The constituency contains the town of Arundel and villages and hamlets within the South Downs national park boundaries or encircled by the park, the largest of which are Hassocks, Hurstpierpoint, Petworth, Pulborough, Steyning and Storrington.
Following their review of parliamentary boundaries in West Sussex which Parliament approved in 2007, the Boundary Commission for England formed new constituencies. First contested in 2010 the seat was constituted as follows:
|Wards of the United Kingdom||In district/borough of:|
|Angmering, Arundel, Barnham, Findon, and Walberton||Arun|
|Bury, Petworth, and Wisborough Green||Chichester|
|Bramber, Upper Beeding and Woodmancote, Chanctonbury, Chantry, Cowfold,Partridge Green, Shermanbury and West Grinstead, Henfield, Pulborough and Coldwaltham, and Steyning||Horsham|
|Hassocks, and Hurstpierpoint and Downs.||Mid Sussex|
In their recommendations, the Boundary Commission for England mooted the name Chanctonbury after uninhabited Chanctonbury Ring, an ancient hill fort at its centre. This name was rejected during the local inquiry process at which the current name was chosen.
The 2017 result saw the sixth Conservative win.
Second-place runners-up have been, listed in order, four times a Liberal Democrat, once the UKIP candidate and once the Labour candidate. In line with regional trends, the highest percentage of the vote among these was the Liberal Democrat in 2010, with 27.9% of the vote.
In June 2016, an estimated 50.3% of local adults voting in the EU membership referendum chose to remain in the European Union instead of to leave. This was defied in two January 2018 votes in Parliament by its MP, in line with his governing party's promise to adhere to the overall result of that referendum.
The 2015-2017 status was as the 8th safest of the Conservative Party's 331 seats by percentage of majority.
The incumbent Howard Flight MP had national media coverage in the run-up to the 2005 general election due to his deselection requested by the party leader for membership of Conservative Way Forward, lobbying for spending cuts to be more severe than set out in the small cuts in the 2005 manifesto. Flight hinted his preferred cuts would be as implemented by a Conservative government in his view. He had represented the constituency since its creation at the 1997 general election. Anne Marie Morris, Laura Sandys and Nick Herbert put themselves forward for nomination as replacement candidates. The chosen candidate, Nick Herbert, won the seat at the election. Morris and Sandys became MPs elsewhere in 2010.
The seat and its predecessors have in the 20th century been a Conservative Party stronghold save that the minor contributory Horsham seat to the area's electorate saw victory by 8.6% of the vote over the Labour Party in 1966, followed statistically by a next-most-marginal victory again with the Labour Party as runner-up, in 1950, of 14.4%.
Between 1974 and 1983, much of the South Downs area was part of the Shoreham constituency, with the town of Arundel remaining in the Arundel constituency.
Prior to 1974, the seat was largely part of the Arundel and Shoreham constituency.
