This dataset contains gridded human population with a spatial resolution of 1 km x 1 km for the UK based on Census 2021 (Census 2022 for Scotland) and Land Cover Map 2021 input data. Data on population distribution for the United Kingdom is available from statistical offices in England, Wales, Northern Ireland and Scotland and provided to the public e.g. via the Office for National Statistics (ONS). Population data is typically provided in tabular form or, based on a range of different geographical units, in file types for geographical information systems (GIS), for instance as ESRI Shapefiles. The geographical units reflect administrative boundaries at different levels of detail, from Devolved Administration to Output Areas (OA), wards or intermediate geographies. While the presentation of data on the level of these geographical units is useful for statistical purposes, accounting for spatial variability for instance of environmental determinants of public health requires a more spatially homogeneous population distribution. For this purpose, the dataset presented here combines 2021/2022 UK Census population data on Output Area level with Land Cover Map 2021 land-use classes 'urban' and 'suburban' to create a consistent and comprehensive gridded population data product at 1 km x 1 km spatial resolution. The mapping product is based on British National Grid (OSGB36 datum).

Electoral Wards/Divisions are the key building blocks of UK administrative geography. They are the spatial units used to elect local government councillors in metropolitan and non-metropolitan districts, unitary authorities and the London boroughs in England; unitary authorities in Wales; council areas in Scotland; and district council areas in Northern Ireland.

The Wards and Electoral Divisions list contains 9,481 areas of the following constituent geographies:

• 7,218 Census Wards in England
• 453 Census Electoral Divisions in England
• 7 Census Merged Wards in England
• 582 Census Wards in Northern Ireland
• 353 Census Wards in Scotland
• 856 Census Electoral Divisions in Wales
• 12 Census Merged Wards in Wales

The boundaries are available as either extent of the realm (usually this is the Mean Low Water mark but in some cases boundaries extend beyond this to include off shore islands) or

clipped to the coastline (Mean High Water mark).

This dataset is part of the Geographical repository maintained by Opendatasoft. This dataset contains data for wards/electoral divisions in the United Kingdom.Electoral wards (and electoral divisions) are the key building blocks of UK administrative geography. They are the spatial units used to elect local government councillors in metropolitan and non-metropolitan districts, UAs and the London boroughs in England; UAs in Wales; council areas in Scotland; and local government districts (LGD) in Northern Ireland. Electoral wards are found in Scotland, Wales, Northern Ireland and most of England. In the Isle of Wight and several of the UAs created as part of the Local Government Reorganisation in 2009, the equivalent areas are legally termed 'electoral divisions', although they are frequently referred to as wards. Wales changed to using the term 'electoral wards' instead of 'electoral divisions' in August 2013.The only part of the UK without electoral wards/divisions is the Isles of Scilly, which has its own council but no electoral zoning. For statistical purposes, however, ONS treats the islands' five parishes as electoral wards. Electoral wards/divisions (and the Scilly parishes) cover the whole of the UK; in addition, all higher administrative units are built from whole electoral wards/divisions. They are also used to constitute a range of other geographies such as the Eurostat Nomenclature of Territorial Units for Statistics (NUTS) geographies, health geographies and Westminster parliamentary constituencies. Electoral ward/division boundary changes are usually enacted on the first Thursday in May each year, to coincide with the local government elections.Processors and tools are using this data.EnhancementsAdd ISO 3166-3 codes.Simplify geometries to provide better performance across the services.Add administrative hierarchy.
