List of United Kingdom Parliament constituencies (1918–1945) by region

Between 1918 and 1945, the parliamentary constituencies of the United Kingdom were defined primarily by the Representation of the People Act 1918, which restructured the electoral system in response to post-war social and demographic changes. The Act enfranchised all men over the age of 21 and women over 30 who met minimum property qualifications, significantly expanding the electorate. It also redrew constituency boundaries to reflect population growth and urbanisation following the First World War. ^[1]

This period saw seven general elections, from 1918 to 1935, conducted using these boundaries. The constituencies remained largely unchanged until the implementation of the Representation of the People Act 1948, which introduced single-member constituencies and equal representation by population, effective from the 1950 general election. ^[2] The political implications of these reforms, and the evolving role of Parliament during this time, have been analysed by scholars such as Vernon Bogdanor, ^[3] and documented in reference works by David and Gareth Butler. ^[4]
