Start with the service area you actually serve
Durham is recorded as a census-designated place in Strafford County, New Hampshire. The 2020–2024 American Community Survey 5-year population estimate for Durham CDP is 10,681, with a margin of error of 508. That figure describes the Durham CDP population; it does not establish legal demand, search volume, competition, lead volume or revenue. For reputation work, the more useful question is geographic coverage: does your Google Business Profile and review activity accurately support the towns, county relationships and broader New Hampshire service area your firm is prepared to serve?
Recommended approach
Map the geographic language used in your profile, website and review-request communications before deciding how broadly to run the program. Keep Durham distinct from Strafford County, New Hampshire and any metropolitan area you may serve. Review whether prospective clients can understand where the firm practices without using population as a proxy for demand.
