1. Start with the geographic record, not a demand assumption
Chelsea city is recorded in Washtenaw County. The Census estimate of 5,426 is useful for defining the place under discussion, but it cannot establish legal need, competition, search behavior, call volume or the number of prospective clients. A Chelsea service area may also involve people who contact a firm from outside the city, so a location label alone is not a reliable source of attribution. Your review should therefore separate geography from conversion evidence. Ask whether the journey record preserves the page, referrer, channel and inquiry details associated with a particular contact, rather than treating a city name as proof of marketing performance.
Recommended approach
Use Chelsea and Washtenaw County as explicit fields or review dimensions only where they are genuinely present in your intake and marketing records. Decide which geographic distinctions matter to case acceptance, and do not turn the Census population figure into a forecast.
