The European Statistics Code of Practice was adopted by the European Statistical System Committee in February 2005, and promulgated by Commission Recommendation COM(2005)217 on the independence, integrity and accountability of the national and Community statistical authorities. Later, the European Statistical System Committee revised the Code in late September 2011. It is based on 15 Principles covering the institutional environment, the statistical production processes and the output of statistics, A set of indicators of good practice for each of the Principles provides a reference for reviewing the implementation of the Code.
The aim is to guarantee that statistics produced within the European Statistical System are not only pertinent, opportune and necessary, but also satisfy the principles of professional independence, impartiality and objectivity.
The Catalan statistical legislation reflected this Code in the Law on the 2011–2014 Statistical Plan for Catalonia, which included an express undertaking to optimize the cost effectiveness of statistical activity, the appropriateness of the resources and accessibility and clarity in the statistical dissemination. The Code was fully adopted in the 2017–2020 Statistical Plan for Catalonia.
