1. Start with Blackhawk’s actual service boundary
The 2020–2024 ACS five-year population estimate is 10,137, with a margin of error of 958. Your attribution plan should therefore distinguish Blackhawk inquiries from inquiries elsewhere in Contra Costa County and from broader California activity. Check whether your records can identify the geography associated with each inquiry without treating a place name as a legal qualification.
Recommended approach
Agree on the geographic labels you want to review before judging marketing. At minimum, decide how Blackhawk, Contra Costa County and other service areas will be separated in intake and reporting. Then review whether landing-page, referral and intake records preserve that distinction.
