A 2001 Census Area Statistic (CAS) ward is one of 2 special wards created for 2001 Census Output. These are both created by aggregating output areas and are only best-fit for electoral wards. Using master postcodes, OAs are assigned to electoral wards. The resulting 1,222 aggregations are denoted CAS wards and will fall within a council area boundary and meet a threshold of 20 households and 50 persons.
This dataset portrays the boundaries of ‘Localities’ in Scotland as at the 2001 Census.. There is widespread interest in statistics for the built-up areas in Scotland as most of the population lives in a built-up environment. When the former two-tier local government structure of regions and districts came into being in May 1975, the small local authorities known as large and small burghs were lost. However, Census users stated that there was a need to know the population (and characteristics) of built-up areas. For the 2001 Census the method used to identify Localities was very similar to that used in 1991 in that it was based on identifying groups of high density postcodes.
This dataset contains grid references for the 2001 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®.
A 2001 Census Area Statistic (CAS) sector was one of 2 special postcode sectors created for 2001 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. CAS sectors have a minimum threshold of 20 households and 50 persons, the same minimum threshold as Census Output Areas. There are 1,010 CAS sectors.
This dataset shows the 2001 Census Output Areas (OAs). OAs are the smallest geographical unit for which Census data is released, and as a result, they act as the basic “building-blocks” for the creation of other “higher” geographies, eg Datazones, council areas. The OAs are constructed by aggregating together a small number of postcodes. Because the OAs cover small areas and contain relatively small numbers of households and population (households in the range 20 to 77; population >/= 50), there is only a limited amount of Census data that can be released without infringing confidentiality. 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 the characteristics of the master postcode including its assignment to higher areas and its centroid grid reference. The master postcode is the postcode with the grid reference closest to the centre of the OA weighted by census household. There are 42,604 Census 2001 OAs in Scotland.
This dataset portrays the boundaries of ‘Settlements’ in Scotland as at 2001 Census. There is widespread interest in statistics for the built-up areas in Scotland as most of the population lives in a built-up environment. When the former two-tier local government structure of regions and districts came into being in May 1975, the small local authorities known as large and small burghs were lost. However, Census users stated that there was a need to know the population (and characteristics) of built-up areas. There are 2 datasets which are designed to show the boundaries of ‘urban areas’ in Scotland: ‘Localities’ and ‘Settlements’. While “Settlements’ can go a long way in defining the towns and cities in Scotland, some are very extensive and have grouped together some very large populations. For example the settlement of ‘Greater Glasgow’ has a large population but no breakdown was given of the settlement into any constituent towns or cities such as Airdrie or Paisley. Accordingly, since 2001, the larger ‘Settlements’ have been divided into ‘Localities’ using as a basis the areas so designated in the 1991 Census report ‘Key statistics for ‘localities’ in Scotland (ISBN 0-11-495736-3)’. For the 2001 Census, NRS had developed a new process to identify ‘Settlements’ which were defined as: ‘A collection of contiguous high population density postcodes whose total population was 500 or more, bounded by low density postcodes (or water).’
A 2001 Standard (ST) ward is one of 2 special wards created for 2001 Census Output. These are both created by aggregating output areas and are only best-fit for electoral wards. Where 2001 Census Area Statistic (CAS) wards fall below the ST thresholds (400 households and 1,000 persons) they are merged with neighbouring CAS wards to exceed the threshold. It is also necessary to make a few adjustments to ST wards so as to remove and ‘slivers’ below ST threshold created by differencing ST wards and ST sectors. The processes result in 1,176 ST wards.
The Nomenclature of territorial units for statistics, abbreviated as NUTS (from the French 'Nomenclature des Unités territoriales statistiques') is a geographical classification that subdivides territories of the European Union (EU) into regions at three different levels (NUTS 1, 2 and 3, respectively, moving from larger to smaller territorial units). At the local scale, two levels of Local Administrative Units (LAU) are also defined: LAU 1 and LAU 2 (formerly referred to as NUTS 4 and NUTS 5, respectively). NUTS areas aim to provide a single and coherent territorial breakdown for the collection, development, and harmonisation of EU regional statistics. Further, eligibility for aid from European Structural Funds (for those regions whose development is lagging behind) is assessed at NUTS 2 level. The NUTS classification was originally developed by Eurostat in the early 1970's, however, only gained legal status with Regulation (EC) No 1059/2003 which entered into force in July 2003. A first regular amendment ((EC) No 105/2007) replaced the 2003 version of NUTS with the 2006 version, enacted on 1 January 2008. The current classification is valid until December 31, 2011. For Scottish NUTS areas, the NUTS 1 region covers the whole of Scotland, whereas NUTS 2 subdivides Scotland into 4 regions, and NUTS 3 to 23 regions. Above NUTS 1 is the 'national' level of the EU Member State - the United Kingdom. For Local Administrative Units (LAU) there are currently 41 units at LAU level 1 and 1,222 at level 2. Codes for NUTS regions are prefixed by the characters 'UKM', where 'UK' identifies the member state, the United Kingdom, and 'M' indicates Scotland.
This is the set of postcode boundaries used for 2001 census outputs. The postcode boundaries for census were originally frozen in January 2001 for the purposes of producing census outputs. The dataset contains 139,045 postcode polygons.
A 2001 Standard (ST) sector is one of 2 special postcode sectors created for 2001 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. ST sectors have a minimum threshold of 400 households and 100 persons. There are 859 ST sectors.
