It will include the travel-to-work and migration patterns of individuals, cross-tabulated by variables of interest (for example occupation). New products for the 2011 Census will also provide the migration patterns of those living at a student address one year ago and provide information on individuals with second residences.

Statistics available from this release include main language, method of travel to work and economic activity of students. Interactive data visualisations are also available to aid interpretation and users can enter postcodes into the interactive maps to focus on specific areas.

The statistics in this release are a new presentation of the data released as part of the Key Statistics and Quick Statistics for output areas in England and Wales that were published 30 January 2013. They provide new best fit aggregations of these statistics for health administration areas and postcode sectors in England and Wales, and also for National Assembly for Wales constituencies and Assembly for Wales electoral regions. The estimates are best-fitted from output areas in line with the Geography Policy for National Statistics.

The Key and Quick Statistics tables for the United Kingdom bring together data from the 2011 Censuses conducted in England and Wales, in Scotland, and in Northern Ireland, to provide UK harmonised data for areas throughout the United Kingdom. These UK tables were released by ONS in 2014 as downloadable files, and have now been added to the wide range of Census data available through nomis

The Office for National Statistics (ONS) has shared plans to produce four microdata files from the 2011 Census. An updated ONS output prospectus which includes timescales for census microdata is forthcoming. The first edition of these files will be limited to England and Wales, but it is hoped that a second edition will be UK wide. This link provides details of all the proposed files as well as references to the consultation on Microdata.

The first results from the 2011 Census were made available on Monday 16th July. See the link below for access to the household and population estimates and supporting information.

The Office for National Statistics has launched a consultation on the final geography policy for the 2011 Census outputs. The consultation will run until the 29th April and invites users to comment on the policy, the proposed set of geographic products and the outcome of the 2010 Census Output Geography consultation.

This report is on the inquiry by House of Commons Public Administration Select Committee (PASC) into the future of the census. It follows the publication by ONS of the recommendations of the National Statistician after a national consultation. The Inquiry agrees that the decennial census should be kept.
Witnesses emphasised, among other things, the great financial benefits to business provided by census data and these have been quantified. The Committee recommends that the ONS now scope and set out a more ambitious vision for the creative and full use of administrative data to provide rich and valuable population statistics, which could potentially be more accurate and up-to-date than the census, and cover new topics. It also recommends that the Government now embark upon a public information campaign to communicate the benefits of increased data sharing for statistical purposes, and the safeguards which will be in place to protect people’s personal information and privacy. The report includes formal minutes of the proceedings.

This gives the letter from The Rt Hon Francis Maude MP, Minister for the Cabinet Office, to Bernard Jenkin MP, Chair of PASC, dated 18 July 2014. It states that the Government welcomes the Committee's report and responds in detail to each of the report’s recommendations.

The Public Administration Select Committee reported to the House on Too soon to scrap the Census in its Fifteenth Report of Session 2013-14, published on 17 April 2014. The Government Response was received on 18 July 2014 and is published in this report as Appendix 1. The UK Statistics Authority's Response was received on 21 July 2014 and is published in this Report as Appendix 2.

A joint project has been set up between ONS and University College London to develop a new UK Output Area Classification, for which they are seeking your views and thoughts. The new Output Area Classification is planned to be created using 2011 Census data, when available, and is relevant to anyone interested in social area classifications, encompassing geodemographics and neighbourhood classifications.

A user engagement exercise began on 17 February 2012 and runs until 30 March 2012. For further information, and details on how to respond to this user engagement exercise, please see the ONS webpage for User Engagement on a new United Kingdom Output Area Classification:
