roads and infrastructure. Higher wages in fast-growing industries can push up property prices, potentially pricing out the workers who support the local economy.
For businesses and workers, however, these cities remain among the clearest examples of where America's economic expansion is taking shape right now.
The challenge for each will be turning that momentum into growth that remains sustainable long after the boom has passed.
