Start with the geography you actually serve
Port Huron is a municipality in St. Clair County, Michigan. The 2020–2024 American Community Survey five-year estimate records 28,620 residents, with a margin of error of 81. That figure describes the city population; it does not establish legal demand, search volume, competition, lead volume or revenue. It also does not describe every person or household your firm may serve in St. Clair County or elsewhere in Michigan. Attribution should therefore begin with your firm’s real service area and inquiry sources, not a population-based assumption about how many cases exist.
Recommended approach
Use the consultation to define which geography matters for measurement: Port Huron city, St. Clair County, other Michigan locations, or a combination. Then decide whether reporting should distinguish local landing pages, broader service pages, referrals and paid channels. Keep the geographic labels precise so a city result is not mistaken for a county-wide or statewide result.
