1. Start with the geography your firm actually serves
The U.S. Census Bureau records Londonderry as a census-designated place in Rockingham County, New Hampshire, with a 2020–2024 ACS five-year population estimate of 12,225 and a margin of error of 674. That is population context only. It does not establish legal demand, search activity, competition, lead volume or revenue. For attribution, the important implementation choice is to define the geographic scope of the records you want to evaluate: Londonderry alone, Rockingham County, or a broader New Hampshire service area. Households, individuals and geographic areas should not be treated as interchangeable.
Recommended approach
Bring a written service-area definition to the consultation. Decide whether location should be recorded as an intake answer, reviewed through landing-page paths, or assessed alongside the matter type. Keep Londonderry and Rockingham County distinct when comparing performance so a local observation does not become an unsupported demand claim.
