Description: 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®.
Description: This is the set of postcode boundaries used for 2011 census outputs. The postcode boundaries for census were originally frozen in January 2011 but have since been re-aligned to Ordnance Survey 2011 BoundaryLine for the purposes of producing census outputs. The re-alignment work ensures consistency of approach with the Office of National Statistics (ONS) and the Scottish Government (SG). The improvements made to the dataset as a result of re-alignment did not affect any existing higher area assignments in the Postcode Index although there will be some very minor differences in the boundaries if compared against the 2011_1 set of postcode boundaries already published. The dataset contains 145,690 postcode polygons. Revisions and Corrections Revision to postcode boundaries at boundary between East Renfrewshire and Renfrewshire Council areas (7 October 2013) Postcodes PA2 7DA, PA2 7TX, PA2 8TY, G53 7TH, G78 1HJ, and G78 1TJ have been amended following a correction to Ordnance Survey BoundaryLine.
Description: This dataset shows the 2011 Census Output Areas (OAs) Population Weighted Centroids.
An individual Output Area generally covers a sufficiently small area (subject to meeting minimum population / household counts) so that user defined or ad-hoc areas can be created while maintaining a sufficient level of quality. National Records of Scotland (NRS) produces only one set of OAs and creates all other output geographies using the OA as the building brick. Each OA is assigned to an area in a higher geography by first selecting one of the postcodes in the OA as a ‘master’ postcode. The OA inherits all of the characteristics of the master postcode including its assignments to higher areas and its grid reference.
The master postcode was selected using an algorithm which calculates the postcode centroid within an OA which has grid references closest to the population-weighted centre of the OA.
An anomaly was discovered in the 2011 Census Output Area (OA) codes which were published on 15 August 2013. The anomaly meant that, whilst all the current 2011 Census OA codes were unique, they did not always run in sequential order by council area. We decided to replace the codes with new ones that start at S00088956 and end with S00135306.
Description: A 2011 LC sector was 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. LC sectors have a minimum threshold of 20 households and 50 persons, the same minimum threshold as Census Output Areas. There are 1,012 LC sectors.
Corrections and Revisions
Revision to Local Characteristic (LC) sector boundaries at boundary between East Renfrewshire and Renfrewshire Council areas. (7 October 2013)
LC Sectors S29000556, S29000558, and S29000870 have been amended following a correction to Ordnance Survey BoundaryLine.
Description: 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.
Description: The geography of Scotland comprises the mainland plus many islands. Some of these islands are inhabited and through time their inhabited/uninhabited status can change.
As statistics for individual islands could reveal details about individual people, the individual islands have been grouped into 56 ‘island groups’ for 2011 Census output.
Revisions and Corrections
An anomaly was discovered in the 2011 Island Groups boundaries where the boundaries for some of the island groups were not including the mainland part of the island group.
Description: 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.
