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. The figure describes the city’s resident population; it does not show how many people search for legal help, how many matters fit your practice or how many website visitors will complete an intake. It also does not describe the wider county, nearby cities or a metropolitan area. 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. Treat the population estimate as context for market definition, not as a reason to predict lead volume or staffing.
