Start with the geographic record, not a demand assumption
Oak Harbor is recorded in Island County, Washington. The 2020–2024 ACS five-year population estimate is 24,362, with a margin of error of 29. For an Oak Harbor firm, the practical attribution question is narrower: can you distinguish inquiries associated with Oak Harbor from other geographic service areas, and can you connect those inquiries to qualification and outcome records without asking your team to reconstruct the path later?
Recommended approach
Use Oak Harbor and Island County as explicit geographic labels in your review of incoming inquiries. Then decide which additional service areas, practice areas and referral sources need separate reporting. Use actual records to assess inquiry quality, ownership and progression.
