Constituencies of the Parliament of the United Kingdom

The table below gives the number of eligible voters broken down by constituent country, including the average constituency size in each country. As of 2023, every recommended constituency must have an electorate as at 2 March 2020 that is no smaller than 69,724 and no larger than 77,062. The exceptions to this rule are five 'protected' constituencies for island areas: Orkney and Shetland, Na h-Eileanan an Iar, Ynys Mon, and two constituencies on the Isle of Wight. These consequently have smaller electorates than the lower limit for other constituencies. Geographical size of constituencies As the number of electors in each constituency is similar, the constituencies themselves vary considerably in area, ranging in 2019 from Ross, Skye and Lochaber, which occupies a sixth of Scotland, to the densely populated London constituency of Islington North. ==Parliamentary constituencies in the United Kingdom==
