Growth versus Development: HDI, Inequality and Sustainable Development

Growth and development are not the same

Economic growth is a quantitative increase in an economy's output, usually measured as the annual percentage change in real GDP. Economic development is a broader, qualitative idea. It covers better health, education, living standards, freedom, equity and environmental quality, together with structural change: a shift of workers from agriculture to industry and services, urbanisation and institutional strength.

Growth is necessary for development, because it creates resources for health, education and welfare. But it is not sufficient. A country can grow without reducing poverty much, if growth is concentrated in capital-intensive sectors ("jobless growth"), if inequality widens, or if growth damages the environment. Development can also happen at modest growth rates if public action is strong. Kerala achieved high literacy and life expectancy at relatively low income levels in the 1970s and 1980s, a pattern called the "Kerala model".

Amartya Sen defined development as "freedom": expanding people's capabilities, meaning what they are actually able to do and be. Low income is one kind of deprivation; illiteracy, ill health and lack of political voice are others. This thinking shaped the UNDP's Human Development Reports.

Human Development Index (HDI)

The UNDP has published the HDI since 1990. It was designed by Mahbub ul Haq, with Amartya Sen. It has three dimensions:

1. A long and healthy life: life expectancy at birth.
2. Knowledge: expected years of schooling for children and mean years of schooling for adults.
3. A decent standard of living: Gross National Income (GNI) per capita at PPP (log-transformed).

Since 2010, the HDI is the geometric mean of the three dimension indices, so a weakness in one dimension cannot be fully offset by strength in another. Countries are grouped into very high, high, medium and low human development. India is in the "medium" category, and its rank is generally in the 130s among about 190 countries. The 2025 report placed India at 130th for 2023. Treat ranks as report-specific because methodology and data revisions change them.

Related indices published by UNDP:

• Inequality-adjusted HDI (IHDI): discounts the HDI for inequality in each dimension. India loses a substantial share of its HDI value because of inequality.
• Gender Development Index (GDI): the ratio of female to male HDI.
• Gender Inequality Index (GII): reproductive health, empowerment (parliamentary seats, education) and labour market participation.
• Planetary pressures-adjusted HDI (PHDI): adjusts for carbon emissions and material footprint.
• Global Multidimensional Poverty Index: with OPHI (Oxford).

Inequality: measurement and trends

• The Gini coefficient ranges from 0 (perfect equality) to 1 (one person has everything). It is derived from the Lorenz curve, which plots the cumulative share of income against the cumulative share of population. The further the curve sags below the line of equality, the greater the inequality.
• The Palma ratio compares the income share of the top 10% with that of the bottom 40%.
• Consumption vs income inequality: India measures consumption through household surveys. Consumption inequality is much lower than income or wealth inequality.
• Trends: official consumption surveys (HCES 2022–23) show consumption inequality falling since 2011–12. Studies based on tax data (for example by the World Inequality Lab) report rising income and wealth concentration at the top. Present both and note that they measure different things.
• Regional inequality: per capita income in the richest states (Goa, Sikkim, Delhi, Telangana, Karnataka) is several times that of the poorest (Bihar, Uttar Pradesh, Jharkhand). Inter-state divergence is a long-standing concern.
• Kuznets curve hypothesis: inequality first rises and then falls as income grows. Evidence for it is mixed.

Sustainable development

The Brundtland Commission report, *Our Common Future* (1987), defined sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs". It rests on three pillars: economic, social and environmental.

Sustainable Development Goals: adopted by the UN in 2015, the 17 SDGs with 169 targets run until 2030. They replaced the eight Millennium Development Goals (2000–2015). NITI Aayog coordinates SDG implementation in India and publishes the SDG India Index (since 2018), which ranks states. Kerala has consistently been among the top performers, and Bihar among the lowest. The index has shown improvement in the national composite score over successive editions.

Inclusive growth was the theme of the 11th Five-Year Plan (2007–12): growth that is broad-based across sectors and regions and that reaches disadvantaged groups through jobs, services and opportunities.

Indicators of structural change in India

• The share of agriculture in GVA has fallen to under a fifth, but agriculture still employs over 40% of workers (PLFS). This gap shows low productivity per worker.
• Services contribute more than half of GVA.
• Manufacturing has stayed around 15–17% of GVA, which is below the share in East Asian economies at a similar stage. India has followed a "services-led" development path; some economists warn of "premature deindustrialisation" (Dani Rodrik).
• Urbanisation was 31% in Census 2011, rising but low by global standards. A new census has been announced, with houselisting due to begin in 2026 and population enumeration in 2027 (reference date 1 March 2027).

Practice: Mains question

*"High economic growth has not translated into commensurate human development in India." Critically examine. (250 words)*

Hints: compare GDP growth with HDI rank and the IHDI loss; cite health and learning outcomes and female labour participation; give counter-evidence (MPI decline, consumption inequality, improvements in sanitation and electricity); recommend public investment in health and education and job-rich growth.

Analysis: how India can convert growth into development

1. Invest in human capital: public spending on health (below 2% of GDP) and education (around 4–4.6% of GDP) is lower than in East Asian economies at similar stages. Learning outcomes and nutrition are the weakest links (see the GS2 lessons on health, education and hunger).
2. Job-rich growth: encourage labour-intensive manufacturing (textiles, footwear, food processing, electronics assembly) and services such as tourism. This means easing land and labour constraints and supporting MSMEs.
3. Women's participation: raising female labour force participation is among the biggest levers for both growth and development. Safety, transport, childcare and flexible work matter.
4. Balanced regional development: prioritise infrastructure and governance in lagging states. Finance Commission transfers and the Aspirational Districts approach help.
5. Environmental sustainability: the "grow now, clean up later" path is costly. India's commitments (net zero by 2070, the LiFE movement) need to be part of development strategy.

Common prelims traps

• The HDI uses GNI per capita, not GDP per capita.
• The Gender Inequality Index includes the maternal mortality ratio and the adolescent birth rate.
• The World Happiness Report is published by the UN Sustainable Development Solutions Network, not UNDP.
• A Gini coefficient of 0 means perfect equality.

Quick self-test

1. *Can a country have high growth and low development?* Yes. Some resource-rich economies have high incomes but weak health, education and equity.
2. *Which UNDP index penalises inequality?* The Inequality-adjusted HDI (IHDI).
