Boundaries and other geography products

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 adminsitrative and other geographies. Tese 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, although material costs may be recovered. The following products are available:
