Frozen Postcode 2011

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.

Geography – 2011 Census Boundaries

dataset Dataset
Statement

The history of creating and maintaining the postcode dataset is contained in the live postcode boundary dataset. Because we built up geographies such as council areas from postcodes we were aware of situations where the NRS council are boundary did not match exactly with the OS BoundaryLine product. To ensure consistent alignment of the Census geographies with OS BoundaryLine the following postcode boundaries required minor amendment:

Those that did not align with BoundaryLine’s council boundaries

Those that did not align with BoundaryLine’s Mean Low Water

Those that did not align with BoundaryLine’s portrayal of lochs

Those that did not align with BoundaryLine’s portrayal of estuaries and rivers

Overall just under 9,000 amendments were made but the amendments did not affect the assignment of any higher area geographies.

A boundary change between Glasgow City Council and East Dunbartonshire Council came into force in 1 April 2011 after Census Day (27 March 2011) has been included because of its close proximity to Census Day.

The boundaries are available for two geographic extents:

Extent of the Realm (EoR)

The boundaries in this dataset are to the Mean Low Water mark so that the coastline is extended to be consistent with Local Authorities.

and

Clipped to the coastline with inland water removed (MHW)

The boundaries in this dataset have been clipped to the coastline (Mean High Water Mark) with inland water removed. This version closely represents map users expectations of how a coastal boundary should look.

The Standard Area measurements were used to identify bodies of inland water and subsequently removed.
