Office for National Statistics provides a lookup file mapping UK local authority districts (LAD) to Local Administrative Units (LAU1) and NUTS (Nomenclature of Territorial Units for Statistics) geography levels 1, 2, and 3 as of 1 January 2018. The dataset includes columns for codes and names at each geographic level. It is available in CSV, GeoJSON, and ESRI REST formats.
Use Cases
- Aggregating local statistics to NUTS regions based on the LAD16CD to NUTS code mappings
- Joining datasets using LAU1 codes based on the LAU118CD column
- Translating between different UK geographic hierarchies based on the lookup relationships described
- Validating or standardizing geographic identifiers in UK datasets
Strengths
- Lookup relationships are explicitly defined for a specific snapshot date (1 January 2018)
- Includes both code and name columns for five distinct geographic levels (LAD, LAU1, NUTS3, NUTS2, NUTS1)
- Available in multiple standard formats including CSV and GeoJSON
Limitations
- Description metadata is limited; actual data quality requires manual inspection after download
- Row count is unknown, which may limit suitability assessment
- Data is a static snapshot from January 2018; freshness should be verified for current analyses
