The Representation of the People Act 1918 brought constituency boundaries generally into alignment with local government boundaries established under the Local Government (Scotland) Act 1889 and subsequent related legislation, but there were later changes to local government boundaries which were not reflected in new constituency boundaries until 1950, the same year that the Dunbartonshire constituency was abolished, under the House of Commons (Redistribution of Seats) Act 1949.
For the 1708 (first) general election and every subsequent election of the Parliament of Great Britain the Dumbartonshire constituency consisted of the county of Dumbarton minus the burgh of Dumbarton, which was a component of the Clyde Burghs constituency.
