Put Birch Bay geography in the right place
Birch Bay is recorded by the U.S. Census Bureau as a census-designated place in Whatcom County, Washington. The 2020–2024 ACS five-year population estimate is 10,837, with a margin of error of 1,030. That is geographic and population context, not evidence of legal demand or a forecast of leads. Attribution should therefore not begin with an assumption that a population figure predicts case volume. It should begin with a clear definition of the inquiries your firm considers relevant to Birch Bay and how those inquiries are identified in your records.
Recommended approach
During a consultation, define whether Birch Bay is tracked as a service-area label, an address or residence field, a landing-page geography, or another firm-approved category. Keep that choice separate from channel attribution so you can ask two different questions: where did the inquiry originate, and does it belong to the Birch Bay service area?
