Overview - Quality


Eurostat's mission is to provide high quality statistics and data on Europe. Accordingly, quality considerations play a central role in Eurostat’s corporate management as well as in the day-to-day statistical operations. This commitment to quality is reflected in ​​​​​​​ Eurostat’s quality policy.

Quality is a multi-faceted, relative concept that affects all aspects of the operation of an institution. Quality in official statistics covers not only the statistical outputs, but also the statistical processes that produce them and the institutional environment in which the statistical authorities operate.

This three-line approach is reflected in the quality framework of the European Statistical System (ESS) that is based upon the European Statistics Code of Practice (CoP). The European Statistics Code of Practice sets the standard for developing, producing and disseminating European statistics, along the lines of the institutional environment, statistical processes and statistical output. A short Glossary explains the main terms used in the CoP.

Statistical authorities, comprising Eurostat, the National Statistical Institutes (NSIs) and Other National Authorities (ONAs) responsible for the development, production and dissemination of European Statistics, are strongly committed to quality – this commitment and high quality awareness are clearly expressed in the Quality Declaration of the ESS that is also included in the Preamble of the CoP.

The Quality Assurance Framework of the European Statistical System (ESS QAF) complements and breaks further down the Code of Practice – it identifies possible methods, tools and good practices that can provide guidance and evidence for the implementation of the CoP.

In the European Statistical System, quality is assessed and reported based on standardised rules, reporting structures and using a common technical environment: the ESS Metadata Handler. The ESS quality reporting standard is the Single Integrated Metadata Structure (SIMS) – for further information please refer to the related section.
