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.
Recommended approach
Use the consultation to define which geography matters for measurement: Port Huron, 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.
