Documents describe the principles for statistical revisions and the correction of publication errors, defining the basic concepts of revision and publication error, their types, and how to publish and notify users of changes.
These rules may be amended and supplemented for consistency with guidelines of the European Union or other international organizations and due to changes in data collection methods or data sources.
The European Statistics Code of Practice obliges the member states of the European Union to pursue a revising policy that affects, among other things, the accuracy and reliability of the data presented by statistics. A properly conducted revision is intended to make available higher quality statistics, compiled from the most current source data, prepared according to new calculation methods and/or classifications.
