The constituency covers the major town of Kettering, the smaller towns of Desborough, Rothwell and Burton Latimer together with a number of villages. A semi-rural seat, the preponderance of constituents live in the towns and a minority of the wards form a wide array of rural communities that have civil parish or hamlet status.

The constituency created in 1918 included the generally (in the late 20th century) Labour-majority industrial town of Corby until the 1983 general election, when Corby gained its own constituency.

The Boundary Commission's Fifth Periodic Review of Westminster constituencies proposed an additional seat due to population growth in the county. Parliament approved its recommendations for 2010 which made way for the new constituency of South Northamptonshire therefore the constituency lost some wards in these boundary changes.^{[n 3]}

Economically, it is predominantly middle-class, well within managerial/directorial commuter zones for London and the West Midlands. Industry continues in some sectors ranging from, for example, lingerie,^[3] food production, rigid containers, abattoirs, to the Weetabix factory in Burton Latimer, but the industrial activity of the area, as with the rest of the county, is reduced whereas the wider area's headline gross value added for the area per head has been mostly consistently higher, from £11,667 in 1997 in North Northamptonshire to £17,835.^{[n 4][4]}

In 2005 The Guardian described it as:

'[A] mixed industrial town in Northamptonshire with good links to London.'

The current Member of Parliament is Philip Hollobone of the Conservative Party. He was elected in 2005 when he defeated the sitting Labour MP, Phil Sawford, in an election which nationally saw a reduced majority for the Blair Ministry.
