1. Start with Duluth’s actual service area, not a population assumption
Duluth is a municipality in St. Louis County, Minnesota. The 2020–2024 ACS five-year estimate records 87,093 residents, with a margin of error of 127. That is geographic and eligibility context, not evidence of legal demand, search volume, competition, call volume or likely revenue. For attribution, the important local question is how your firm defines a qualified matter: Duluth only, St. Louis County, a broader Minnesota practice area, or another arrangement. A source record is useful only when the firm applies a consistent definition of a qualified inquiry and signed case.
Recommended approach
Before reviewing channel performance, write down the geographic boundaries and matter types your intake team will use. Ask whether a Duluth page, a county page, a referral, an AI referral, an organic result or a Local Services Ad should be evaluated against the same qualification standard. Do not use the population figure as a forecast.
