The Organisation for Economic Co-operation and Development is an intergovernmental economic organisation with 38 member 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, seek answers to common problems, identify good practices and coordinate domestic and international policies of its members. Generally, OECD members are high-income economies with a very high Human Development Index and are regarded as developed countries. As of 2017, the OECD member countries collectively comprised 62.2 % of global nominal GDP and 42.8 % of global GDP at purchasing power parity. The OECD is an official United Nations observer.
