National income and economic growth

The first principle

Every rupee spent on a final good or service becomes somebody's income, and every rupee of income comes from producing something. So an economy's output can be counted three ways, as what is produced, what is earned and what is spent, and the three must give the same total. Growth is the rise in the volume of that output from one year to the next, which is why prices have to be taken out before two years are compared.

The core

What gross domestic product counts

• Gross domestic product (GDP) is the market value of all final goods and services produced within a country's domestic territory in a period. Only final goods are counted, because counting the steel and then the car made from it would count the steel twice; equivalently, each firm's value added is its output minus the intermediate goods it bought.
• The production method adds up the gross value added (GVA) of every sector, from agriculture to finance. The income method adds the incomes created in production: wages of employees, the operating surplus of firms, the mixed income of the self employed, consumption of fixed capital and net taxes on production. The expenditure method adds private final consumption expenditure (PFCE), government final consumption expenditure, gross fixed capital formation (GFCF), change in stocks and valuables, and exports minus imports.
• The two price concepts. GVA at basic prices equals GVA at factor cost plus production taxes (such as land revenue and stamp duty) minus production subsidies. GDP at market prices equals GVA at basic prices plus product taxes (such as the Goods and Services Tax, GST) minus product subsidies (such as the food and fertiliser subsidies).

From domestic product to national income

• Gross national income (GNI) equals GDP plus net factor income from abroad (NFIA), which is the wages, interest, dividends and profits that residents earn abroad minus what non residents earn in India. India's NFIA is negative, because foreign investors earn more in India than Indian residents earn as factor income abroad. Most remittances from Indians working abroad are current transfers, not factor income, so they enter gross national disposable income rather than GNI.
• Net national income (NNI) equals GNI minus consumption of fixed capital, which is the value of machines, buildings and roads worn out during the year. Dividing NNI by population gives per capita income.

Nominal and real, and the deflator

• Nominal GDP values output at the prices of the current year, while real GDP values the same output at the prices of a base year, now 2022-23. Real growth therefore measures the change in volume alone.
• The implicit GDP deflator equals nominal GDP divided by real GDP, multiplied by 100. Growth in nominal GDP is linked to the other two by an exact identity: (1 + nominal growth) = (1 + real growth) × (1 + deflator inflation). For small rates this is close to nominal growth ≈ real growth + inflation.
• Double deflation deflates a sector's output and its inputs separately and takes the difference as real value added. Single deflation applies one price index to value added, which misleads when input and output prices move apart.

The new series with base year 2022-23

• Why base years change. A base year fixes the prices and the weights of sectors. As the economy changes, with new services, new firms and new prices, an old base misstates both the level and the growth of output, so the base is revised roughly once a decade. The earlier bases were 2004-05 and 2011-12; the 2011-12 series, released in January 2015, introduced GVA at basic prices and the company accounts filed with the Ministry of Corporate Affairs (the MCA21 database).
• What changed on 27 February 2026. The National Statistics Office (NSO) of the Ministry of Statistics and Programme Implementation (MoSPI) moved the base to 2022-23. The new series makes wider use of GST returns and other administrative data, and applies double deflation to more sectors.
• The release cycle. Each year's GDP is first estimated in advance in January and February, then provisionally about two months after the year ends, and revised in later years as fuller data arrive; quarterly estimates come about two months after each quarter.

Dimensions

• Demand. Households drive Indian output: private consumption was 56.7 per cent of GDP and fixed investment 31.9 per cent in 2025-26 at current prices (NSO, June 2026).
• Supply. Services produced about 54 per cent of nominal GVA in 2025-26, industry, including construction and utilities, about 26 per cent, and agriculture with mining about 20 per cent, computed from NSO's statement of GVA by sector.
• Sources of growth. Output grows when an economy adds workers, adds capital or uses both more productively. The last, total factor productivity, comes from technology, skills and institutions, and is the only source free of diminishing returns.
• What GDP leaves out. GDP counts market output, so unpaid care work at home, mostly done by women, is left out; it ignores the running down of forests, groundwater and clean air; and it says nothing about who receives the income. GDP measures production, not welfare.
• Federal. State directorates of economics and statistics estimate gross state domestic product (GSDP), which sets State borrowing limits and feeds Finance Commission formulas.

