1. Separate Millersville activity from the wider service area
The U.S. Census Bureau records Millersville borough as a municipality in Lancaster County, Pennsylvania, with a 2020–2024 ACS five-year population estimate of 8,982 and a margin of error of 24. That figure describes the borough’s population estimate; it does not establish legal demand, search behavior, competition, lead volume or revenue. Attribution therefore should not treat “Millersville” as a proxy for every person or household in Lancaster County. A useful review asks how location is represented in the journey: landing page, intake answer, call record or another field available to the firm. It also asks whether a matter is associated with the borough, the county, another Pennsylvania location or an area that cannot be determined from the record.
Recommended approach
Review geographic fields before using local data in a budget decision. Define the locations your firm actually wants to compare, keep Millersville borough distinct from Lancaster County and Pennsylvania, and mark unknown geography as unknown rather than forcing a location label.
