1. Start with the Upper Arlington service area, not a population forecast
Upper Arlington is recorded in Franklin County, Ohio. The 2020–2024 ACS five-year population estimate is 36,293, with a margin of error of 47. For attribution, the practical implication is narrower: define the geographic scope of the records you want to inspect. Decide whether your review concerns Upper Arlington alone, Franklin County more broadly, or both. Then ask whether your reporting can distinguish the relevant service area from other places your firm serves.
Recommended approach
Use Upper Arlington as a defined review scope rather than as a forecast. In a consultation, identify the local pages, campaigns, referrals and intake records you want to compare, and agree on how a qualified inquiry and a signed case will be recognized.
