Census 2024 Adrian Frithen. There’s one site for the 2011 census, and another site (with not so many features) for the 2001. Population statistics were obtained from the census.

Note that some 800,000 people living in institutional settings were not asked about their languages and are not included here. Under this system there are a fixed number of 300 seats for constituency mps, which are allocated to constituencies in proportion to the size of the constituency voters’ roll.
