ABSTRACT
In an increasingly global context, policy-makers are constantly seeking reliable comparative data on which to base policies designed to respond to socio-economic and demographic challenges. The statistical agencies of international organisations such as the United Nations (UN), the Organisation for Economic Cooperation and Development (OECD), the World Bank, the European Union (EU) and the Conference of European Statisticians (CES) have been at the forefront in the compilation of data that can be used in policy formation at both national and international levels.
