Great Britain Electoral Ward Boundaries from December 2015

Four versions of digital vector boundaries for electoral wards in Great Britain, including full-resolution and simplified (20m, 200m) versions clipped to the coastline. The data contains both Ordnance Survey and Office for National Statistics intellectual property rights and was last updated on the platform in July 2026. File sizes range from 3 MB for the super generalised version to 135 MB for the full-resolution clipped version.

Use Cases

• Create electoral maps for Great Britain based on the 2015 ward boundaries.
• Perform spatial joins with demographic data using the provided vector boundaries.
• Simplify complex boundary geometries for web mapping using the 20m or 200m generalised versions.
• Analyze coastal administrative extents using the boundaries clipped to the Mean High Water mark.

Strengths

• Provides four distinct boundary versions, including a lightweight 3 MB super generalised (200m) file.
• Includes both full-resolution extent-of-the-realm and coastline-clipped versions for different use cases.
• Contains intellectual property from two authoritative UK sources: Ordnance Survey and the Office for National Statistics.

Limitations

• Boundary data is from a single snapshot in December 2015; more recent administrative changes are not reflected.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale joins.
