2001 Census: Geography Classifications

Results from the 2001 Census are available for a wide range of census areas, from the smallest area (Output Area (OA)) to the largest area (Scotland). The main census areas for which results are made available were decided in consultation with users.

The main building bricks for census areas are OA's and all higher geographies are built from these. The PDF document (7 KB) 2001 Census Areas shows how the different areas nest into higher areas, all derived from OA's. Any area for which census output is produced is the aggregation of OA's that approximate best to the area. OA's will aggregate exactly to a council area but not necessarily to any other type of area.

Further details are contained in the PDF document (34 KB) 2001 Census Geography Classifications.
