The World Bank is classifying countries in terms of per capita income. Low-income countries are those with a per capita income lower than $ 1,005. The second category is the middle-income group with a per capita income varying from $ 1,006 to $ 12,235. Countries with a PCI of $12236 and above are classified as higher-income economies. An irony about middle-income countries is that many of them are not moving up to the higher income category where the per capita income is above $12736.
