The new OPCS area classifications.

This article introduces the OPCS area classifications based on the 1991 Census. It illustrates the methodology and results in terms of local authority districts. It follows earlier articles in Population Trends that described the production of similar classifications after the 1971 and 1981 Censuses. Each district in Great Britain is classified as both the centre of a small cluster of districts which correspond closely to it and as a member of a cluster within a division of all districts. The list of corresponding districts is set out in full. Information is also given on how to obtain further details of the classification.
