Derry and Rockingham County
Derry is associated with Rockingham County in the Census boundary data. Start with the parcel’s tax bill to match the property to that jurisdiction, then confirm which government handles its land use.
Derry by land and water
The Census records 0.82 square miles of water within Derry, or 2.3% of its total area. It is 10.3 percentage points lower than the 12.5% recorded for Rockingham County. This is geographic context; waterfront status and usable land must be checked at the parcel.
For scale, Derry town has 2.9 times the land area of nearby Londonderry CDP (12.2 square miles). These areas describe boundaries, not comparable property prices.
