Reader’s guide
This report uses two classifications of countries around the world. It makes use of the World Bank income classes that categorise economies into high-income, upper middle-income, lower middle-income, and low-income countries. Countries with a gross national income (GNI) per capita of $1,025 or less in 2018 are considered as low-income. Lower middle-income countries have a GNI per capita between $1,026 and $3,995. Upper middle-income countries have GNI per capita between $3,996 and $12,375. Finally, high-income countries have a GNI per capita of $12,376 or more. Figure 1 illustrates how countries are categorised according to this classification.
