Small area population estimates project: data quality of administrative datasets

Area of Science:

• Demography
• Population Statistics
• Geographic Information Systems

Background:

• Accurate small area population estimates are crucial for policy and resource allocation.
• Existing methods may not provide nationally consistent estimates for England and Wales.
• The Office for National Statistics (ONS) initiated a project to address this data gap.

Purpose of the Study:

• To investigate the feasibility of producing postcensal small area population estimates.
• To identify and evaluate administrative datasets suitable for this purpose.
• To establish a nationally consistent methodology for England and Wales.

Main Methods:

• Conducted research to identify potential administrative datasets.
• Evaluated various administrative data sources based on 2001 data.
• Short-listed the most suitable datasets for further consideration.

Main Results:

• A range of administrative datasets were assessed for their utility in population estimation.
• The characteristics of the most promising data sources were summarized.
• Specific datasets were identified as suitable for further methodological development.

Conclusions:

• The evaluation identified several administrative datasets as viable for producing small area population estimates.
• These shortlisted datasets form the basis for future methodological research.
• The project is a step towards achieving nationally consistent population estimates.
