Estimates of the number of usual residents, by sex, and the number of households with at least one usual resident, for each unit postcode at as census day, 27 March 2011.

Please note that Deprivation Ranks are released at Lower Super Output Area/Data Zone level and are not for each individual postcode.

The first resource below provides a list of all 2011 census frozen postcodes across the UK as well as the:

• Postcode's location in the UK (British National Grid, Irish Grid, Latitude-Longitude)
• Total persons recorded in that postcode
• Female or male breakdown of the postcode
• Number of occupied households in that postcode
• The Lower Super Output Area or Data Zone in which the postcode resides
• The Output Area or Small Area in which the postcode resides
• The Output Area's Classification:
  • OAC Supergroup (codes and names)
  • OAC Group (codes and names)
  • OAC Subgroups (codes and names)
• The Deprivation Ranks of the LSOA/DZ:
  • 2014 Welsh Index of Multiple Deprivation (WIMD) Rank for 2011 LSOAs
  • 2015 English Index of Multiple Deprivation (EIMD) Score, Rank and Decile for 2011 LSOAs
  • 2016 Scottish Index of Multiple Deprivation (SIMD) Rank for 2011 Data Zones
  • 2017 Northern Irish Multiple Deprivation Measures (NIMDM) Rank for SOAs
  • Townsend Deprivation Index score and quintile of LSOAs and Data Zones
  • Townsend Deprivation Index score and quintile of Output Areas and Small Areas

Suppressed postcodes in Northern Ireland

For confidentiality reasons, counts were suppressed for postcodes that had less than 10 usual residents and had only 1, 2 or 3 households in them.

The Registrar General took steps to ensure that the confidentiality of respondents was fully protected. Accordingly, all published results from the 2011 Census (including those relating to Postcodes) were subject to statistical processes to ensure that individuals could not be identified. For these postcodes, averages were taken at Postcode District level and released in a separate table, which can be found below.

Missing postcodes

These postcodes are based upon the sets of enumeration postcodes provided by the three UK census agencies. Enumeration postcodes are a subset of the complete set of live postcodes at the time of the 2011 Census. These are aggregated to create census output areas, which are themselves aggregated to create most other census geographies.

Only postcodes with at least one resident person are included. Many postcodes, such as those assigned to businesses, don't have any resident populations and so won't appear in the table.

Postcodes are quite volatile; new postcodes are created and old ones are terminated regularly. Existing/live postcodes can also change through the addition or removal of delivery points. The ONSPD records all live and terminated postcodes. Each postcode has a date of introduction and, if relevant, a date of termination. Things are complicated further because postcodes can be re-used, so a postcode can be terminated and then reappear with a new date of introduction, replacing/removing the record for the previous instance of the postcode. Postcodes that weren't current at the time of the census also won't appear in the table.

Workplace Zones (WZs) are a new output geography, initially produced using workplace data from the 2011 Census for England and Wales rather than the UK as a whole. They are designed to supplement the Output Area (OA) and Super Output Area (LSOA and MSOA) geographies that were introduced with the 2001 Census, and have been constructed from OAs, or sub-divisions of these called postcode-level building-blocks (PCBBs). While OAs are designed to contain consistent numbers of persons based on where they live, WZs are designed to contain consistent numbers of workers, based on where people work. Following publication of WZs for England and Wales, coverage has subsequently been extended to include Scotland and Northern Ireland using 2011 Census data to create a UK set of WZs produced by the Office for National Statistics (ONS) on behalf of National Records of Scotland (NRS) and the Northern Ireland Statistics and Research Agency (NISRA). WZs are designed to be a more suitable output geography for publishing workplace statistics.

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.

Postcode unit boundaries are created and maintained by National Records of Scotland (NRS) for every live small user postcode so that the entire land surface of Scotland is covered by postcode polygons. This is the set of postcode boundaries used for 2011 census outputs. The dataset contains 145,690 postcode polygons.

