The Organisation for Economic Co-operation and Development (OECD) - 25th Anniversary 14.12.1997

The Organisation for Economic Co-operation and Development (OECD) is an international economic organisation of 34 countries, founded in 1961 to stimulate economic progress and world trade. It is a forum of countries describing themselves as committed to democracy and the market economy, providing a platform to compare policy experiences, seeking answers to common problems, identify good practices and coordinate domestic and international policies of its members.
In 1961, the OEEC was reformed into the Organisation for Economic Co-operation and Development by the Convention on the Organisation for Economic Co-operation and Development and membership was extended to non-European states. Most OECD members are high-income economies with a very high Human Development Index (HDI) and are regarded as developed countries.

The OECD's headquarters are at the Château de la Muette in Paris, France. The stamp depicts the HQs of the OECD and also has a world map showing the countries in the OECD.
