Output Areas
The 2001 Census Output Areas are designed specifically for statistical purposes. They are based on data from the 2001 Census and are built from postcode units. Output Areas are used not only for Census output but also as the basis of Super Output Areas which have been introduced as stable and consistently sized areas for Neighbourhood Statistics.
