- Geodemographic
- Areas created by grouping together smaller areas that have 
similar characteristics - the components of a grouped area are not necessarily contiguous.

## Sub Uk Geography

- Attaching geography by reference to postcode
•
ONS Postcode Directory (ONSPD) - assigns individual postcodes separately to each 
higher level geography 
•
National Statistics Postcode Lookup (NSPL) - assigns individual postcodes to Output Areas (OAs), and then using its assigned OA to lookup its higher level geography.
A key principle of the Geography Policy for National Statistics is that statistics for higher level geographies should be built from "small area stable statistical building bricks". These are Output Areas, or Super Output Areas if not available at OA.  The purpose of the policy is that national statistics are geographically consistent and comparable.
