Who produces economic statistics? How is the international statistical system organised? Which are the main databases available on the Internet? This chapter outlines the institutional and organisational features of the main producers of economic statistics, starting with international organisations and moving on to review the European and the OECD statistical systems. The division of work between the international organisations and the bodies responsible at the national level for producing statistics (national statistical institutes, other government bodies and central banks) has a significant influence on the availability, and most of all, the quality of the data in existence. Of particular importance during the past 20 years has been the role played by Eurostat and other European institutions, both in setting objectives for the national production of economic statistics, and in making these increasingly comparable internationally. This chapter also contains references to the databases available from international and supranational organisations other than OECD.
