National Assembly for Wales Constituency Boundaries as of December 2016

Office for National Statistics provides digital vector boundaries for National Assembly for Wales Constituencies, as at 31 December 2016. The dataset contains four boundary versions: full resolution (extent of the realm and clipped to coastline), generalised (20m), and super generalised (200m). It includes Ordnance Survey and ONS Intellectual Property Rights.

Use Cases

• Mapping electoral constituencies for Wales based on the provided full-resolution boundaries.
• Conducting spatial analysis of Welsh political representation using coastline-clipped boundaries.
• Creating simplified visualizations or web maps using the generalised (20m) or super generalised (200m) boundary files.
• Integrating with other UK geospatial datasets for regional planning or demographic studies.

Strengths

• Provides four distinct boundary versions for different use cases, from full resolution to super generalised.
• Specific snapshot date of 31 December 2016 ensures temporal consistency for analysis.
• File sizes are explicitly listed, ranging from 87 KB to 5 MB, indicating manageable download sizes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
