This file is a best fit lookup between 2011 lower layer super output areas, electoral wards/divisions and local authority districts in England and Wales as at 31 December 2021 (File Size - 7 MB)
Version 2 produced so that W01000060 - Gwynedd 015B population weighted centroid falls right on the border and now due to Ordnance Survey realigning the ward and local authority boundary we have reallocated the population weighted centroid so it falls in W05000056 - Corris/Mawddwy and W06000002 - Gwynedd.
