1. Start with Umatilla coverage, not a population forecast
The Census record identifies Umatilla city as a municipality in Umatilla County. Its 2020–2024 ACS 5-year estimate is 7,508 people, with a margin of error of 21. That fact helps define the place your firm serves; it does not establish how many people call a law office, how often calls arrive outside business hours or whether your team needs additional coverage. Do not use the population figure as a substitute for your own phone records. Review unanswered calls, voicemail messages, after-hours inquiries and busy-period call patterns before deciding what needs to change.
Recommended approach
Bring a defined service area and a representative view of your existing call handling to the consultation. Ask whether the proposed response path fits calls from Umatilla and the rest of Umatilla County without treating either geography as proof of demand. The practical question is whether a missed caller receives a useful next step, not whether a city population implies a certain number of cases.
