This large seat reaches to the Pennines and is traversed by Hadrian's Wall, which runs almost due east–west through England. It includes substantial agricultural holdings, forestry, wood processing, food, minerals, and manufactured hardware industries. It has been held by the Conservative Party and rarely with only marginal majorities since 1924. In the midst of the northwest of the area is Kielder Water and running between this area and the middle of the seat is the southern portion of Kielder Forest, and in the west, the attractions of the precipitous Haltwhistle Burn, Viaduct and Castle. SSE of Hexham is the Derwent Reservoir. As well as those rural areas, the constituency also includes part of Newcastle's middle-class suburbs. Hexham was the only Conservative seat in the North East between 1997–2010, and the only one in Northumberland from 1973 until the Conservatives won Berwick-upon-Tweed in 2015. Despite this middle-class population there are also some more working-class areas: Prudhoe frequently elects Labour councillors and has demographics similar to neighbouring parts of Blaydon, a safe Labour seat. There is also some deprivation in rural areas, particularly around Haltwhistle. Based on the latest published old age dependency ratios, a slightly larger proportion of the than the national average is retired. In 1997 the Labour Party nearly won the seat, but more usually Hexham is a safe seat for the Conservative party.
The constituency is named after the town of Hexham in Northumberland. It includes the former Tynedale district and part of the former Castle Morpeth district.
