A few days ago, an X user named Alka Gurha posted something I think more of us should be talking about.

She ended with one line: "Is it any surprise people have only one kid?"

I think she's onto something, and the reason most people have one kid now is less about money than it looks.

That ₹2.5 lakh, for a single school trip, is more than what a child pays in fees across their entire schooling at a Kendriya Vidyalaya. 

And among the urban parents I know, this isn't all that unusual anymore.

She posted this a day after the internet had started arguing about exactly the same thing.

The day before, Elon Musk had reposted a chart about India, with his own line on top: the birth rate has fallen below replacement…

Most people read it as straightforward bad news, that India is shrinking and growing old, and the numbers suggest that’s true.

India's fertility rate is now 1.9, below the 2.1 a country needs to replace itself, confirmed by both the UN and the government's own SRS data.

But the national average masks the regional numbers, which point somewhere stranger.

Delhi is at 1.2. Kerala and Tamil Nadu, two of our richest states, are at 1.3. Bihar, the poorest, is at 2.9, with Uttar Pradesh close behind at 2.6.

So the wealthier and more educated a state is, the fewer children its families are having. The poorer the state, the more.

This is the opposite of what we're taught to expect.

We assume people have fewer children when money is tight, but here it's the families with the most money who are stopping at one.

Alka's friend, the one spending ₹2.5 lakh on a school trip, is clearly not short of money. So this was never really about money.

An economist worked out what it's about, more than sixty years ago.

In 1960, Gary Becker decided to look at the choice to have children the way economists look at any other choice.

He called it the quantity-quality tradeoff.

You can have a lot of children and give each of them a little, or have a few and give them a lot. The same money can't do both.

Having one more child isn't a fixed price. It costs you whatever you're already spending on the children you have.

If your idea of raising a child is a government school and hand-me-downs, a second child barely changes anything.

But if your idea of raising a child is a private school, coaching, a ₹19,000 shoe and a trip to Japan, then a second child means doing all of that twice.

So as our idea of what a child "deserves" goes up, the cost of each child goes up with it. 

Eventually, the standard becomes untouchable, and the only thing families can still change is how many children they have.

That's the real reason wealth pulls birth rates down. Rich families could always afford more children. The bar they themselves had set for one child was just too high to clear for two or three.

This pattern isn't peculiar to other countries.

Researchers have checked it against Indian data across several rounds of the National Family Health Survey and it holds here too.

It's strongest in our cities and you can see it in what we spend.

Last year, a government survey of 52,085 households found families paying ₹25,002 a year on a child in a private school, against ₹2,863 on a child in a government school.

Nearly nine times the cost, and that's before you add coaching, holidays, or Japan.

Then there's coaching, and about 27% of students take private tuition now. An urban family with a higher-secondary student spends close to ₹9,950 a year on it.

So this is what a "properly raised" urban child has come to mean. Private school, coaching, a device, a calendar full of trips.

At that cost, the couple who'd have had two or three children a generation ago is having one today.

First-born children are now 66.4% of all births in India and it's the second and third child who are disappearing.

Becker's idea explains Japan, Italy, South Korea, every rich country that's gone through this. But it cuts deeper here, for a reason that's very Indian.

For us, the child has always been how a family rises. One generation works hard so the next can go further. 

Here, the child is also the family's whole plan for the future.

And when the child carries that much weight, spending on them stops feeling like an economic choice and starts feeling like a duty.

If raising your child "well" comes to mean getting them ahead of everyone else's child for the same handful of good colleges and good jobs, then spending anything less than the maximum starts to feel like letting them down. 

And if you can't bring yourself to cap what you give to one child, then the number of children is the only thing that can give.

A family in rural Bihar isn't thinking this way, which is exactly why Bihar is still at 2.9. 

This pattern only starts once a family accepts the belief that a child has to be heavily invested in to have a good life.

Most urban Indian families have absorbed that belief, while large parts of rural India haven't yet.

Most people read that chart and felt worried, that India is ageing, that we'll grow old before we grow rich. 

At a policy level, that worry is fair.

But if you're thinking about your own family, there's a more useful way to read it.

What the chart is mostly capturing is a version of childhood that has gotten extremely expensive.

The 'too poor to have children' reading is a much smaller part of the story.

The question I keep coming back to is whether everything we're buying for our children is making their childhood better, or whether a lot of it just looks like it does.

A child with a Japan trip and three coaching classes isn't obviously happier than a child with a calmer home and a bit less pressure on them.

Becker measured a child's "quality" purely by the money spent on them, and he was honest that this was a shortcut. 

What shapes how a child turns out is attention, stability and time, far more than any of the things we tend to compete over.

I'm not saying anyone should have more or fewer children. I have one, and that feels exactly right for us.

Alka's friend is calculating something narrower than whether she can afford a second child.

She's calculating whether she can afford to give a second child the exact same everything as the first, which is a much more expensive thing to afford.

So let me ask you what I've been asking myself. If raising a child cost what it cost your own parents, would you have made the same choices about your family that you have, or plan to?

Until next week,
Ritesh

P.S. Becker won the Nobel in 1992, partly for this work. He spent his career arguing that even our most personal decisions have a quiet economic logic underneath them. I find that idea bleak about half the time and clarifying the other half.
