UK Geographic Hierarchy Lookup for Output Areas to NUTS Regions (December 2011)

Office for National Statistics provides a lookup table linking small geographic units to larger administrative regions. This dataset maps Output Areas in England and Wales to their corresponding LAU2, LAU1, NUTS3, NUTS2, and NUTS1 statistical geographies as defined in December 2011. It is available under the OGL-UK-3.0 license and was last updated on the platform in July 2026.

Use Cases

• Aggregate small-area statistics to higher-level administrative regions based on the hierarchical lookup codes.
• Join datasets using different geographic classification systems based on the provided mapping.
• Analyze regional patterns in England and Wales by assigning data points to consistent NUTS regions.
• Validate the geographic consistency of other datasets by cross-referencing the official 2011 boundaries.

Strengths

• Official source from the UK's Office for National Statistics, an authoritative producer of geographic standards.
• Provides a clear hierarchical mapping between five levels of statistical geography.
• Specific reference date (December 2011) for the geographic definitions used.

Limitations
