Development
Overview
Development is a central theme in Social Studies for TN TET Paper II, linking economics with geography, civics and contemporary issues. For the exam, you must understand not just definitions but the *multidimensional* nature of development—why income alone does not capture well-being, how sustainability matters for future generations, and how rural-urban disparities shape policy.
Questions typically test conceptual clarity (HDI components, difference between growth and development), factual recall (India's HDI rank, SDG goals) and application (why a state with high income may still rank low on human development). Mastering this topic also helps in geography (urbanisation, migration) and civics (government schemes, constitutional provisions).

Key Concepts
- **Growth vs Development**: Economic growth means increase in GDP/income; development is broader—improvement in quality of life, education, health and freedom. Growth is necessary but not sufficient for development.
- **Human Development**: Amartya Sen's capability approach—development should expand people's choices and capabilities, not just raise incomes.
- **Human Development Index (HDI)**: Composite index by UNDP measuring three dimensions: health (life expectancy), education (mean and expected years of schooling) and standard of living (GNI per capita in PPP dollars). Value ranges from 0 to 1; higher is better.
- **Sustainable Development**: "Development that meets the needs of the present without compromising the ability of future generations to meet their own needs" (Brundtland Report, 1987). Balances economic, social and environmental goals.
- **Sustainable Development Goals (SDGs)**: 17 global goals adopted by UN in 2015 to be achieved by 2030—covering poverty, hunger, health, education, gender equality, clean water, climate action, etc.
- **Rural-Urban Divide**: Rural areas depend largely on agriculture, have lower infrastructure and services; urban areas are industry/service-oriented with better amenities but face congestion, pollution and slums.
- **Urbanisation**: Movement of population from rural to urban areas; driven by push factors (lack of rural jobs) and pull factors (urban employment, education). India's urban population is about 35%.
- **Inclusive Development**: Ensuring benefits of development reach all sections—SC/ST, women, minorities, persons with disabilities—without widening inequality.
