Quality
In line with the European statistics code of practice and the ESS quality assurance framework, Eurostat carries out controls and validation checks on raw data transmitted by the national data providers to check if the ‘totals’ of a variable across different breakdowns are consistent.
The validation rules consist of a basic set of rules checking the internal consistency of the transmitted files and a further set of rules for analysing the trends, the changes and the potential presence of outliers in the data. Eurostat may apply further validations procedures to assess the quality of the transmitted data.
