World Bank income classification

Also called: World Bank income groups, World Bank country classification · Topic: Measuring Development: Income, HDI and Sustainability · NCERT: Class 10, Ch 1 "Development"

Meaning

The World Bank income classification puts every economy into one of four income groups: low, lower-middle, upper-middle and high. It does this using GNI per capita (Gross National Income divided by population). This figure is converted into US dollars by the Atlas method (current US$), uses the previous calendar year's data, and is revised every 1 July [2][3].

• GNI per capita = (GDP + net factor income from abroad) ÷ Population

It is the world's most quoted way to label a country "poor" or "rich". Aid, loans and global comparisons often start from it. It also sets the yardstick for India's goal of becoming a high-income country by 2047.

Explanation

How the classification works

• Which income is counted? GNI, not GDP.
• GDP (Gross Domestic Product) is the value of all final goods and services produced inside the country's borders in a year, by anyone.
• NFIA (net factor income from abroad) is the income residents earn abroad minus the income foreigners earn inside the country.

• GNI = GDP + NFIA. So GNI counts what a country's residents earn, wherever they work.

• Worked example (GNI):

• India's GDP = ₹100. Indians earn ₹3 abroad. Foreigners earn ₹5 in India.

• NFIA = 3 − 5 = −₹2. So GNI = 100 − 2 = ₹98.

• Why per capita? Total income hides population size. Per capita income (average income) is total income ÷ population, so countries of different sizes can be compared.

• Timing: groups are revised every 1 July, using GNI of the previous calendar year [2][3]. 218 economies are classified [3].

The four groups: FY2027 thresholds

These were set on 1 July 2026. They are valid until 30 June 2027 and are based on 2025 GNI [2][3].

Group	GNI per capita, Atlas, current US$ (FY2027) [2]
Low income	≤ $1,175
Lower-middle income	$1,176 – $4,635
Upper-middle income	$4,636 – $14,375
High income	> $14,375

• Previous year (FY2026, set July 2025): low ≤ $1,135; lower-middle $1,136–$4,495; upper-middle $4,496–$13,935; high > $13,935.
• Why the thresholds rise every year: they are raised using the SDR deflator (a measure of world inflation, explained below). This keeps them constant in real terms, that is, after allowing for inflation [3].
• So a country must grow faster than world inflation to move up. Keeping pace with it is not enough.

The Atlas method: turning local currency into dollars

• Atlas conversion factor for a year = the average of a country's exchange rate for that year and the two years before, adjusted for the gap between domestic and international inflation [4].
• Domestic inflation is measured by the country's GDP deflator (a price index of everything produced in the economy) [4].

• International inflation is measured by the SDR deflator. This is a weighted average of the GDP deflators of China, Japan, the UK, the US and the euro area. Each is weighted by its currency's share in one SDR (Special Drawing Right, the IMF's reserve asset) [4].

• Purpose: to "reduce the impact of exchange rate fluctuations in cross-country comparisons" [4].

• How it helps:

  • Suppose the rupee falls sharply in one year.
  • A plain one-year conversion would make Indians look suddenly poorer in dollars.
  • Averaging over 3 years smooths out that jump.

• Atlas is not PPP. PPP (purchasing power parity) is an exchange rate that equalises what money can buy. The World Bank classes use Atlas, not PPP.

What moves a country up or down

• Real growth: faster output growth raises GNI per head. Example: Viet Nam, with strong exports and 7–8% GDP growth, moved to upper-middle income in July 2026 [3].
• Exchange rate: Atlas figures are in US$. A weaker local currency lowers the dollar value of income, although 3-year averaging softens the effect.
• Population: a smaller population estimate raises income per head.
• Statistical revisions: better data can change a country's class without any new growth [3].
• Jordan's rebased national accounts showed its economy was nearly 10% larger than earlier thought [3].

• Togo's 2022 census cut its population estimate by 11.7%, which raised income per head. Togo moved up to lower-middle income [3].

• July 2026 movers to upper-middle income: Viet Nam, Philippines, Sri Lanka, Jordan, Micronesia [3].

In India

• India's group: lower-middle income.
• GNI per capita, Atlas method (current US$) [5]:

• $2,360 (2022) → $2,490 (2023) → $2,550 (2024) → $2,760 (2025).

