Start with the geography your firm actually serves
Rancho Cucamonga city is a municipality in San Bernardino County, California. The 2020–2024 ACS five-year population estimate for the city is 175,411, with a margin of error of 81. That is context for defining a service area, not evidence of legal demand, search volume, competition, lead volume, staffing needs, or revenue. Attribution should therefore preserve the distinction between a Rancho Cucamonga inquiry and a broader San Bernardino County inquiry. If your firm serves both, review those geographies separately instead of treating every local contact as one market.
Recommended approach
At consultation, decide which geographic labels matter to your firm: Rancho Cucamonga city, San Bernardino County, California, or another service boundary you already use. Then ask to review whether the available journey and intake records can support those distinctions. Do not use the city population as a forecast.
