Start with the Mill Valley service area, not a population assumption
Mill Valley is recorded as a municipality in Marin County, California. The 2020–2024 ACS five-year estimate records 14,012 residents, with a margin of error of 26. That is geographic context, not evidence of legal demand, search volume, competition, lead volume, cases or revenue. It should not determine how many inquiries your firm expects or what questions every visitor should answer. It can, however, help you define the service-area language and routing decisions you want to review. If your firm serves Mill Valley as part of a broader Marin County practice, the intake should make the relevant location question explicit rather than treating every visitor as the same kind of matter.
Recommended approach
Review whether location belongs near the beginning of your intake, which locations require different ownership, and whether a Mill Valley visitor should follow the same path as another Marin County inquiry. Keep geographic qualification separate from legal eligibility and never use the population figure as a forecast.
