It is a large Parliamentary Constituency including most of the local government district of East Cambridgeshire and about a third of South Cambridgeshire.
The large rural area belies its nature, not least because within the constituency are a number of centres of excellence in high tech research and manufacturing. Almost all the Cambridge Science Park is within South East Cambridgeshire as is the Cambridge Research Park at Landbeach. It also contains most of Cambridge Airport.
Agriculturally the constituency is largely arable being mainly cereals and sugar beet on the lighter chalk soils in the south whilst in the northern Fen areas intensive salad, vegetable and root cropping predominate. The constituency is one of the most important horse racing constituencies in the country; it includes the July Course at Newmarket and the point-to-point course at Horseheath. Most of the Stud farms that surround Newmarket, including the National Stud, lie within the constituency making the welfare of the racing industry of crucial importance to local employment.
At the time of the last General Election in 2010 the total electorate was 83,063. The result was the election for his sixth term of Jim Paice, the Conservative Candidate with a majority of 5,946.
