Use Barstow as a defined service area, not a population proxy
The Census record identifies Barstow city and its relationship to San Bernardino County. It does not establish how many people search for a lawyer, which legal problems they have, or whether a particular query is commercially viable. For your firm, that distinction matters. A Barstow page should reflect the services you actually accept and the geographic relationship you can explain to a prospective client. If your intended footprint is broader than Barstow city, decide whether San Bernardino County is the appropriate boundary or whether only selected cities or counties belong in the structure.
Recommended approach
Ask Bosseo to review your current service areas against a proposed Barstow and county-level footprint. Treat the Census geography as a way to name and organize locations, then use your firm’s actual intake boundaries and legal services to decide what should be covered.
