1. Start with San Carlos as a service boundary, not a demand forecast
The U.S. Census Bureau records San Carlos as a municipality in San Mateo County and estimates its 2020–2024 population at 29,614, with a margin of error of 46. Those distinctions matter when you decide whether the widget should be presented to San Carlos visitors only or to a broader service area.
Recommended approach
Define the geographic questions before choosing routing rules. Decide whether San Carlos is a target location within a larger San Mateo County practice area, whether location affects eligibility, and whether a visitor’s address should trigger review by a particular attorney or office.
