Code History Database: UK Statistical Geography Codes and Hierarchies as of February 2017

GSS nine-character codes for UK statistical geographies from 1 January 2009, providing details of codes, relationships, and hierarchies. The database, maintained by the Government Digital Service, includes updated geographies such as Sustainability and Transformation Plan footprints and a new LSOA to CCG to STP lookup from February 2017. It is designed for use in conjunction with the Register of Geographic Codes.

Use Cases

• Track changes to UK administrative and statistical geography codes based on the code history functionality.
• Analyze hierarchical relationships between geographic entities like LSOAs, CCGs, and STPs based on the described relationships.
• Maintain consistency in statistical exchanges by applying the GSS Coding and Naming policy implemented from 1 January 2011.

Strengths

• Provides a structured history of geographic codes from 1 January 2009.
• Includes specific updates for February 2017, such as new STP codes E54000045 to E54000048.
• Codes follow a defined alphanumeric structure with a three-character entity type and six-character instance identifier.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from February 2017; freshness should be verified for current applications.
