1. Start with Blackhawk’s actual service boundary
Blackhawk is a CDP in Contra Costa County, not a synonym for every household, person or community in the county. The Census estimate of 10,137 describes the Blackhawk CDP for the 2020–2024 ACS 5-year period. It does not show how many people contact law firms, where callers search, which practice areas they need or whether your firm has missed calls from the area.
Recommended approach
Use Blackhawk as a defined service location when reviewing your phone records and intake policy. Separate calls from Blackhawk from calls elsewhere in Contra Costa County and from other California locations. This keeps the evaluation tied to observed caller geography rather than turning a population estimate into a demand forecast.
