Census Merged Ward Boundaries for England and Wales, December 2011

England and Wales digital vector boundaries for Census Merged Wards as of 31 December 2011. The dataset contains three boundary resolutions: full extent (93 MB), generalised 20m clipped (10 MB), and super generalised 200m clipped (3 MB). It is provided by the Office for National Statistics under the OGL-UK-3.0 license.

Use Cases

• Mapping administrative boundaries based on the provided vector geometry files.
• Conducting spatial joins with census data based on the ward geography.
• Performing cartographic analysis using the different generalised boundary resolutions (20m, 200m).
• Integrating ward-level geography into regional planning or policy models.

Strengths
