Dataset is complete for Scotland. Care should be taken when using this dataset with lookups to other postcode based geographies. Some postcode unit boundaries have changed since intermediate zones were created and therefore exact match of the boundaries are unlikely.

Statement

Not all statistics are suitable for release at the data zone level because of the sensitive nature of the statistics or for reasons of reliability and it soon became apparent that a statistical geography between data zone and local authority was required - the intermediate zone. The dataset was originally created by St. Andrews University and a full report describing the production of the intermediate zones is available at: http://www.scotland.gov.uk/library5/society/snsigbi-00.asp.

When designing the intermediate zones, the following criteria were taken into account:

1. Intermediate zones must be built up from data zones and should nest within local authorities (as the exist in 2001).

2. They must not be made up of non-contiguous areas (except where this is unavoidable, as in the case of islands).

3. They must contain between 2,500 and 6,000 household residents.

4. Significant physical boundaries such as motorways, railways and valleys should be taken into account.

5. The shapes of intermediate zones should be reasonably compact to allow the make-up of the area to be easily understood.

6. Relationship to Scottish parliamentary constituency boundaries (this is not always possible, as data zones do not nest within these constituencies).

7. Where possible, intermediate zones should be co-extensive with small settlements of 3,000 to 6,000 residents.

8. Where possible, intermediate zones should group together data zones with similar characteristics, as measured by the Scottish Index of Multiple Deprivation.

Scottish Parliamentary Constituencies were used as a starting point for the intermediate zones and were refined using the Scottish Index of Multiple Deprivation, settlement boundaries and background mapping.

A consultation with Community Planning Partnerships was then undertaken, where they were asked to quality assure the geography based on local knowledge and suggest changes where appropriate. All changes were accepted as long as they met the population threshold, data zone building block criteria and nested into local authority boundaries (as at the 2001 Census). In practice, it was not possible to satisfy all criteria at once, and some compromise was necessary. The first two criteria were always observed, though in a few cases intermediate zones outside the household population range were accepted if the Community Planning Partnership made a strong case.

Names were also provided for the intermediate zones by 26 of the 32 Community Planning Partnerships when the zones were created. Further names were added in March 2005 and February 2006. In March 2010 and update was provided for the intermediate zone names in Moray.

This dataset also includes an area field with the value given in hectares. This area is the 'standard' area which was calculated from Census Output Areas and then assigned to Intermediate Zones through a look up table. This follows the Office for National Statistics (ONS) Standard Area Measurement methodology, as agreed in 2005. This was done to ensure that total areas remained consistent when comparing geographies. For more information on ONS Standard Area Measurement, please see http://www.ons.gov.uk/about-statistics/geography/products/geog-products-other/sam/index.html.

The dataset is managed by the Scottish Government's Geographic Information Science and Analysis Team (GI-SAT), who carry out any required updates at the request of the Office of the Chief Statistician (OCS), Small Area Statistics Branch. Attributes included within the dataset are as follows:

IZ_CODE: Unique identifier given to each of the 1,235 intermediate zones.

IZ_NAME: Name given each intermediate zone.

STDAREA_HA: Area in hectares, calculated from Output Areas.
