1. Start with the North Berwick service area, not a population assumption
The Census record identifies North Berwick as a municipal town in York County, Maine, and reports a 2020–2024 ACS 5-year population estimate of 5,129, with a margin of error of 22. That establishes a geographic context for a firm serving North Berwick; it does not establish how many people search for legal help, how many competitors operate there, or how many inquiries your firm should expect. Attribution is useful here because it can distinguish the location you want to serve from the actual path an inquiry took. The relevant record may include a landing page, referrer, channel, device, intake answers and later outcome. That gives you evidence about your own inquiries rather than treating town population as a forecast.
Recommended approach
Define the geographic scope you want to evaluate—North Berwick, York County, Maine or another service area—and ask how each inquiry will be categorized. Keep the location definition separate from population, household and individual assumptions. Use the consultation to decide which geographic fields belong in reporting and which should remain descriptive only.
