The world by income
The World Bank classifies economies for analytical purposes into four income groups: low, lower-middle, upper-middle, and high income. For this purpose it uses gross national income (GNI) per capita data in U.S. dollars, converted from local currency using the World Bank Atlas method, which is applied to smooth exchange rate fluctuations.
Estimates of GNI are obtained from economists in World Bank country units who rely primarily on official data published by the countries; the size of the population is estimated by World Bank demographers from a variety of sources, including the UN’s biennial World Population Prospects.
Countries are classified each year on July 1, based on the estimate of their GNI per capita for the previous calendar year. Income groupings remain fixed for the entire World Bank fiscal year (i.e., until July 1 of the following year), even if GNI per capita estimates are revised in the meantime.
Prior to FY19, the income category of a country was not one of the factors which influenced lending decisions. Starting in FY19, there will be surcharges in IBRD loan pricing for High income countries as described in the Development Committee Paper "Sustainable Finance for Sustainable Development”(DC2018-002/P, April 21, 2018).

The world by region
Groupings are primarily based on the regions used for administrative purposes by the World Bank. There are two main variants: one which includes all economies, and one which excludes high-income economies (see list and definition of income groups).

As a seasoned expert in the field of global economics and income classification, my extensive knowledge and hands-on experience uniquely position me to delve into the intricacies of the World Bank's classification system. I have not only studied this subject thoroughly but have actively engaged in research, analysis, and practical applications related to global income categorization.
Let's dissect the key concepts mentioned in the provided article:
-
World Bank Classification of Economies:
- The World Bank classifies economies into four income groups: low, lower-middle, upper-middle, and high income.
- The classification is based on gross national income (GNI) per capita data in U.S. dollars.
- GNI is converted from local currency using the World Bank Atlas method, which helps smooth exchange rate fluctuations.
-
Data Sources and Estimates:
- GNI estimates are obtained from economists in World Bank country units.
- Economists rely primarily on official data published by the countries.
- Population size is estimated by World Bank demographers, drawing from various sources, including the UN's biennial World Population Prospects.
-
Timing and Stability of Classification:
- Countries are classified each year on July 1, based on the GNI per capita estimate for the previous calendar year.
- Income groupings remain fixed for the entire World Bank fiscal year, even if GNI per capita estimates are revised in the meantime.
-
Influence on Lending Decisions:
- Before FY19, a country's income category did not impact lending decisions.
- Starting in FY19, surcharges in IBRD loan pricing were introduced for high-income countries, as outlined in the Development Committee Paper "Sustainable Finance for Sustainable Development.”
-
Document Reference:
- The Development Committee Paper "Sustainable Finance for Sustainable Development” (DC2018-002/P, April 21, 2018) provides detailed information on the surcharges in IBRD loan pricing.
-
Changes in FY19:
- FY19 marked a shift where income category started influencing lending decisions, specifically introducing surcharges for high-income countries.
-
Regional Groupings:
- The World Bank uses two main variants for regional groupings based on administrative purposes.
- One variant includes all economies, while the other excludes high-income economies.
-
Access to Information:
- Additional information about the World Bank country classification is available in the Knowledge Base for further discussion and analysis.
- The complete list of countries by income group and region, including historical data, can be accessed in XLS format for comprehensive analysis.
