Northern Ireland Electoral Ward Boundaries from 1993

Northern Ireland's electoral wards as defined in 1993, provided as a polygon dataset. The data originates from the Ordnance Survey Northern Ireland (OSNI) Largescale database and has been topologically cleansed to create a seamless layer. It is published by the Government Digital Service under an Open Government Licence.

Use Cases

• Mapping historical electoral boundaries based on the 1993 definition
• Conducting spatial analysis of demographic or political data aggregated to the 1993 ward level
• Creating base layers for historical or comparative cartography in Northern Ireland
• Performing topological operations on a cleansed polygon dataset

Strengths

• Data is topologically cleansed, suggesting it is suitable for spatial analysis without gaps or overlaps
• Derived from the authoritative OSNI Largescale database
• Available in multiple standard geospatial formats including GeoJSON and ESRI Shapefile

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; the dataset reflects a static 1993 snapshot
