Start with Durham’s actual service boundary
The U.S. Census Bureau records Durham as a municipal town in Connecticut. Its 2020–2024 ACS five-year population estimate is 7,208, with a margin of error of 31. The same record places Durham in the Lower Connecticut River Valley Planning Region. Those facts describe the town and its recorded geographic relationship; they do not establish legal demand, call volume, competition, language preference or staffing requirements. For your firm, the practical use of this geography is to define which callers and matters belong in the intake path you want to review.
Recommended approach
Write down whether your phone response is intended for Durham alone, the Lower Connecticut River Valley Planning Region, or a broader Connecticut service area. Then decide how the answering system should classify callers who are outside your accepted geography. That boundary should be part of the firm profile reviewed during a Bosseo consultation, rather than inferred from population.
