Notes
This field contains 2011 Local Authority Districts (for England and Wales) and Council Areas (for Scotland) corresponding to each participant's home address at assessment.
This field will only be released following special approval.
For most purposes, these areas will provide sufficient information on location of residence at assessment. If a higher level of granularity is required, codes are also available for Lower layer Super Output Areas (England and Wales) / Data Zones (Scotland), in Field 20274, and Middle layer Super Output Areas (England and Wales) / Intermediate Zones (Scotland), in Field 20275.
