1. Start with Brentwood’s actual service footprint
The Census records Brentwood city as a municipality in Williamson County and reports a 2020–2024 ACS 5-year population estimate of 45,556, with a margin of error of 52. This is useful geographic context, not a forecast of inquiries. A firm may serve Brentwood residents, people working there, clients elsewhere in Williamson County, or a broader Tennessee area. Those are different audiences. Before configuring answering rules, define which callers your firm accepts and which locations or practice areas require a different response.
Recommended approach
Map your service area by practice area rather than treating Brentwood as a proxy for demand. Review recent call records by caller location, matter type, business hour, and disposition. Then decide whether the system should collect every inquiry, screen out defined categories, or route selected calls to a person. Keep the location language in your phone profile accurate and limited to the communities your firm actually serves.
