United Kingdom electoral quota - Sixth Review
The United Kingdom electoral quota for the Review is the number obtained by dividing the total parliamentary electorate at 1 December 2010 for the United Kingdom by 596, excluding the electorates of Na h-Eileanan an Iar, Orkney Islands and Shetland Islands council areas, and the Isle of Wight. 596 is the number of constituencies outside those island areas. In simple terms, the United Kingdom electoral quota is the average electorate of mainland constituencies. The United Kingdom electoral quota for the Review is 76,641.2.
The electorate of each constituency, with a few specified exceptions, has to be within 5% of the United Kingdom electoral quota - that is, an electorate no fewer than 72,810 and no more than 80,473. The exceptions that can affect Scotland are that any constituency exceeding 12,000 square kilometres, and the constituencies covering Na h-Eileanan an Iar, Orkney Islands and Shetland Islands council areas, can have a smaller electorate.
