Statement

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 the General Register Office for Scotland (as it then was) had developed a new process to identify ‘Settlements’ in Scotland. A Settlement was 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 postcode was defined as high density if at least one of the following applied:

• It had more than 2.1 residential addresses per hectare; or

• It has more than 0.1 non-residential addresses per hectare

The second condition is included so that non-residential parts (eg industrial estates) of built up areas could be identified.

These density thresholds were adjusted downwards for some Council Areas (generally those with crofting communities) in order to ensure that at least 95 per cent of postcodes identified as ‘Localities’ in 1991 were selected as high density.

Having identified the individual high density postcodes it was then possible to identify groups of neighbouring high density postcodes containing in total more than 210 residential addresses. These groups were made to include any ‘holes’, ie low density postcodes entirely surrounded by high density ones. Estimates of the population in each group were made, and any group considered to have fewer than 500 residents were discarded.

The threshold densities of 2.1 and 0.1 were found to give a good approximation to the built-up areas identified in previous Censuses using more traditional methods.

These threshold densities were adjusted in two council areas (Eilean Siar and Shetland) where, because of crofting and other factors, settlement patterns vary considerably from the Scottish norm.
