What is the difference between per capita income and HDI?

Per capita income = National Income ÷ Population — measures average income only. HDI (Human Development Index) measures three dimensions: income (GNI per capita), education (literacy + schooling years), and health (life expectancy). HDI is more comprehensive — a country can have high income but low HDI if people have poor health and education (e.g., oil-rich nations with low education).

What is sustainable development and why is it important?

Sustainable development meets present needs without compromising future generations' ability to meet theirs. Important because: non-renewable resources (coal, oil) are finite; environmental degradation (pollution, deforestation) reduces future productivity; over-exploiting groundwater/forests today leaves nothing for tomorrow. Solutions: renewable energy, sustainable farming, pollution control, biodiversity protection.

What are the different development goals for different categories of people?

Development goals vary by circumstance: Farmers want higher crop prices, irrigation, and land security. Industrial workers want better wages, job security, and safe working conditions. Urban professionals want career growth and better infrastructure. Women want equal rights, safety, and economic independence. Students want quality education and job opportunities. Development must satisfy all groups, not just the majority or the rich.

Development — Concepts and Indicators

Economics • Class 10 Social Science • NCERT • CBSE

Development means progress or improvement in people's lives — not just economic growth. While per capita income measures average income, the Human Development Index (HDI) measures development more comprehensively using income, education, and health indicators.

Key Formulas

Per Capita Income = National Income / Population
HDI = composite index of Life Expectancy + Education + Income
HDI score: 0 to 1 (higher = more developed)
