Introduction to 2001 census
This supporting information has been compiled to help users understand and make effective use of the results of the 2001 Census in Scotland.
This is version 2 of the Supporting Information and these pages will be updated to take account of additional information as it becomes available, such as levels of edit and imputation, or to take account of changes to the output, such as footnotes in the output tables. The latest version of the Supporting Information will be available on the Census pages of the NRS website (http://www.NRScotland.gov.uk). For further details Contact Us.
The information is subdivided into a number of topics, which you can navigate using the section headings on the left. At the top of each section page are further links which enable you to access summary information within each section. Alternatively you can use the search function to help you quickly locate the information you are seeking; this is especially helpful if you are seeking information on a particular Census variable or topic.

The One Number Census (ONC) project integrates the 2001 Census counts with the estimated under-enumeration so that all census outputs add to one number - the national population estimate, which has been adjusted for under-enumeration. The primary source in estimating the under-enumeration was the Census Coverage Survey (CCS).
