These lookup files provide a best-fit of Output Areas to other common geographies, and allow Census results such as Census Area Statistics for Output Areas to be aggregated to higher level areas such as Parliamentary Constituencies, urban areas, or postcode sectors. Information is also included for local authority, health and electoral geographies, as are details of sub-threshold areas which have been combined for the purposes of Census results.

A full technical description of the product content is available HERE, and a summary of the higher areas included is available HERE.
