 In common with metropolitan areas the seat saw major population increase and was weighty from the outset in terms of population in 1885.Until 1918 it included Chiswick, Acton within the County of London, and part of Hanwell in the rump of dwindling Middlesex.The constituency was created by the Redistribution of Seats Act 1885 for the 1885 general election, and abolished for the 1945 general election.
