The NSPL relates both current and terminated postcodes to a range of current statutory geographies via ‘best-fit’ allocation from the 2021 Census Output Areas (national parks and Workplace Zones are exempt from ‘best-fit’ and use ‘exact-fit’ allocations) for England and Wales. Scotland and Northern Ireland has the 2011 Census Output AreasIt supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, who provide geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations. The NSPL is issued quarterly.

The UK censuses took place on 27 March 2011. They were run by the Northern Ireland Statistics & Research Agency (NISRA), National Records of Scotland (NRS), and the Office for National Statistics (ONS) for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.

Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics and underpin funding allocation to provide public services. This is the home for all UK census data.

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. Migration data at Local Authority District, Ward, and Output Area level.
• Special Student Statistics: Migration data at Local Authority District, Ward, and Output Area level.
• Census commuting datasets: Special Workplace Statistics: Commuting data at Local Authority District, Middle-layer Super Output Area, Intermediate Zone (for Scotland), Workplace Zone (for England and Wales), and Output Area level.
• Census second residence datasets: Special Residence Statistics. Commuting data at Local Authority District, Ward, and Output Area level.

Explicit registration is not required for the 2011 Census products that have been released under the Open Government Licence. However, outputs from the 2011 Census classified as 'safeguarded' require users to agree on additional terms and conditions. Access to these datasets is only permitted via Federated Access.

The Flow Data website provides two basic routes to the data.

• WICID is the main route to the flow data. It provides a flexible service to download extracts of data in a variety of forms;
• the Downloads page allows users to download the original tables as released by ONS.

The UK censuses took place on 21st April 1991. They were run by the Census Office for Northern Ireland, General Register Office for Scotland, and the Office of Population and Surveys for both England and Wales. The UK comprises the countries of England, Wales, Scotland and Northern Ireland.

Statistics from the UK censuses help paint a picture of the nation and how we live. They provide a detailed snapshot of the population and its characteristics, and underpin funding allocation to provide public services.

The aggregate data produced as outputs from censuses in Great Britain 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 or households resident in specific geographical areas possessing particular characteristics.

The topics covered by the 1991 Census were virtually the same as those in the 1981 Census. However, new questions were introduced on limiting long-term illness, ethnic group, central heating and term-time address of students. Also a question on weekly hours worked was re-introduced.

The 100% Sample files include information about total population; population in private households and communal establishments; sex; age; marital status; country of birth; ethnicity; migration; employment status; economic activity; household composition; dependent children; dependant adults; long-term illness; household car availability; housing; housing tenure; housing amenities; central heating; linguistic ability (Welsh/Gaelic in Wales and Scotland respectively).

The 10% Sample files contain information about socio-economic composition; employment status; occupations; industry of occupation; hours of work; commuting; qualifications, family type; household composition; age; sex; marital status; ethnicity; housing tenure; social class.

Local Base Statistics (LBS)
The 1991 Census Local Base Statistics (LBS) have around 20,000 statistical counts (cells) contained in 99 tables and cover the complete range of topics in the 1991 Census. They form the basis of the tables to be reproduced for each county (in England and Wales) and region (in Scotland) and for each local authority district. The LBS are available down to ward level in England and Wales and postcode sector level in Scotland.

Small Area Statistics (SAS)
The 1991 Census Small Area Statistics (SAS) tables are an abbreviated version of the Local Base Statistics. They comprise around 10,000 counts for each area and are available as an abstract of some 86 tables for geographic areas down to Enumeration District level in England and Wales and Output Area level in Scotland.

Data can be accessed through CKAN (to bulk download data).

This dataset provides Census 2021 estimates for Occupation in Northern Ireland. The estimates are as at census day, 21 March 2021.

The census collected information on the usually resident population of Northern Ireland on census day (21 March 2021). Initial contact letters or questionnaire packs were delivered to every household and communal establishment, and residents were asked to complete online or return the questionnaire with information as correct on census day. Special arrangements were made to enumerate special groups such as students, members of the Travellers Community, HM Forces personnel etc. The Census Coverage Survey (an independent doorstep survey) followed between 12 May and 29 June 2021 and was used to adjust the census counts for under-enumeration.

The focus of the study was the inter-relationship between women's work, particularly that of married women working outside the home, and low levels of fertility in mid-nineteenth century textile communities. Although the data were collected for the purpose of studying fertility patterns, they may be of interest to a wider range of specialists, including social and economic historians, sociologists, geographers and genealogists.
