Southwest Ohio’s stretch of the Miami Valley and the I-75 corridor is quietly turning into one of the state’s hottest economic zones, with a trio of counties clocking some of the fastest real GDP growth in Ohio in 2024.
Greene, Warren, and Butler counties all landed inside the state’s top 15 for year-over-year real GDP gains, according to new federal numbers. Neighboring Montgomery and Miami counties also grew, though at a slower clip, while Clark and Champaign slipped slightly into negative territory.
County-level real GDP figures from the U.S. Bureau of Economic Analysis show Greene County’s economy up 4.8%, Warren up 4.6%, and Butler rising 4.4%. Montgomery County grew 1.9% and Miami County 1.1%, while Clark County edged down 0.3% and Champaign County dipped 0.1%. Those rankings, and how local officials are reading them, were broken down by the Springfield News-Sun.
"GDP gives a useful big-picture sense of whether a local economy is expanding, shrinking, or standing still," Marlon Williams told the Springfield News-Sun. Greene County officials cite Wright-Patterson Air Force Base and the surrounding defense-contracting ecosystem as a key engine behind their numbers. They also point to stronger household spending and a growing professional-services presence in suburban corridors as factors that helped lift the county in the BEA rankings.
Big Projects, Jobs And Visitor Dollars
In Warren County, the GDP bump lines up with some big development bets along I-75, including the $200 million Renaissance Pointe mixed-use project in Middletown. The project broke ground in June 2024 and is slated to bring new retail, hotels and an event center to the area. The cost, timing, and ongoing funding debates around the project were reported by the Journal-News, which has also detailed how local officials expect it to juice sales and lodging tax receipts.
A Mixed Statewide Picture
Statewide, the latest county numbers tell a split-screen story. Data from BEA and Ohio analysts show growth tending to cluster in counties that have significant government, defense, or major development footprints. Smaller or more manufacturing-dependent counties, on the other hand, were more likely to lag or tread water.
Those county-by-county tables are doing double duty as both a scoreboard and a planning tool. They backstop local reporting and give city halls, development offices, and business groups a way to see whether big-ticket investments are actually turning into jobs and household spending. Detailed breakdowns are available in the BEA release and the Ohio Office of Research summary.
What comes next is the real stress test: whether Renaissance Pointe and other I-75 corridor projects deliver the jobs and visitor spending that have been promised, and whether slower-growth counties can claw back momentum through federal contracts or targeted development. For now, the BEA’s county release remains the most granular public yardstick for seeing how those bets play out year after year.
