If you want to understand Delaware County right now, don’t look at a single number. Look at the direction of the numbers.
The latest projections from the Delaware County Regional Planning Commission show a county that is not just growing, but continuing to reshape itself — unevenly, rapidly in some places, and almost imperceptibly in others. By the start of 2026, Delaware County is projected to reach 250,509 residents, up from 214,124 in 2020. That’s a 17.0% increase in just six years — a pace that would be remarkable anywhere, but especially in a county that was already one of Ohio’s fastest-growing.
What’s striking is not just the growth itself. It’s where that growth is happening.
The Outer Ring Is Leading the Surge
The biggest story in these projections sits just outside the traditional population centers. Berkshire Township is expected to grow by 74.8% between 2020 and 2026, reaching 7,826 residents. Berlin Township follows with a projected 44.6% increase, and Liberty Township adds another 35.1% on top of already substantial growth.
Even more telling is the annualized growth rate. Berkshire Township is projected at 7.5% per year, and Berlin at 4.5%. Those are not incremental changes. Those are transformation-level numbers.
Meanwhile, some of the county’s long-established townships are barely moving. Genoa Township, already built out in many areas, is projected to grow just 2.6% from 2020 to 2026. In other words, the center of gravity is shifting.
Cities Are Growing, But Differently
Incorporated areas tell a more nuanced story. The City of Delaware continues steady expansion, projected to reach 49,020 residents — an 18.7% increase since 2020. That’s strong, consistent growth, reinforcing its role as the county’s anchor city.
But the fastest percentage gains are happening in smaller places. Galena is projected to grow by 72.0%, and Sunbury by 48.9% over the same six-year period. These are not just population increases. They represent a shift in where people are choosing to live — often driven by new housing, access to major corridors, and proximity to job centers further south. Even Columbus, within its Delaware County footprint, more than doubled between 2010 and 2020 and is still growing, though at a slower pace now.
At the other end of the spectrum, some communities are essentially flat. Dublin’s Delaware County portion is projected to grow just 1.6% from 2020 to 2026, and Ashley is expected to slightly decline.
A County Divided by Growth Patterns
Taken together, the numbers show a county splitting into three distinct growth patterns:
- High-growth frontier areas, where development is accelerating rapidly
- Established suburbs, where growth is slowing as space tightens
- Stable or slow-growth communities, where change is modest or even negative
Total township population is projected to grow 17.8%, while incorporated areas grow 16.0%. On paper, those numbers look similar. On the ground, they feel very different.
What This Means Going Forward
There’s a temptation to look at these numbers and simply say, “Delaware County is growing.” That’s certainly true. At the same time, growth is becoming more directional, more concentrated, and more consequential. Infrastructure, schools, water systems, and land use decisions will all be different, and they will be tested hardest in the places growing the fastest — often the same places still building out their identity.
At the same time, slower-growth areas will face a different question: how to remain competitive and relevant in a county where momentum is clearly shifting elsewhere. The projections don’t predict policy decisions or community reactions. But they do something just as important. They show, with unusual clarity, where the future is already arriving.
