Is it possible to merge in data on geographical identifiers eg Census information?

A range of geographical identifiers are available for Understanding Society which allow researchers to merge external data at different geographical levels to individuals’ responses. Examples of geographical identifiers at higher level include country and Government Office Region; at medium level Local Authority Districts and Travel to Work Areas; at lower level Lower Layer Super Output Areas.
The availability of geographical identifiers depends on their spatial scale and on the location of the site of access. Indicators at larger scale such as UK Region of residence are distributed with the general release of Understanding Society . Geographical identifiers at medium level are available to UK and non-UK users applying for a Special License, whereas lower-level identifiers are only available to UK users holding a Special License. Finally, the grid reference of postcodes is available through Secure Data Access. For more information on the access conditions:
