Nevertheless, several high achievers have not only boosted national income, but also had better than average performance on social indicators in areas such as health and education. One way to identify high achievers is to look at countries with positive income growth and good performance on measures of health and education relative to other countries at comparable levels of development. These high achievers include some of the largest countries—Brazil, China and India—as well as smaller countries, such as Bangladesh, Chile, Ghana, Indonesia, the Republic of Korea, Malaysia, Mauritius, Mexico, Thailand, Tunisia, Turkey, Uganda and Viet Nam (figure 3.1). The Republic of Korea, despite lower economic growth than China, had the biggest gains in HDI value.
