Durham in numbers

Durham had 15,264 residents in the state's 2025 estimate, up 4.3% from 14,638 in 2010, slower than the state's 7.5%. Since the 2020 census the count has slipped 1.5%. Its density of 677 people per square mile puts it 9 of 19 among the towns on this site. 6,925 of those residents (45.4%) live in group quarters such as dormitories or care homes, so fewer people live in owner-occupied houses than the headline count suggests.

64.4% of Durham's occupied homes are lived in by their owners, fewer than the 72.8% statewide, and the median owner-occupied home is valued at $504,300 (New Hampshire: $402,500).
