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.
Catalan statistical legislation has reflected this through the current Law on the Statistical Plan for Catalonia 2011–2014, involving an explicit commitment to fostering cost effectiveness in statistical actions, the adequacy of resources and accessibility and clarity in statistical dissemination.
