Wales Electoral Region Boundaries: 2016 Vector Data

As of 31 December 2016, this dataset provides digital vector boundaries for the National Assembly for Wales Electoral Regions. It contains four boundary variants, including full-resolution and generalised versions clipped to the coastline. The data is published by the Office for National Statistics and contains both Ordnance Survey and ONS intellectual property rights.

Use Cases

• Mapping electoral regions for political analysis based on the provided vector boundaries.
• Integrating administrative boundaries into GIS systems using the available ArcGIS REST services.
• Creating generalised maps for publication using the 20m or 200m simplified coastline-clipped versions.

Strengths

• Provides four specific boundary variants with explicit file sizes (e.g., 2 MB for full resolution).
• Contains intellectual property rights from two authoritative sources: Ordnance Survey and the Office for National Statistics.
• Offers multiple access methods, including direct download and ArcGIS REST services for INSPIRE compliance.

Limitations

• Key metadata such as row count, column names, and specific author are not provided in the sources.
• The dataset is static and reflects a single snapshot from the end of 2016, limiting analysis of boundary changes over time.
• Platform metadata shows conflicting 'last updated' timestamps (e.g., 2026-07-08), which is inconsistent with the 2016 data content.
