Data Quality

Data collected in a census does inevitably contain inconsistent or incomplete information and, as a result, adjustments were made to some of the 2001 Census data using the Edit and Imputation and the One Number Census processes.

The information on Census Variables and the reports on Ethnicity Coding detail the extent to which adjustments were made to the various items collected on the Census Form.

2001 Census Variables

The question on ethnicity on the form for the 2001 Census divided answer categories into five sections. Form-fillers were asked, first, to select a section and, second, to tick a box within that section. For one tick box in each section the form-filler had also to write some descriptive text. There were 14 tick boxes in all.

There was also the same number of categories in one of the main classifications of ethnicity used in output from the census. In general, each output category corresponded to a tick box on the form in that, in the main, a person with a tick in a box would be assigned to the corresponding output category. The main exceptions to this general rule were the output categories of 'Any Mixed background' and 'Other ethnic group'

Updates

In order to further assist users in interpreting the census results non-response rates for all census questions for each Council Area in Scotland are available. The figures relate to the census database before the addition of any records by the One Number Census process.

Where an individual did not respond when he or she should have to a specific question, a response has been provided by edit or imputation.

Proportions of persons in each Output Area added by the One Number Census process are also now available.

Note: The files below have been made available as Excel spreadsheets. When opening the spreadsheet files your browser, depending on how it's been configured, will prompt to either open the file or save it to disk. Maximum file size is 2.6 MB.
