1. Start with Napa’s actual geographic boundary
Napa is a municipality in Napa County, California. The 2020–2024 American Community Survey 5-year estimate records 78,239 residents for Napa city, with a margin of error of 71. That figure establishes the geography and population measure; it does not establish legal demand, search volume, competition, call volume or the number of qualified inquiries available to a firm. It also does not describe all of Napa County or every person a firm may serve.
Recommended approach
Before reviewing attribution, decide which geographic relationships matter to your practice: Napa city, Napa County, or a broader service area. Ask whether reports should distinguish a landing page’s location from a prospective client’s location, and whether a case should be assigned by the firm’s defined service area rather than by population assumptions. Those definitions will make later channel and outcome comparisons more meaningful.
