The Glasgow Cathcart constituency was created at the same time as the Scottish Parliament, in 1999, with the name and boundaries of an existing Westminster constituency. In 2005, however, Scottish Westminster (House of Commons) constituencies were mostly replaced with new constituencies.
The Holyrood constituency is entirely within the Glasgow City council area, on the area's southern boundary. It is east of the Pollok constituency, south of Govan and Shettleston and west of Rutherglen.1.
The Pollok and Shettleston constituencies are also entirely within the city area.
The Govan constituency includes a small eastern portion of the Renfrewshire council area. The Rutherglen constituency includes a north-western portion of the South Lanarkshire council area.
