Start with Derry’s actual geographic scope
Derry is recorded as a census-designated place in Rockingham County, New Hampshire. The 2020–2024 American Community Survey 5-year estimate records 21,339 residents, with a margin of error of 1,078. For reputation work, the important decision is how your firm defines its service area. A profile may be relevant to people in Derry, elsewhere in Rockingham County, or another area your firm serves. Those audiences should not be treated as interchangeable.
Recommended approach
Map the locations your firm actually serves before choosing review-request language or judging performance. Keep Derry, Rockingham County, New Hampshire, and any broader metropolitan coverage distinct in reporting.
