Background
History
The Registrar General John Rickman conducted the first census of Great Britain's population, and was responsible for the ten-yearly reports published between 1801 and 1831. During the first 100 years of census-taking the population of England and Wales grew more than threefold, to around 32 million, and that of Scotland, where a separate census has been carried out since 1861, to about 4.5 million. From 1911 onwards rapid social change, scientific breakthroughs, and major world events affected the structure of the population. A fire that destroyed census records in 1931, and the declaration of war in 1939, made the 1951 census hugely significant in recording 30 years of change over one of the most turbulent periods in British history. The 1971 census was run by the newly created Office of Population Censuses and Surveys (OPCS), a body formed by the merger of the General Register Office and Government Social Survey. In 1996 the Office for National Statistics (ONS) was formed by merging the Central Statistical Office (CSO), OPCS and the statistics division of the Department of Employment; the first census it ran was in 2001. In 2008 the UK Statistics Authority was established as an independent body.Purpose
A population census is a key instrument for assessing the needs of local communities. When related to other data sources such as housing or agricultural censuses, or sample surveys, the data becomes even more useful. Most countries of the world take censuses: the United Nations recommends that countries take a census at least once every ten years. Twenty-one out of 40 countries in Europe are engaged in the 2010–2011 census round The design for the 2011 census reflected changes in society since 2001 and asked questions to help paint a detailed demographic picture of England and Wales, as it stood on census day, 27 March 2011. Data collected by the census is used to provide statistical outputs which central government uses to plan and allocate local authority services funding, and which local authorities themselves use to identify and meet the needs of their local communities. Other organisations that use census data include healthcare organisations, community groups, researchers and businesses. The questionnaires, including people's personal information, are kept confidential for 100 years before being released to the public, providing an important source of information for historical, demographic and genealogy research.2011 Census for England and Wales
Operation
The 2011 census for England and Wales included around 25 million households. Questionnaires were posted out to all households, using a national address register compiled by the Office for National Statistics (ONS) with the help of local authorities through comparisons of the National Land and Property Gazetteer (NLPG) and the Royal Mail and Ordnance Survey national address products. People could complete and submit their questionnaire online, or fill it in on paper and post it back in a pre-addressed envelope. Guidance was provided online and through the census helpline. Completed questionnaires were electronically tracked and field staff followed up with households that did not return a questionnaire. Special arrangements were made to count people living in communal establishments such as; boarding schools, prisons, military bases, hospitals, care homes, student halls of residence, hotels, royal apartments and embassies, as well as for particular communities; rough sleepers, travellers and those living on waterways. In these cases field staff delivered and collected questionnaires and, where needed, provided advice or assistance in completing the questionnaire. There was a legal requirement to complete the 2011 census questionnaire, under the terms of theProduction
Lockheed Martin UK, the UK arm of US-basedCosts and value for money
The total cost of the 2011 Census in England and Wales over the period from 2004/05 to 2015/16 is estimated to be £482 million.http://www.parliament.uk/briefing-papers/SN05230.pdf This is more than twice the £210m spent on the 2001 census. This breaks down to a cost of 87 pence per person, per year (over the life of the census – ten years). “The cost equates to about 87p a year per person, demonstrating excellent value for money. The per capita costs in the UK are less than for many other European countries that carry out similar censuses. In summary, this census will meet crucial requirements for statistical information that Government and others cannot do without.” Minister of State, Cabinet Office ( Angela E. Smith). Both the main UK political parties had expressed concerns about the rising costs and value of a ten-yearly census, and on coming into office the UK coalition government had gone as far as suggesting that the 2011 census might be the last of its kind. In July 2010 the UK government asked ONS to explore other methods of measuring the population. In 2011 the three national statistics bodies, ONS, GROS and NISRA set up a co-ordinated research project known asChanges from 2001 census
The general style of the questionnaire was similar to that of the 2001 census. A rehearsal questionnaire was released in 2009. Several new identity and status options were included for the first time. Other changes for 2011 included: * An option to complete the form online. * The 2011 census questionnaire included 56 questions in total. * It asked immigrants their date of arrival and how long they intended to stay in the UK.Turner, Lauren (11 December 2008)Advertising
Advertising promoted the notion of how the UK 2011 census would help to shape Britain's future in areas such as healthcare and education. TV adverts, for example, depictedControversy
A question about the number of bedrooms a household has, as well as the names, gender and birth dates of any overnight guests was criticised as "bedroom snooping" by the Conservative Party in opposition. In a written answer in response to a question on population and the traditional enumeration methodology of the 2011 Census, Cabinet Office minister“The UK Statistics Authority is responsible for carrying out the census in England and Wales. The board of the authority has expressed the view that the 2011 census should be the last conduction on the traditional basis. Through the 'Beyond 2011 Beyond 2011, also known as The Beyond 2011 Programme, is a project initiated by the UK Statistics Authority to look at the alternatives to running a UK census in 2021. In 2008, the Treasury Select Committee had expressed concerns about the incre ...' project the authority has been considering alternative ways of obtaining information that has been traditionally gathered via a census.
The current advice from the ONS is clear. Census alternatives are not sufficiently developed to provide now the information required to meet essential UK and EU requirements. It is therefore important that the census goes ahead in England and Wales on 27 March 2011. ONS must do all it can to ensure it is a success."Although some 37,000 people recorded their identity as
2011 Census for Northern Ireland
The 2011 Census for Northern Ireland had 59 questions in total. 14 were about the household and its accommodation and 45 questions were for each individual member of the household to complete. The rehearsal was held on Sunday 11 October 2009 in two areas, Derriaghy and Moy & Benburb, covering approximately 5,000 households. The 2011 Census for Northern Ireland costing around £21.8 million over the six-year period 2008–2014. Over the ten-year cycle the cost is expected to be about £25 million.2011 Census for Scotland

The United Kingdom Statistics Authority is responsible for coordinating the release of census data by the devolved statistics authorities. It publishes UK-wide census data results via thPre-defined statistical tables
The format of all the pre-defined statistical tables is standardised as far as practical across the publishing authorities. Since the 2001 UK Census the naming conventions for the tables have been revised following research into the approaches adopted by other census publishing bodies around the world.Bulk data
The statistical authorities are also making available bulk data inCommissioned data
In addition to the standard releases and online bulk access the statistical authorities provide a commissioned data service whereby other data configurations can be purchased, under license, by customers and will subsequently made freely available to other users.See also
