1. Start with Lisbon’s actual geographic scope
The 2020–2024 ACS 5-year population estimate is 10,736, with a margin of error of 49. It also should not be treated as a count of households, inquiries, or potential clients. For attribution, the useful question is narrower: how will your firm distinguish an inquiry associated with Lisbon from one associated with another place you serve?
Recommended approach
Define the geographic labels your intake and reporting use before judging channel performance. Review whether the location is captured from the person’s answers, the relevant landing page, the matter record, or another source. Use observed inquiries and documented outcomes instead.
