OA to LAD to LSOA to MSOA to LEP (non overlapping parts) (December 2014) Lookup in England

Office for National Statistics provides a lookup table for non-overlapping parts of different administrative geographies in England. The dataset maps relationships between Output Areas (OA), Local Authority Districts (LAD), Lower Layer Super Output Areas (LSOA), Middle Layer Super Output Areas (MSOA), and Local Enterprise Partnerships (LEP) as of December 2014. It is published under the OGL-UK-3.0 license and was last updated on the platform in July 2026.

Use Cases

• Aggregating socio-economic data from small areas (LSOA) to larger districts (LAD) based on the lookup relationships.
• Joining datasets that use different geographic coding systems (e.g., OA to MSOA) for unified analysis.
• Mapping data to Local Enterprise Partnership (LEP) regions for regional economic analysis.
• Validating the geographic consistency of multi-source datasets for England.

Strengths

• Published by the authoritative Office for National Statistics, the UK's national statistical institute.
• Has a clear reference date (December 2014) for the geographic boundaries.
• License is explicitly stated as OGL-UK-3.0, facilitating reuse.

Limitations

• Description metadata is limited; actual data quality and column semantics require manual inspection after download.
• Row count is unknown, which may limit suitability assessment for large-scale joins.
• The data reflects a specific snapshot from 2014; boundary changes after this date are not included.
