1. Start with Hanover’s actual service geography
Hanover is recorded by the U.S. Census Bureau as a census-designated place in Grafton County, New Hampshire. The 2020–2024 ACS five-year population estimate for Hanover CDP is 8,479, with a margin of error of 350. That is geographic and population context, not evidence of legal demand, competition, search activity, calls or revenue. Your attribution design should therefore preserve the distinction between a person’s location, the area your firm serves and the source that brought the inquiry to your firm. A Hanover inquiry should not automatically be treated as a Grafton County inquiry, and a county relationship should not be used to infer where a prospective client searched or why they contacted you.
Recommended approach
Define the service-area fields and reporting labels you actually need before evaluating performance. Review whether the intake record can distinguish Hanover from other Grafton County locations and from broader New Hampshire inquiries. Then decide whether location should support routing, qualification or reporting rather than being used as a proxy for demand.
