REVAMP" data-analytics-asset-type="web-content"> <p class="ecl-u-type-paragraph">Statistical data are generally revised to incorporate new and improved sources of information. The revision of published data is an essential part of producing high quality statistics.</p> <p class="ecl-u-type-paragraph">In 2023, Eurostat adopted a general revision policy that says that:</p> <p class="ecl-u-type-paragraph">‘<span class="ecl-u-type-bold">Revision of data is a normal process in the production of European statistics to improve their quality. Revisions follow standard, well-established and transparent procedures.</span>’</p> <p class="ecl-u-type-paragraph">Eurostat’s revision policy is based on the <a class="ecl-link" href="https://ec.europa.eu/eurostat/web/quality/european-quality-standards/european-statistics-code-of-practice">European Statistics Code of Practice</a> (CoP) which offers guidance on release dates and revisions of statistics, for example for the indicators under principles 6, 8, and 12 of the CoP.</p> <p class="ecl-u-type-paragraph">Eurostat has also published <a class="ecl-link" href="https://ec.europa.eu/eurostat/web/products-manuals-and-guidelines/-/ks-ra-13-016">guidelines for the European Statistical System for the revision of PEEIs</a> (Principal European Economic Indicators). They present the theoretical and practical aspects of routine, major and non-scheduled revisions, in accordance with the CoP.</p> <h2 class="ecl-u-type-heading-2">Scope and objectives </h2> <p class="ecl-u-type-paragraph">Eurostat seeks to apply its revision policy to all statistical domains, aiming to:</p> <ul class="ecl-unordered-list"> <li class="ecl-unordered-list__item">ensure that revisions are carried out in a more <span class="ecl-u-type-bold">harmonised</span> way</li> <li class="ecl-unordered-list__item">provide clear <span class="ecl-u-type-bold">documentation</span> for users</li> <li class="ecl-unordered-list__item">provide transparent information on the <span class="ecl-u-type-bold">reasons</span> for, and the <span class="ecl-u-type-bold">scheduling</span> of, statistical revisions.</li> </ul> <h2 class="ecl-u-type-heading-2">Publishing information on data revisions</h2> <p class="ecl-u-type-paragraph">Eurostat publishes information on data revisions for each statistical domain in the metadata files under the headings ‘Data revision – policy’ and ‘Data revision – practice’. These metadata can be found attached to folders or individual datasets in <a class="ecl-link" href="https://ec.europa.eu/eurostat/web/main/data/database">Eurostat’s database</a> (look for the <i aria-hidden="true" class="estat-icon-metadata"></i> symbol) or can be accessed directly from a dataset.</p> <p class="ecl-u-type-paragraph">Sometimes this information is also presented in ‘Statistics Explained’ articles or elsewhere on the Eurostat website.</p> <p class="ecl-u-type-paragraph">For some statistical domains, Eurostat also analyses revisions when assessing the quality of data.</p> <h2 class="ecl-u-type-heading-2">Types of revisions</h2> <p class="ecl-u-type-paragraph">European statistics can be revised through:</p> <ul class="ecl-unordered-list"> <li class="ecl-unordered-list__item"><span class="ecl-u-type-bold">routine revisions</span> – when additional information from the providers of the source data becomes available</li> <li class="ecl-unordered-list__item"><span class="ecl-u-type-bold">major revisions</span> – these are planned and pre-announced to users (including information on the specific characteristics of the revision policy and practice relevant to the statistical domain in question)</li> <li class="ecl-unordered-list__item"><span class="ecl-u-type-bold">unscheduled revisions</span> – often occurring when errors are detected.</li> </ul> <h3 class="ecl-u-type-heading-3">Routine revisions</h3> <p class="ecl-u-type-paragraph">These are changes in published statistics that are part of the regular data production process, for example planned updates of already published national statistics.</p> <p class="ecl-u-type-paragraph">European aggregates are revised when EU countries transmit new statistics to Eurostat, usually according to an agreed schedule.</p> <p class="ecl-u-type-paragraph">A seasonal adjustment process can be another reason for a revision. In this case, revisions should follow the requirements specified in the <a class="ecl-link" href="https://ec.europa.eu/eurostat/web/products-manuals-and-guidelines/-/ks-gq-15-001">European Statistical System guidelines on seasonal adjustment</a>.</p> <h3 class="ecl-u-type-heading-3">Major revisions</h3> <p class="ecl-u-type-paragraph">Major revisions of published statistics occur less often. They can be triggered by: </p> <ul class="ecl-unordered-list"> <li class="ecl-u-type-paragraph ecl-unordered-list__item">the availability of <span class="ecl-u-type-bold">new data</span> that is only collected infrequently (every 5 to 10 years), such as a census, input-output tables or labour cost surveys </li> <li class="ecl-u-type-paragraph ecl-unordered-list__item">an update to the weightings for the <span class="ecl-u-type-bold">base year</span> of an index series (typically every 5 years) </li> <li class="ecl-u-type-paragraph ecl-unordered-list__item">a change in the <span class="ecl-u-type-bold">concepts</span>, <span class="ecl-u-type-bold">definitions</span> and/or <span class="ecl-u-type-bold">classifications</span> used to produce the data series. For example, when there is a new classification or version of a classification, a change in international statistical standards, or a new EU statistical regulation.</li> </ul> <p class="ecl-u-type-paragraph">Major revisions can also occur for a combination of these reasons, alongside improvements to the statistical methodology. The overall aim is to ensure the best possible match between published statistics and the phenomena they measure.</p> <p class="ecl-u-type-paragraph">Major revisions are usually planned well in advance. Users are informed in good time and warned when they can expect considerable changes to the time series of European statistics. If possible, users are also informed about the likely impact of major revisions.</p> <p class="ecl-u-type-paragraph">In the statistical domain of <span class="ecl-u-type-bold">national accounts</span>, benchmark revisions are treated as major revisions.
