Revisions and Corrections

Our statistical outputs are sometimes subject to revisions or corrections.

Revisions are generally planned, although there can be occasions when they are unplanned, and are the result of either improvements in statistical methods or the availability of additional data. For example, annual population estimates are revised after a census to take account of the additional information gained from the census results. Details of planned revisions are held within the individual 'About this publication' files alongside each publication.

Corrections are unplanned and occur when errors in either the statistical data or methodology are found after release of the data.

We treat revisions and corrections according to the Scottish Government Statistician Group Revisions Policy, which follows the Code of Practice for Official Statistics.

Any of our statistical outputs that have recently been revised or corrected will be highlighted on this page.

The Office for National Statistics (ONS) Revisions Policies section contains details on ONS' policy on revisions.
