The constituency boundaries roughly correspond with the Malvern Hills District. The seat is known for its hilly landscape: with products such as regional speciality cheeses, drinks and mineral water, a major economic sector is tourism and leisure. However, the principal industries are in agriculture; food; chemicals; distribution; waste and mineral processing; printing and publishing; and transport and retail.

West Worcestershire formally, the Western division of Worcestershire, was created the first time for the 1832 general election, by the Reform Act 1832 which radically changed the boundaries of many British parliamentary constituencies. It was created by the division of the old Worcestershire constituency (which had existed since 1290) into two new two-member constituencies: West Worcestershire and East Worcestershire.
The seat was created on Parliament's approval for the 1997 general election of the Boundary Commission's fourth periodic review (following the first such review in 1945, which in turn followed that of the Representation of the People Act 1918.
In the four elections to date the seat has alternated between Conservative majorities that were quite marginal (7.8% and 5.3%) and those that were greater than 10%, at 12% and 12.7%, close to average in terms of security for any of the three largest parties. As never having had a majority that exceeded 15% of the vote (in this modern creation) and having had the two marginal majorities to date, the seat cannot be classified as safe.
The modern seat has had no notable frontbenchers but a notable parliamentarian in the backbenches. The MP for the seat from 1997 to 2010 was Sir Michael Spicer of the Conservative Party. He previously represented the former seat of Worcestershire South from 1974, and was chairman of the backbench 1922 Committee from 2001 until 2010 when he retired.
