1. Start with the Fairfax service area, not a population forecast
Fairfax is recorded as a municipal town in Franklin County, Vermont. The 2020–2024 ACS five-year estimate records 5,226 residents, with a margin of error of 23. That is useful geographic context when you define the calls your firm intends to serve, but it cannot tell you how many people will call, which practice areas they need, when they will call or whether they will hire your firm.
Recommended approach
Define your intended answering boundary in firm terms: Fairfax, Franklin County and any additional Vermont locations or service areas your firm actually handles. During a Bosseo review, compare that boundary with your existing phone greeting, consultation rules and conflict-screening requirements. Review actual unanswered calls, after-hours inquiries and overflow periods before deciding what coverage is appropriate.
