National Assembly for Wales Electoral Regions: Vector Boundaries as of December 2017

Digital vector boundaries for the National Assembly for Wales Electoral Regions, representing the administrative geography as of December 2017. The Government Digital Service provides this data, which is generalised to a 20-meter resolution and clipped to the coastline. Last updated on the platform in June 2023, the dataset contains both Ordnance Survey and ONS intellectual property rights.

Use Cases

• Create electoral maps for Wales based on the December 2017 boundary definitions.
• Perform spatial analysis of demographic data within these electoral regions.
• Integrate these boundaries into a larger UK-wide administrative geography dataset.
• Study changes in electoral region boundaries over time by comparing with other vintages.

Strengths

• Boundaries are temporally specific, representing the geography as of December 2017.
• Data is generalised to a 20-meter resolution, providing a consistent level of detail.
• Available in multiple geospatial formats including GeoPackage, GeoJSON, and ESRI File Geodatabase.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total geographic area covered are unknown, which may limit suitability assessment.
• Freshness should be verified; the underlying boundary data is from 2017, though metadata was updated in 2023.
