Development goals, national income, per capita income, HDI, and sustainability
Development has multiple meanings — it's not just about money. Different people have different goals:
• A landless agricultural worker wants more days of work and better wages
• A prosperous farmer wants better irrigation facilities
• A girl from a rich urban family wants freedom and equal status
Development = improving the well-being and freedom of all people
Sometimes, what is good for one person/group is not good for another:
• Building a dam: good for farmers (irrigation) but may displace tribal communities
• Industrial growth: more jobs but may cause pollution for residents
So development involves trade-offs and choices!
Per Capita Income = Total Income of Country / Total Population
Used by the World Bank to classify countries:
• Rich (developed): Per capita income > $12,056 per year
• Middle income: $1,036 – $12,055 per year
• Low income (developing): < $1,036 per year
India is in the lower middle income category.
Per capita income doesn't tell us how income is distributed. Two countries with the same per capita income may have very different levels of equality.
Example: If a country has 5 people with incomes: ₹10,000; ₹1,000; ₹500; ₹500; ₹500 → Average = ₹2,500 → But 4 out of 5 earn below average!
So average/mean income can be misleading when inequality is high.
The Human Development Index (HDI) was developed by the United Nations Development Programme (UNDP). It ranks countries not just on income but on three dimensions:
1. Long and healthy life → Life expectancy at birth
2. Education → Mean years of schooling + Expected years of schooling
3. Decent standard of living → Gross National Income per capita (PPP $)
HDI score: 0 (lowest) to 1 (highest)
Punjab has higher per capita income than Kerala.
But Kerala has better literacy rate, lower infant mortality, higher life expectancy.
Which state is more "developed"? It depends on what you value!
Kerala shows that high income is not the only path to well-being — good public services (health, education) matter equally.
| Indicator | What it Measures | India's Status |
|---|---|---|
| Life Expectancy | Average years a person is expected to live | ~70 years (improving) |
| Literacy Rate | % of population that can read and write | ~77% (Gender gap remains) |
| Infant Mortality Rate (IMR) | Deaths per 1000 live births under age 1 | ~28 (decreasing) |
| Net Attendance Ratio | % of children enrolled in school | Improving |
| GDP (Gross Domestic Product) | Total value of goods/services produced in a country in a year | India = ~$3.7 trillion (5th largest) |
Sustainable development means meeting the needs of the present without compromising the ability of future generations to meet their own needs.
The key question: Are we using resources responsibly so our children and grandchildren can also have a good life?
Environmental sustainability: Not exhausting natural resources (water, forests, minerals, clean air)
In Punjab and Haryana, farmers have over-extracted groundwater for agriculture. Water levels are falling rapidly. The next generation may face water scarcity.
The development of the current generation (more food production, more income) is at the cost of future generations — not sustainable!
