Development

Why This Matters

Ask five different people one simple question: “What would make your life better?” You will get five different answers. A farmer who depends on rain will say, “Give me water, even in a dry year.” A girl in a strict home will say, “Let me study as far as I want, just like my brother.” A young man with a degree but no job will say, “Just give me steady work.” A factory owner will say, “I need more electricity and cheaper labour.” A family living near a river will say, “Please do not flood our village to build a big dam.”

Notice something strange. The factory owner wants more electricity from a big dam. But the family near the river is terrified of that exact same dam. The same project is “progress” for one person and “disaster” for another.

This is the quiet secret of this whole chapter: development does not mean the same thing to everyone. What is good for one person can be useless, or even harmful, for someone else. So when a leader says “we want to develop the country”, we must always ask: develop for whom? And how will we even measure it?

These are not just exam questions. They are questions about the kind of country you will grow up in — whether it has good schools, clean air, fair treatment and safety for everyone, or just more money in a few pockets. This chapter is where you learn to think about all of that clearly. Let us begin.

The Big Idea

Different people want different things from development, and the same change can be good for one person but bad for another — so there is no single goal that fits everyone. Almost everyone wants more income, but people also want other things money cannot directly buy: equal treatment, freedom, security, respect, and a clean environment. To compare whole countries, the World Bank uses per capita income (the average income — total income divided by the number of people), because it tells us how much an average person earns. But averages have a big weakness: they hide inequality — two countries can have the exact same average income while one shares it fairly and the other has a few rich people and many poor ones. So we also use other measures. The UNDP’s Human Development Index (HDI) combines three things into one score: health (how long people live), education (how much they learn), and income. We also need public facilities — clean air, safety, good schools and hospitals nearby — because money in your own pocket cannot buy these; they must be provided for everyone together. Finally, development must be sustainable: we must not use up groundwater, oil and other resources so fast that nothing is left for our children. True development is about a better life for everyone, today and tomorrow — not just a bigger number for a few.

Let’s Break It Down

Before we begin, let us refresh three small words this whole chapter leans on. They sound simple, but if their meaning is fuzzy, everything later gets fuzzy too.

Different people, different goals

Let us start with the most important idea in the chapter. Imagine you ask several different people what “development” or “a better life” means to them. Their answers will not match. Each person wants whatever is most important for their own life.

A landless labourer wants more days of work, better wages, and a good school for their children. A prosperous farmer wants higher prices for crops and cheap workers. A girl in a strict family wants the same freedom her brother has. None of them is wrong. They just have different needs.

Now here is the part that surprises students. Sometimes two people’s goals do not just differ — they actually clash. What one person calls development, another calls destruction. Figure 1.1 below shows one clear example.

The picture below shows how a single project can pull two people in opposite directions:

So two things are now clear. First, different people can have different goals for development. Second, what is development for one may not be development for another — it can even be destructive for the other. Keep this in mind for the whole chapter. It is the reason measuring development is so tricky.

Here is a quick check to make sure this idea has landed:

Income and other goals

Look again at what those different people wanted: steady work, better wages, a fair price for crops. Strip away the details, and most of these come down to one thing — more income. That makes sense. With more income, you can buy more of the things you need: food, clothes, a phone, medicines, a better house.

So income matters a lot. But here is the catch. If you watch carefully, people want many things that money cannot directly buy. They want to be treated equally, not insulted because of their caste, religion or gender. They want freedom — the ability to decide their own life. They want security — to feel safe and to know their job will not vanish tomorrow. They want respect from others. And they want a clean environment — air they can breathe, water they can drink.

Think about a real choice. Suppose you are offered a job far from home with very high pay, but no job security and no time for family. Would you take it without thinking? Probably not. You would also weigh safety, your family, free time, and whether the work feels respectable. Income is only one of the things you care about. Figure 1.2 below shows this clearly.

The picture below puts income in the centre and the other goals all around it:

So development is about a mix of goals, not income alone. This is true for one person, and it is also true for a whole country. A nation that grows richer but treats half its people unfairly, or chokes them in polluted air, is not fully “developed”. Remember this: more income is a means to a good life, not the whole of it.

How do we compare different countries?