In practice

• Annual growth. On the 2022-23 base, real GDP grew 7.2 per cent in 2023-24, 7.1 per cent in 2024-25 and 7.7 per cent in 2025-26, the last a provisional estimate (NSO, February and June 2026). Nominal GDP in 2025-26 was Rs 346.36 lakh crore, a nominal growth of 8.9 per cent.
• Why sectors matter. Agriculture produces under a fifth of GVA but still employs about 43 per cent of workers (Periodic Labour Force Survey, PLFS, 2025), so slow farm growth holds back incomes even in years of fast GDP growth.
• The latest quarter. Real GDP grew 7.8 per cent in April to June 2026 against 6.9 per cent a year earlier (NSO, 31 August 2026; RBI, Monetary Policy Report, October 2026).
• Per capita income. Per capita NNI at current prices was Rs 2,08,090 in 2025-26, up 7.9 per cent in nominal terms from Rs 1,92,774 (NSO, June 2026).
• A data debate as a case. When the 2011-12 series showed faster growth than many indicators such as credit and industrial output, a 2019 paper by the former Chief Economic Adviser Arvind Subramanian argued that growth had been overstated, which the government's economic advisers rejected. The episode explains the new series' reliance on tax data that can be cross checked.

Issues and way forward

• The informal sector is measured by proxy. Small unincorporated firms are not surveyed every quarter, so their output is often moved in line with formal sector indicators; after a shock that hurts small firms more, such as demonetisation in 2016 or the pandemic, this can overstate growth. Regular use of the Annual Survey of Unincorporated Sector Enterprises (ASUSE) narrows the gap.
• Prices of output are weakly measured. India lacks a full producer price index, so many sectors are deflated with wholesale or consumer prices that do not match what they produce. MoSPI's work on a producer price index, together with double deflation, is the main fix.
• Revisions confuse the public. Estimates are revised as data arrive, and a series break makes old and new growth rates incomparable, so every comparison must name its base year.
• Growth must create jobs. High growth led by capital intensive manufacturing and skilled services adds fewer jobs than growth in labour intensive manufacturing, construction and tourism.
• Beyond GDP. Time use surveys (2019 and 2024) can value unpaid work and MoSPI's environmental accounts can show the natural capital growth uses up; reported beside GDP, they give a truer picture.

Common confusions

• GDP and GNI. GDP counts what is produced inside India by anyone, while GNI counts what India's residents earn anywhere, so the difference is net factor income from abroad.
• GVA at basic prices and GDP at market prices. GVA excludes taxes on products and includes production taxes, while GDP adds the product taxes and subtracts product subsidies, which is why GDP can grow faster or slower than GVA in a year of tax changes.
• The GDP deflator and the Consumer Price Index (CPI). The deflator covers all domestically produced output, including machines and buildings, and its weights change every year, while the CPI covers a fixed basket that households buy, including imported goods.
• Slower growth and contraction. A fall in growth from 8 to 6 per cent means output is still rising, only less quickly; output falls only when growth is negative.

• Use in an answer:
  • Introduction with data: India's real GDP grew 7.7 per cent in 2025-26 and 7.8 per cent in April to June 2026 on the new 2022-23 base, with per capita NNI of about Rs 2.08 lakh (NSO, 2026).
  • Introduction with a source: The United Nations System of National Accounts 2008, which India follows, counts only final output in GDP, which is why intermediate goods are excluded.
  • Conclusion: A new base year, tax data and double deflation make India's GDP more reliable, but its value for policy depends on how well it captures the informal sector that employs most Indians.
  • Conclusion: Growth is a means and not an end, so the measure of success is whether rising output reaches jobs, wages and living standards, which GDP alone cannot show.
