Southern cities have secured 80% of the top 10 spots in the latest U.S. boomtown rankings released by LendingTree. Austin, Texas, earned the top ranking for the third consecutive year, driven by robust gains in population, business applications, and new housing.
Why it matters
The shift toward Southern metros is largely driven by a lower cost of living and business-friendly environments that continue to attract corporate investment. Tennessee leaders specifically leverage low-tax policies to draw companies and foster economic growth.
LendingTree evaluated 50 major metropolitan areas using metrics for population, housing, workforce, and business activity. Austin recorded 3.4% housing unit growth and an 11.3% increase in new business applications.

Macro View
The current rankings follow a established trend of rapid economic and population growth centered in Southern metropolitan areas. This shift in domestic migration mirrors historical cycles where economic hubs emerge in response to evolving tax and business environments.
Residents in high-growth boomtowns may experience tighter housing markets and rising costs of living as population density increases. Conversely, the arrival of new corporate headquarters and businesses often improves local job availability and wage growth potential.
The takeaway
The sustained dominance of Southern cities in growth rankings underscores a significant shift in corporate and residential preference toward regions with lower tax burdens. Prospective residents and businesses should account for the infrastructure pressures that typically accompany such rapid regional expansion.
