Areas used to elect local authority councillors. The data are for wards as at May 2022, apart from two instances. We treat the City of London and the Isles of Scilly local authorities as single wards, not made up of multiple wards. We have also split the data for Hunmanby and Sherburn ward into Hunmanby and Sherburn (part Ryedale) and Hunmanby and Sherburn (part Scarborough). This is to reflect that the ward is split between two local authorities, Ryedale and Scarborough.
