1991 Census

Summary local information from the 1991 Census.

This page includes a statistical profile of the PDF Document City & County of Swansea (PDF, 107KB)Opens new window from the 1991 Census. Whilst the current unitary authority did not exist until April 1996, the City & County profile was constructed using the constituent wards of the former Swansea and Lliw Valley Councils.

Equivalent 1991 Census profiles were compiled for the 36 electoral divisions or wards in Swansea (2001 Census base) using the relevant ward or enumeration district level data from the 1991 Census. These profiles are also available on this page. 

1991-2001 comparisons

The broad picture of population change can be followed from census to census. This page also contains a brief summary of the PDF Document key changes between 1991 and 2001 (PDF, 83KB)Opens new window in the Census results for the City & County of Swansea. The summary gives an indication of how Swansea, and society in general, changed over those ten years.

However, each census primarily provides a 'snapshot' at the time it was taken, and does not necessarily provide a good source of detailed information about change.  Changes are made at each census to the questions, the categories used to present results, definitions, methodology and geography - all of which require caution when comparing data from 1991 and 2001.  Some of these differences are described below:

  • A change in the population base used: the 1991 Census counted students at their parents' address whilst the 2001 Census counted students at their term-time address.
  • Usual residents and visitors: the 1991 Census collected information on both usual residents and visitors present on Census night, whilst the 2001 Census only collected information on usual residents.
  • Post-Census adjustment methods: the results of the 2001 Census were adjusted to account for under-enumeration via the Census Coverage Survey. The 1991 Census results were not subject to the same adjustments.
  • Sample processing: output from some of the 1991 topics was based on a 10% sample. Unlike the 1991 Census, there was no sample processing of data in 2001.
  • Boundary changes: some changes occurred in certain areas of Swansea between 1991 and 2001, which means that statistics which apparently refer to the same named area actually relate to different boundaries.
