1. Separate Arlington activity from assumptions about demand
The U.S. Census Bureau records Arlington as the Arlington in Middlesex County, Massachusetts, with a 2020–2024 ACS five-year population estimate of 46,350 and a margin of error of 40. Ask whether your records can distinguish a person seeking service in Arlington from a visitor who merely viewed an Arlington-related page, and whether the matter was qualified, consulted on, or signed.
Recommended approach
Use Arlington as a defined service-area lens in your review, while keeping Middlesex County and any broader Massachusetts coverage distinct. Decide which geographic fields your team needs to review alongside source and matter outcome.
