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. 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.