A lookup between 2011 Census enumeration postcodes for England and Wales, and the parishes / communities, wards and local authority districts as at 31 December 2011. Enumeration postcodes are a sub-Output Area (OA) geography used only for the publication of estimates of males, females and households in the 2011 Census. The enumeration postcodes are defined as only those valid unit postcodes that were recorded during the 2011 Census as containing usually resident population. Postcodes have been assigned using a ‘point-in-polygon’ methodology that plots each postcode's mean address (centroid) into the areas of each of the parishes / communities, wards and local authority districts (LAD). In England there is not a full coverage of parishes, so the 2011 Census enumeration postcodes that do not fall into a parish will have no parish allocation. There are also 23 parishes (0.2%) that do not contain any enumeration postcode centroids. This occurs where a parish contains population, but the centroid of the postcode falls outside the parish. In these instances it is not possible to allocate a postcode to the parish.

Workplace Zone (WZ) centroids are point features that represent the 'master postcodes' for WZs. The centroid, or 'master postcode' was selected using an algorithm which calculates the postcode centroid within a WZ which has grid references closest to the worker-weighted centre of the DZ. These centroids / 'master postcodes' can be used to link WZs to other (higher level) geographies and produce a 'best-fit' match. They have been created by the National Records of Scotland (NRS), based on the WZ boundaries which were produced on behalf of NRS by the Office for National Statistics (ONS). WZs were a new output geography for Census 2011, initially produced using workplace data from the 2011 Census for England and Wales rather than the UK as a whole. They are designed to supplement the Output Area (OA) and Super Output Area (LSOA and MSOA) / Data Zone (DZ) geographies that were introduced with the 2001 Census, and have been constructed from OAs, or sub-divisions of these called postcode-level building-blocks. While OAs are designed to contain consistent numbers of persons based on where they live, WZs are designed to contain consistent numbers of workers, based on where people work. Following publication of WZs for England and Wales, coverage was subsequently extended to include Scotland and Northern Ireland using 2011 Census data to create a UK set of WZs produced by the ONS on behalf of NRS and the Northern Ireland Statistics and Research Agency (NISRA). WZs are designed to be a more suitable output geography for publishing workplace statistics.

The Postal Code Conversion File (PCCF) is a digital file which provides a correspondence between the Canada Post Corporation (CPC) six-character postal code and Statistics Canada's standard geographic areas for which census data and other statistics are produced. Through the link between postal codes and standard geographic areas, the PCCF permits the integration of data from various sources. The Single Link Indicator provides one best link for every postal code, as there are multiple records for many postal codes. To obtain the postal code conversion file or for questions, consult the DLI contact at your educational institution. The geographic coordinates attached to each postal code on the PCCF are commonly used to map the distribution of data for spatial analysis (e.g., clients, activities). The location information is a powerful tool for planning, or research purposes. In April 1983, the Geography Division released the first version of the PCCF, which linked postal codes to 1981 Census geographic areas and included geographic coordinates. Since then, the file has been updated on a regular basis to reflect changes. For this release of the PCCF, the vast majority of the postal codes are directly geocoded to 2006 Census geography. This improves precision of the file over the previous conversion process used to align postal code linkages to new geographic areas after each census. About 94% of the postal codes were linked to geographic areas using the new automated process. A quality indicator for the confidence of this linkage is available in the PCCF.

An DC sector is one of 2 special postcode sectors created for 2011 Census Output. A postcode sector comprises all the unit postcodes that have the same identifier except for the last two characters. Special postcode sectors are created for census output to ensure sectors conform to a minimum threshold and do not cross Council Area boundaries. DC sectors have a minimum threshold of 400 households and 1000 persons. There are 866 DC sectors. Revisions and Corrections Revision to Detailed Characteristic (DC) sector boundaries at boundary between East Renfrewshire and Renfrewshire Council areas. (7 October 2013) DC Sectors S28000494, S28000496, and S280007669 have been amended following a correction to Ordnance Survey BoundaryLine.

This dataset contains the National Statistics Postcode Lookup (NSPL) for the United Kingdom. The NSPL relates current postcodes to a range of current statutory administrative, electoral, health and other statistical geographies via ‘best-fit’ allocation from the 2011 Census output areas. It supports the production of area based statistics from postcoded data. The NSPL is produced by ONS Geography, which provides geographic support to the Office for National Statistics (ONS) and geographic services used by other organisations.

This dataset contains grid references for the 2011 frozen postcode boundaries. Each individual postcode polygon holds a grid reference. Grid references have been assigned by NRS, choosing the building nearest to the centre of the most populous part of the postcode, or the grid reference is from Gridlink®.
