Nigeria is not a member of the Organisation for Economic Cooperation and Development (OECD). The OECD is a group of 38 countries that work together to promote economic growth, trade, and development. It aims to improve the economic and social well-being of people around the world by promoting policies that foster sustainable economic growth, create jobs, and reduce poverty. Nigeria is, however, a member of other international organizations such as the Non-Aligned Nations, the Organisation of Petroleum Exporting Countries (OPEC), and the International Monetary Fund (IMF).
