Geographic products include digital Output Area boundaries for use in geographical information systems and look-up files which describe the postcodes that form Output Area and indicate which Output Areas form a range of higher administrative and other geographies. These look-up files can be used to aggregate results for Output Areas to higher areas or to link non-census data coded to postcodes to the ‘denominators’ provided by Census statistics.
The products are generally supplied without charge from the Geography Portal on the ONS website.
