1. Start with Brentwood call coverage—not a population assumption
The Census records Brentwood as a municipality in St. Louis County, with an estimated population of 8,144 for 2020–2024. For your decision, the useful local question is narrower: which calls from people seeking your firm go unanswered, and what should happen next?
Recommended approach
Review call records by time, outcome and caller type. Separate voicemail, abandoned calls, current-client calls and potential new-client calls. Then decide whether Brentwood should be handled as its own service area or as part of your broader St. Louis County intake approach.
