Census 2011 - Specialist Products
As with previous Censuses, NISRA is committed to producing Microdata Samples of Anonymised Records (SARs) from the 2011 Census. This work is being advanced collaboratively with the other UK Census Offices and in conjunction with key users.
The products that are currently envisaged are:
Teaching File (1% Sample of Individual Records)
This file is considerably less detailed than the file made available under end-user licence in 2001. It constitutes a 'taster' file, of particular use in teaching.
The Microdata Teaching File (CSV 328 KB) is available to download from the NINIS website from 23 January 2014.
More information on the teaching file can be found in Microdata Teaching File - Product Overview (PDF 113 KB) document.
An anonymised sample of individuals and an anonymised sample of households - the maximum size of these samples will be 10%. These samples will be non-overlapping and will be the most detailed available. Accordingly, they will only be available in the Secure Setting of the Virtual Microdata Laboratory (VML) managed by the Office for National Statistics (ONS). It is envisaged that users in Northern Ireland will be able to access these files from within the secure setting in NISRA Headquarters using the secure link to the VML.
An anonymised sample of individuals, which will be available to approved researchers via specific end-user licence arrangements - the maximum size of the sample will be 5%. This sample will be drawn from, and hence overlap with, the proposed secure sample (maximum of 10%) of individuals mentioned above. The level of detail included for each record in the sample will however be adjusted (i.e. it will be less detailed) to reflect the associated access arrangements and the need to preserve the confidentiality of the information, which is paramount.
Further information on microdata can be accessed on the UK Data Service website.