Now a practical problem. Newspapers call some countries “developed” and others “underdeveloped”. If development means different things to different people, how can anyone rank whole countries?

Here is the simple answer used most often: income. The idea is that more income lets people buy more of whatever they need. So a country where the average person earns more is treated as “more developed”. Income is not the only thing that matters, but it is easy to measure and it captures a lot, so we start with it.

But there is a trap. Suppose we just add up the total income of everyone in a country. A huge country with many people will of course have a big total — but that does not mean each person is well off. A small rich country may have a smaller total income but a very comfortable life for each person. So total income is misleading. Figure 1.3 below shows why.

The picture below shows why total income cannot be compared fairly across countries:

So we use per capita income — also called average income. The word “per capita” just means “per head”, that is, per person. The formula is simple.

Per capita income = Total income of the country ÷ Total population

This is exactly the measure the World Bank uses to sort countries in its World Development Reports. Countries with a very high per capita income are called rich (high-income) countries, and those with a very low per capita income are called low-income countries. India, with a middling per capita income, falls in the lower-middle-income group. The rich countries (leaving aside a few special cases) are the ones usually called “developed”.

Let us practise the calculation, because it appears in exams almost every year:

The big weakness of averages — they hide inequality

The average is handy, but it has a serious flaw. An average can hide huge differences between people. Two countries can show the exact same average income and yet feel completely different to live in. How? Because the average does not tell you how the income is shared.

This is the classic NCERT example, and it is worth understanding deeply. Look at two countries, A and B. To keep it simple, each has just five citizens. Both turn out to have the same average income — yet one is a decent place to live and the other is not. Figure 1.4 below makes the difference jump out.

The picture below shows two countries with the same average but very different lives:

Ask yourself the NCERT question: would you be equally happy in both countries? Country A and Country B have the same average income. But in Country A, everyone earns roughly the same, so no one is desperately poor. In Country B, one person earns a fortune while four people are extremely poor. If a lottery decided which citizen you became, you would almost certainly end up poor in Country B. So most of us would pick Country A — even though both have the same average.

This is the key lesson. Average income tells us nothing about how that income is shared among people. A country’s average can even keep rising while most people get poorer, if one or a few people get hugely richer. That is why income, on its own, is an incomplete measure of development. We need to look further.

Income is not enough — other indicators

Here is where it gets really interesting. The Indian states of Haryana, Kerala and Bihar tell a story that income alone cannot explain. By per capita income, Haryana is the richest of the three and Bihar the poorest. So by income, Haryana should be the “most developed”. But look at the things that matter for an actual human life, and the picture changes.

The comparison below puts income next to health and education for these three states:

Look carefully. Haryana has more income than Kerala. Yet in Kerala, only 6 babies out of every 1,000 die before their first birthday, while in Haryana the number is 28 — nearly five times higher. And Kerala has more people who can read and write. So Kerala, with less income, gives its people longer, healthier, better-educated lives than richer Haryana. Income alone clearly misses something huge.

Before going on, let us be sure these health and education terms are clear, because the chapter uses them again and again:

Public facilities — why money in your pocket can’t buy everything

So how can richer Haryana fall behind poorer Kerala on health and education? The answer reveals one of the deepest ideas in economics. Money in your own pocket cannot buy some of the most important things in life. Those things have to be provided for everyone together.

Think about it. Can your personal money buy you clean air if the whole city’s air is polluted? No — you breathe the same air as everyone else. Can your money alone protect you from an infectious disease if your whole neighbourhood is unhealthy? No — germs do not check your bank balance. Can your money give you a good school if there is no decent school anywhere near your village? Only if your family is rich enough to send you far away — which most families cannot do. Figure 1.5 below shows why some things simply cannot be bought one person at a time.

The picture below sorts the things money can buy from the things it cannot:

This is why Kerala does so well. It has built good public health and education facilities that everyone can use. A state can have lower average income but still give its people a far better life — if it spends wisely on facilities shared by all. So income tells only part of the story. We must also ask: are there good schools, hospitals, clean water and safe streets that everyone can actually use?

