The dataset includes codes and names for each administrative level and was published by the Government Digital Service. It was last updated on the platform on 11 August 2025.
Use Cases
- Aggregating local statistics from parish to district level based on the hierarchical codes.
- Validating and standardizing geographic identifiers in other datasets using the official PAR21CD, WD21CD, and LAD21CD codes.
- Creating maps or visualizations of administrative boundaries in England and Wales using the named geographic entities.
Strengths
- Provides a snapshot of administrative boundaries for a specific date (31 December 2021), ensuring temporal consistency.
- Includes official government codes (e.g., PAR21CD, LAD21NM) for reliable joins with other statistical datasets.
- Field lengths are specified (e.g., PAR21NM up to 66 characters), which suggests structured data validation.
Limitations
