Procedures are in place to plan and monitor the quality of the statistical production process.
Under the European Statistical Law
, Member States must provide reports on the quality of the data transmitted. Using the quality reports received from Member States, Eurostat is required to publish the summary reports on the quality of European statistics, including details on the extent to which concepts, definitions and classifications are consistently applied within the European Statistical System.
The quality of European statistics is also described in the metadata
files, which accompany the data published by Eurostat. Statistical processes are in general documented using quality criteria and concepts related to the statistical production. More detailed documentation of the statistical production process is planned using the Eurostat Process Metadata Structure.
Eurostat publishes summaries, known as Quality Profiles
, showing the main quality characteristics for the headline indicators used to monitor the implementation of the Europe 2020 strategy
, and for the indicators used to monitor the EU Sustainable Development Strategy (Sustainable Development Indicators
). The quality profiles are issued by Eurostat in close co-operation with the National Statistical Institutes of the EU-Member States. Quality profiles are available for most of the indicators. In the European Statistical Law
, there is a requirement for sectoral legislation to specify a common structure and frequency for the quality reports.
Eurostat is developing an additional quality approach to better reflect the concept of fit for purpose: "certified quality", standard quality, experimental statistics.