The Human Development Index — putting it all together

We have now seen that development needs more than income. It needs health and education too. But a long list of separate numbers is hard to use. What we want is a small set of the most important things, combined into one clear measure.

That is exactly what the Human Development Index (HDI) does. It is published every year by the UNDP (United Nations Development Programme) in the Human Development Report. The HDI takes three of the most important things about a person’s life — health, education, and income — and combines them into a single score, which is then used to rank countries. Figure 1.6 below shows the three pieces and how they join.

The picture below shows the three dimensions of the HDI flowing into one score:

This explains a result that shocks many students. India’s neighbour Sri Lanka, a much smaller country, ranks far ahead of India on human development — because its people live longer and are better educated. And countries like Nepal and Bangladesh, which have lower per capita income than India, still beat India on life expectancy. So a smaller or poorer country can be ahead of a bigger, richer one — because development is about people, not just money.

The sustainability of development

There is one last question, and it may be the most important of all. Suppose a country is developed today. Can it stay that way forever? Only if its development is sustainable — meaning it can be kept going for our children and grandchildren, not just for us.

Here is the worry. The way we are growing right now uses up the Earth’s resources very fast. And resources come in two kinds, with two different dangers. Let us be careful here, because students often miss why even “renewable” resources can run out.

The comparison below shows the two kinds of resources and how each can be lost:

Take groundwater. It is renewable — rain soaks into the ground and refills it. But if farmers and cities pump out water faster than the rain puts it back, the level keeps dropping. In India, about one-third of the country is already overusing its groundwater, and many areas have seen the water level fall by several metres. So even a renewable resource can be drained dry if we are greedy. Figure 1.7 below shows exactly how.

The picture below shows groundwater being overused faster than rain can refill it:

Now take non-renewable resources like crude oil and coal. These are even more final. There is a fixed amount in the Earth, formed over millions of years, and nature cannot make more on any timescale that helps us. The world’s known oil reserves, used at the present rate, are estimated to last only a few more decades. Once they are gone, they are gone. India, which has little oil of its own, must import most of it — so when world oil prices rise, the whole country feels the pinch.

This is why scientists, economists and thinkers now study sustainability together. There is a beautiful line that sums it up: “We have not inherited the world from our forefathers — we have borrowed it from our children.” Pollution and a drained planet do not stop at any border, so this is everyone’s problem. True development must leave enough behind. Growing today by ruining tomorrow is not real development at all.

Summary

Here are the key ideas of this chapter. You should now be able to explain each one in your own words.

• Different people have different goals for development, and the same change can be good for one person but harmful for another (a big dam helps a factory owner but floods a tribal family). So we must always ask: development for whom?

• People want more income, but they also want equal treatment, freedom, security, respect and a clean environment — things money cannot directly buy. Development is a mix of goals, not income alone.

• To compare countries, the World Bank uses per capita income = total income ÷ population. It uses the average (not total) income because countries have different populations.

• Averages hide inequality. Two countries can have the same average income but very different lives, because the average says nothing about how income is shared.

• The UNDP’s Human Development Index (HDI) combines health (life expectancy), education (years of schooling) and income into one score. This is why a poorer country like Sri Lanka can rank higher than India.

• Public facilities like clean air, safe streets and good schools cannot be bought with personal money. They must be provided for everyone together — which is why Kerala beats richer Haryana on health and education.

• Development must be sustainable. Even renewable resources (groundwater) run out if used faster than nature refills them, and non-renewable resources (oil, coal) are finite. We must not destroy tomorrow’s resources for today’s comfort.

What’s Next

You now know that development is about much more than money — it is about people’s lives, fairness and the future. But to make a country develop, we have to understand how a country actually earns its living. Where does all that income come from? Who grows our food, who makes our goods, and who provides services like teaching, banking and transport?

That is exactly what Chapter 2: Sectors of the Indian Economy explores. You will learn how every activity in the economy fits into one of three sectors — the primary sector (farming, mining), the secondary sector (factories, manufacturing) and the tertiary sector (services). You will see how India’s economy has changed over time, why so many people are still stuck in low-paying farm work, and how schemes like MGNREGA try to create jobs. It connects directly to this chapter: once you know how a country earns, you understand how its development — and its problems — really take shape.
