Population Age Statistics from the 2001 Census of England and Wales

England and Wales census data from 2001 provides median and mean age statistics for the population. The data is published by the Office for National Statistics via Neighbourhood Statistics and covers multiple geographic levels from Output Areas to the national level. Age was derived from date of birth, with imputation applied for invalid entries implying an age over 110.

Use Cases

• Analyze population aging trends based on median and mean age statistics.
• Model demographic distributions for local government planning based on census geography.
• Compare age structures across different administrative regions like Local Authority Districts and Wards.

Strengths

• Data originates from a national census, a comprehensive population survey.
• Covers multiple geographic granularities from Output Area to National level.
• Age data underwent a specific imputation process for values over 110.

Limitations

• Data is from a single year (2001), limiting temporal analysis.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
