Census Merged Local Authority Districts: 2011 Boundaries for England and Wales

December 2011 digital vector boundaries for Census Merged Local Authority Districts in England and Wales. The dataset provides two generalised versions of the boundaries, both clipped to the Mean High Water coastline mark. It contains intellectual property rights from both the Ordnance Survey and the Office for National Statistics.

Use Cases

• Mapping census data for England and Wales based on the 2011 administrative geography.
• Performing spatial analysis using generalised boundaries for computational efficiency.
• Creating visualizations for regional planning and resource allocation using the clipped coastline boundaries.

Strengths

• Provides two levels of boundary generalisation (20m and 200m) for different use cases.
• Contains intellectual property from authoritative sources (Ordnance Survey and ONS).
• Boundaries are clipped to the coastline (Mean High Water mark) for accurate coastal representation.

Limitations

• Dataset is specific to a single snapshot date (31 December 2011) and does not reflect subsequent boundary changes.
• Column names and detailed attribute data are not described in the provided metadata.
• The 'last updated' metadata field (2026-07-08) appears to be a platform artifact and does not reflect a substantive data update.