• Same income in PPP terms: $11,600 (2025, current international $) [6]. This is about 4.2 times the Atlas figure.

• Why PPP is higher:

  • Many services cannot be traded across borders, such as haircuts, local transport and rent.
  • Because wages are low in India, these services are cheap.
  • So a rupee buys more at home than its market exchange rate suggests.

• Distance to the next class (FY2027 thresholds):

• Upper-middle: $4,636 ÷ $2,760 ≈ 1.68. India needs about 68% more dollar income per head.

• High income: $14,375 ÷ $2,760 ≈ 5.2 times the 2025 level. This target also rises every year.

• Viksit Bharat@2047: the government aims for India to become a developed, high-income country by 2047, the 100th year of Independence.

• Neighbourhood: Sri Lanka moved to upper-middle income in July 2026. India is still lower-middle [3].
• NCERT error (Class 10, Development): the chapter says high income = "US$ 66,500 and above in 2024", low income = "about US$ 2,300 or less" and India = "about US$ 11,000". None of these match the Atlas thresholds.
• India's $11,000 is close to its PPP figure ($10,580 in 2024, $11,600 in 2025) [6]. So NCERT appears to mix a PPP figure with Atlas-based classes.

• At US$11,000 on the Atlas method, India would be upper-middle, not lower-middle.

• Who measures the base data: MoSPI (Ministry of Statistics and Programme Implementation) produces India's national accounts. The World Bank then converts them to GNI per capita using the Atlas method. MoSPI's base-year revisions and a new census can therefore shift India's figure.

Don't confuse with

• UNDP's HDI income component: it uses GNI per capita in PPP $ (HDR 2025 uses 2021 PPP $; India $9,047 in 2023). The World Bank classes use Atlas, current US$.
• GDP per capita: it counts income produced inside the borders. The World Bank classes use GNI, which counts residents' income. India's NFIA is usually negative, so India's GNI is a little below its GDP.
• "Developed/developing" labels: in 2016 the World Bank stopped using "developing countries" in its World Development Indicators (WDI). It now uses only the four income groups. NCERT calls rich countries "developed" but leaves out the Middle East and certain small countries, because oil wealth or tiny size can give high income without broad development.
• World Bank GNI per capita in PPP ($11,600 for India, 2025) [6]: this is another World Bank figure, but it is not used for income classes.

Prelims Hooks

• The classification uses GNI per capita, Atlas method, current US$. It does not use PPP and does not use GDP.
• Groups are revised every 1 July, based on the previous calendar year's GNI. FY2027: high income > $14,375; lower-middle $1,176–$4,635; low income ≤ $1,175 [2].
• Atlas conversion factor = 3-year average exchange rate (current + two preceding years), adjusted by the domestic GDP deflator relative to the SDR deflator [4].
• The SDR deflator basket is China, Japan, UK, US, euro area. A trap option would add India or Russia [4].
• India = lower-middle income, with GNI per capita $2,760 (Atlas, 2025) [5].
• July 2026: Sri Lanka, Viet Nam, Philippines, Jordan and Micronesia moved to upper-middle income. Togo moved up to lower-middle [3].

Mains Points

• The Viksit Bharat target is steep.
• India must raise Atlas GNI per head more than 5 times, from $2,760 (2025), while the $14,375 threshold keeps rising [2][5].

• This needs sustained high real growth, a stable rupee (because Atlas is in US$) and more manufacturing and formal jobs, not only growth in services.

• Measurement shapes the story.

• India looks very different at Atlas ($2,760) and at PPP ($11,600) in 2025 [5][6].
• Rebasing and census revisions moved Jordan and Togo up a class in 2026 [3].

• So timely, credible statistics (MoSPI base-year revision, a new census) matter for both policy and global standing.

• Income class is necessary but not sufficient.

• A per capita average hides inequality, unpaid care work, public goods and environmental loss.
• Sri Lanka's move to upper-middle income (2026) [3], helped by better health and education indicators, shows that human-capital-led growth can lift a smaller neighbour above a larger economy in per capita terms.
• Answers on development should pair this income class with the HDI and the Multidimensional Poverty Index.
