1991 Scotland Census Localities: Built-Up Area Boundaries

603 locality boundaries in Scotland defined for the 1991 Census to represent built-up areas. The Scottish Government created these boundaries by classifying postcodes as urban or rural based on population density, grouping contiguous high-density postcodes with at least 500 residents. Local authorities were consulted to refine the final boundaries, resulting in 448 localities with 1,000 or more residents.

Use Cases

• Mapping urban and rural settlement patterns based on the described 1991 postcode classification.
• Analyzing population distribution for localities with 500 or more residents as defined in the methodology.
• Studying changes in Scotland's built-up environment following the 1975 local government reorganization mentioned in the description.
• Validating or refining administrative boundaries using the local authority consultation process described.

Strengths

• Defines 603 distinct localities, providing granular geographic units for analysis.
• Includes 448 localities with populations of 1,000 or more, covering significant settlements.
• Methodology involved consultation with local authorities, potentially improving boundary accuracy.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from 1991 and may not reflect current settlement patterns or boundaries.
• Row count is unknown, which may limit suitability assessment for specific analytical tasks.
