Since the level of income was insufficient to measure the level of well-being, the focus has been on a model of economic development based on people and the quality of life. Therefore, human-based measurement techniques have been developed for the development. The Human Development Index, published by the United Nations Development Program (UNDP) in its annual reports since 1990, is evaluated with a series of indicators, including the development dimension of a country, per capita income, life expectancy, education and poverty. Based on the Human Development Reports, this study aims to evaluate how the member countries of the Organization of Islamic Cooperation (OIC) which have the ten highest per capita income reflect the human development performance and the richness they possess to human development performance. As a result, it is seen that the six richest OIC Member States were at the highest level of human development, with four countries with higher levels of human development, generally below the OECD average, and not adequately reflecting the growth of GNP for human development. Once studied in the framework of selected sustainable development indicators, it appears that the performance of these countries in terms of sustainable development and environmental objectives is low and that effective policies and improvements are needed in this regard.
