Start with the Darby service boundary
Darby borough is a municipality in Delaware County, Pennsylvania. That distinction matters when you review attribution: a record associated with a Darby page, a person located in Darby and a matter your firm serves across Delaware County are not automatically the same geographic category. The local population estimate—10,687 for 2020–2024 ACS, with a margin of error of 21—can help define the market you are evaluating, but it cannot establish demand, competition, call volume, language preference, case volume or revenue. A useful attribution design therefore preserves the geographic detail that your firm actually needs rather than collapsing every inquiry into “Darby.”
Recommended approach
Decide which geographic fields matter to intake and reporting: municipality, county, service area, landing-page location and the location confirmed during qualification. Ask for a review of how those fields would be separated in a lead journey and how ambiguous or incomplete location information would be handled.
