The main population base for published statistical tables from the 2011 Census in Northern Ireland is the usual resident population base as at Census day, 27 March 2011. By way of background, for 2011 Census purposes a usual resident of the United Kingdom (UK) is anyone who, on Census day, was in the UK and had stayed or intended to stay in the UK for a period of 12 months or more, or had a permanent UK address and was outside the UK and had intended to be outside the UK for less than 12 months. Against this background, the 2011 Census Microdata Sample of Anonymised Records (SARs) Teaching File comprises a sample of 19,862 records (approximately 1 per cent) relating to people who were usually resident in Northern Ireland at the time of the 2011 Census. For each individual, information is available for seventeen separate characteristics (for example, sex, age, marital status) to varying degrees of detail. Both the size of the sample and the content of the records in the file have been harmonised, wherever possible, with the equivalent SARs teaching file that the Office for National Statistics simultaneously released for England and Wales. Purpose The primary purpose of the teaching file, which comprises unit-record level data as opposed to statistical aggregates, is as an educational tool aimed at: encouraging wider use of Census data by facilitating another way of examining Census data, for example through the building of statistical models, over and above that already available through the raft of standard tabular output released to date; providing a broad insight into the sort of detail that is generally included in a SARs product, along with data formats and any associated metadata. This will enable users (arguably those less experienced at using SARs products) to ‘play’ with the data and increase their knowledge and skills in readiness for accessing the more detailed SARs products that are planned and will be available in, for example, a safe setting; and assisting with the teaching of statistics and geography at GCSE and higher levels.

The aggregate data produced as outputs from censuses in the United Kingdom provide information on a wide range of demographic and socio-economic characteristics. They are predominantly a collection of aggregated, or summary counts of the numbers of people, families or households resident in specific geographical areas possessing particular characteristics drawn from the themes of population, people and places, families, ethnicity and religion, health, work, and housing.

Aggregate data for Census 2011 cover the full range of geographies employed within the census, from the smallest (output areas with an average of 150 persons in England and Wales) to the nation as a whole.

Census flow data involve flows of individuals in the UK between origins and destinations. These flows are either the residential migrations of individuals from one place of usual residence to another, or of commuters making journeys from home to workplace or place of study. These data are derived from the questions on the census form relating to usual place of residence one year ago, and the place of work for the respondent's main job. Flow data are currently available at a range of different spatial scales ranging from Output Areas to Local Authority Districts. Main Topics: The Census Support: Flow Data website facilitates access to the interaction data for members of UK higher and further education institutions. Access is provided through the Web-based Interface to Census Interaction Data (WICID). The 2011 sets currently held include:Census migration datasets: Special Migration Statistics.

Abstract copyright UK Data Service and data collection copyright owner. The 1981 Census Microdata Teaching Dataset for Great Britain: 1% Sample: Open Access dataset was created from existing digital records from the 1981 Census. It can be used as a 'taster' file for 1981 Census data and is freely available for anyone to download under an Open Government Licence. The file was created under a project known as Enhancing and Enriching Historic Census Microdata Samples (EEHCM), which was funded by the Economic and Social Research Council with input from the Office for National Statistics and National Records of Scotland. The project ran from 2012-2014 and was led from the UK Data Archive, University of Essex, in collaboration with the Cathie Marsh Institute for Social Research (CMIST) at the University of Manchester and the Census Offices. In addition to the 1981 data, the team worked on files from the 1961 Census and 1971 Census. The original 1981 records preceded current data archival standards and were created before microdata sets for secondary use were anticipated. A process of data recovery and quality checking was necessary to maximise their utility for current researchers, though some imperfections remain (see the User Guide for details). Three other 1981 Census datasets have been created: SN 8241 - 1981 Census Microdata Individual File for Great Britain: 5% Sample, which contains information on individuals in larger local authorities;SN 8242 - 1981 Census Microdata Household File for Great Britain: 0.95% Sample, which links household members together to allow individuals to be understood within their household context. SNs 8241 and 8242 are both available to registered UK Data Service users based in the United Kingdom (see Access section for non-UK access restrictions); andSN 8248 - 1981 Census Microdata for Great Britain: 9% Sample: Secure Access, which comprises a larger population sample and so contains sufficient information to constitute personal data, meaning that it is only available to Accredited Researchers, under restrictive Secure Access conditions. Main Topics: Topics covered include demographics, for example age, gender, family, marital status, housing tenure, employment and qualifications, and housing tenure. 1% sample of the 1981 Census Compilation or synthesis of existing material

This dataset provides 2011 Census estimates of the workplace population in England and Wales by residence type (household or communal resident), by sex and by age. The estimates are as at census day, 27 March 2011.

Statistics about the number and demographic characteristics of people are used to monitor differences and track how these proportions change over time.

Statistical Disclosure Control

In order to protect against disclosure of personal information from the 2011 Census, there has been swapping of records in the Census database between different geographic areas, and so some counts will be affected. In the main, the greatest effects will be at the lowest geographies, since the record swapping is targeted towards those households with unusual characteristics in small areas.

More details on the ONS Census disclosure control strategy may be found on the http://www.ons.gov.uk/ons/guide-method/census/2011/census-data/2011-census-prospectus/new-developments-for-2011-census-results/statistical-disclosure-control/index.html[Statistical Disclosure Control] page on the ONS web site.
