Bearsden is an affluent middle class commuter town serving Glasgow, which explains why levels of owner-occupation are so high (76.8%) and professionals and managers so numerous (44.6%) within the constituency.
But the political heart of this seat is in the Labour-friendly towns of Bishopbriggs and Kirkintilloch. These were once centres for coal mining and metal founding industries, but most of those heavy industries have been gone since the 1930s.
The main industries now are book publishing, construction, transport and agriculture with a growing number of firms in the light industrial sector.
Dr Sam Galbraith won the seat for Labour from Conservative Sir Michael Hirst in 1987 and it remained a Labour/Conservative marginal at the 1992 general election. However, boundary changes in 1997 made this seat safer for Labour.
There is some history of SNP representation - its predecessor seat East Dunbartonshire was held by Margaret Bain (now Margaret Ewing) from October 1974 to 1979, but the SNP was in third place behind the Conservatives in 1997.
