Revisions log


We follow the UK Statistics Authority Code of Practice for Official Statistics. The code requires us to publish a revisions policy which explains the nature and extent of revisions.

Since revisions are a normal and inevitable part of statistical publications, our revision policy will allow you to acknowledge and plan for the revisions accordingly.
