OSNI Open Data: Northern Ireland District Electoral Area Boundaries (1993)

Northern Ireland's District Electoral Area (DEA) boundaries as they were in 1993, published as open data by the Land & Property Services (LPS). This dataset provides a historical snapshot of the administrative and political geography used for local elections. It is available in multiple geospatial formats for use in desktop and web mapping applications.

Use Cases

• Historical mapping of electoral districts based on the 1993 boundary definitions.
• Analyzing changes in political representation by comparing these 1993 boundaries to current ones.
• Spatial analysis of demographic or socio-economic data aggregated to the 1993 DEA level.

Strengths

• Published as official open data by a government agency (Land & Property Services/LPS).
• Available in multiple standard geospatial formats (e.g., ESRI Shapefile, GeoJSON, KML).
• Represents a specific, documented historical snapshot (1993 boundaries).

Limitations

• Key metadata such as row count, column names, and file size is unavailable across all sources.
• The dataset is a static snapshot from 1993 and does not reflect subsequent boundary changes.
• Platform update dates conflict (some show 2026, others are null), casting doubt on maintenance.
