1. Start with the geography you actually serve
The 2020–2024 ACS five-year population estimate is 5,836, with a margin of error of 282. Your first decision is therefore operational: can your firm serve clients in Millersville, and which surrounding county relationships belong in the planned footprint?
Recommended approach
Treat Millersville, Robertson County, and Sumner County as separate geographic choices. Confirm the locations your attorneys accept, the courts or agencies relevant to your services, and whether a city-level page should link to broader county or state coverage.
