A nationwidecensus, known asCensus 2001, was conducted in the United Kingdom on Sunday, 29 April 2001. This was the 20thUK census and recorded a resident population of 58,789,194.
The 2001 UK census was organised by theOffice for National Statistics (ONS) inEngland and Wales, theGeneral Register Office for Scotland (GROS) and theNorthern Ireland Statistics and Research Agency (NISRA). Detailed results by region, council area, ward andoutput area are available from their respective websites.
Similar to previous UK censuses, the 2001 census was organised by the three statistical agencies, ONS, GROS, and NISRA, and coordinated at the national level by the Office for National Statistics. TheOrders in Council to conduct the census, specifying the people and information to be included in the census, were made under the authority of theCensus Act 1920 in Great Britain, and theCensus Act (Northern Ireland) 1969 in Northern Ireland. In England and Wales these regulations were made by the Census Order 2000 (SI 744/2000), in Scotland by the Census (Scotland) Order 2000 (SSI 68/2000), and in Northern Ireland by the Census Order (Northern Ireland) 2000 (SRNI 168/2000).[1]
The census was administered through self-completion forms, in most cases delivered byenumerators to households and communal establishments in the three weeks before census night on 29 April. For the first time return by post was used as the main collection method, with enumerators following up in person where the forms were not returned. The postal response rate was 88% in England and Wales,[2] 91% in Scotland,[3] and 92% in Northern Ireland.[4] A total of 81,000 field staff were employed across the UK (70,000 in England and Wales, 8,000 in Scotland and 3,000 in Northern Ireland).[1] The census was conducted at the height of thefoot-and-mouth crisis, which led to extra precautions being adopted by the field staff, and suggestions that the census may have to be postponed.[5] However, it was reported that the disease outbreak did not affect the effectiveness of the collection process.[6][7]
The census was estimated to cost £259m over its 13-year cycle from the start of planning in 1993 to the delivery of final results in 2006.[8][9] Printing of the 30 million census forms was subcontracted to Polestar Group, and processing of the returned census forms was subcontracted toLockheed Martin in a contract worth £54m.[10] The forms were initially scanned into digital format, then read withOMR andOCR, with manual entry where the automatic process could not read the forms. The forms were thenpulped and recycled, and the digital copies printed ontomicrofilm for storage and release after 100 years. Once the data were returned to the statistics agencies it underwent further processing to ensure consistency and to impute missing values.
The overall response rate for the census, that is the proportion of the population who were included on a census form, was estimated to be 94% in England and Wales,[11] 96.1% in Scotland[12] and 95.2% in Northern Ireland.[13] This was due to a number of factors: households with no response, households excluding residents from their returns, and addresses not included in the enumeration. In Manchester for example 25,000 people from 14,000 addresses were not enumerated because the address database was two years out of date.[14][15] The Local Authority with the lowest response wasKensington and Chelsea with 64%.Hackney had the next lowest response at 72%. Out of all local authorities, the ten lowest response rates were all in London.[11] The results still represent 100 per cent of the population, however, because some individuals not completing their forms were instead identified by census enumerators, and through the use of cross-matching with a follow-up survey.[16]
The results from the 2001 census were produced using a methodology known as the One Number Census.[17] This was an attempt to adjust the census counts and impute answers to allow for estimated under-enumeration measured by the Census Coverage Survey (sample size 320,000 households), resulting in a single set ofpopulation estimates.[18]
Although the 1851 census had included a question about religion on a separate response sheet, whose completion was not compulsory, the 2001 census was the first in Great Britain to ask about thereligion of respondents on the main census form.[citation needed] An amendment to the 1920 Census Act (theCensus (Amendment) Act 2000) was passed by Parliament to allow the question to be asked, and to allow the response to this question to be optional.[19][20] The inclusion of the question enabled theJedi census phenomenon to take place in the United Kingdom. In England and Wales 390,127 people stated their religion asJedi, as did 14,052 people in Scotland.[21]The percentages of religious affiliations were:
15% declared themselves ofno religion (including Jedi at 0.7%, more than those who declared themselves as Sikh, Jewish or Buddhist) and 8% did not respond to the question.[22]
The census ethnic groups includedWhite (White British,White Irish,Other White),Mixed (White and Black Caribbean,White and Black African,White and Asian,Other Mixed),Asian or Asian British (Indian,Pakistani,Bangladeshi,Other Asian),Black or Black British (Black Caribbean,African,Other Black) andChineseor Other Ethnic Group.

Since the UK census relies on self-completion,[23] the composition of the other ethnic group category is not fixed. Analysis by theOffice for National Statistics of the 220,000 people in England andWales who ticked the other ethnic group box in the 2001 census reveals that 53 per cent were born in theFar East, 10 per cent in the UK, 10 per cent in theMiddle East, and 7 per cent inAfrica.[24] People could write in an ethnic group under the 'other' heading. 26 per cent did not specify an ethnicity, but of the remainder 23 per cent wroteFilipino, 21 per centJapanese, 11 per centVietnamese, 11 per centArab, 6 per cent Middle Eastern and 4 per centNorth African.[24]
Controversy surrounding the classification of ethnic groups began as early as 2000, when it was revealed that respondents inScotland andNorthern Ireland would be able to check a box describing themselves as Scottish or Irish, an option not available for English respondents.[25] With an absence of an English tick-box, the only other tickbox available was "white-British", "Irish", or "other". However, if 'English' was written in under the "any other white background" it was not clear whether it would be counted as an ethnic group in same the way as the Welsh.[25] Following criticism, English was included as a tick-box option in the 2011 census.[26][27]
It is sometimes claimed that the 2001 census revealed that two-thirds of the population ofWales described themselves as ofWelsh nationality.[6] In fact, the 2001 census did not collect any information on nationality. Controversy surrounding the classification of ethnic group began as early as 2000, when it was revealed that respondents inScotland andNorthern Ireland would be able to check a box describing themselves as Scottish or Irish, an option not available for Welsh respondents.[28][29] Prior to the census,Plaid Cymru backed a petition calling for the inclusion of a Welsh tickbox and for theNational Assembly for Wales to have primary law-making powers and its own National Statistics Office.[28] With an absence of a Welsh tickbox, the only other tickbox available was "white-British", "Irish", or "other".[6][28]
For the first time in a UK census, those wishing to describe their ethnicity asCornish were given their own code number (06) on the 2001 UK census form, alongside those for people wishing to describe themselves as English,Welsh, Irish or Scottish. About 34,000 people in Cornwall and 3,500 people in the rest of the UK wrote on their census forms in 2001 that they considered their ethnic group to be Cornish.[30] This represented nearly 7% of the population of Cornwall. Various Cornish organisations were campaigning for the inclusion of the Cornish tick box on the next census in 2011.[31]
