Census Merged Local Authority Districts in Great Britain, 2011 Boundaries

December 2011 digital vector boundaries for Census Merged Local Authority Districts in England and Wales, created by the Office for National Statistics. The dataset contains two versions of boundaries clipped to the coastline: generalised (20m) and super generalised (200m). It includes intellectual property from both Ordnance Survey and the ONS.

Use Cases

• Create thematic maps of census statistics based on merged local authority district boundaries.
• Perform spatial joins between census data and administrative units using the provided vector boundaries.
• Generate simplified, coastline-clipped maps for visualization using the super generalised (200m) version.

Strengths

• Provides two levels of geometric detail: generalised (20m) and super generalised (200m) boundaries.
• Boundaries are clipped to the coastline (Mean High Water mark), ensuring accurate coastal representation.
• Contains intellectual property from authoritative sources: Ordnance Survey and the Office for National Statistics.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is specific to a single snapshot date (31 December 2011), limiting temporal analysis.
• Row count is unknown, which may limit suitability assessment for large-scale processing.
