Argentina’s Births Fell 46%. The Clock Is Already Running.

The Stork Took the Early Retirement Package: Argentina Has Ten Years on the Clock, and So Does Half the Planet

Alfonso Cuarón set Children of Men in 2027.

Check the calendar on your phone. Go on, I’ll wait.

That’s next year.

In the film nobody has been born for eighteen years, and it opens on a crowd pressed against a café television, weeping like they’ve lost a pope, because the youngest human being on Earth has just been killed. He was eighteen. His name was Diego. And the actor who played him, Juan Gabriel Yacuzzi, was born in Buenos Aires and cut his teeth on Cebollitas, the kids’ soccer show an entire Argentine generation can still hum.

So the last baby on the planet, in the most famous movie ever made about the end of babies, was cast out of this city.

I’m not saying Cuarón had a man inside. I’m saying that somewhere in a basement under the Obelisco a hooded order of statisticians lit one candle, looked at a chart twenty years early, and went yeah… him. Then they blew the candle out and billed the Ministry for the wax.

Why am I opening with a dystopia at ten in the morning on a Friday, you morbid little goblin? Because Infobae published a report this morning, and the numbers in it read like the film’s first draft.

The Number That Ruined My Cortado

Argentina registered 413,135 births in 2024.

In 2015 it registered 770,040.

That’s 46% fewer. In nine years. Roughly 357,000 babies a year who used to show up, get named after a footballer and scream through a Sunday asado, and now simply… don’t. A mid-sized city’s worth of people, cancelled at the reservation desk, every single year.

The fertility rate in the figures Infobae cites sits around 1.2 children per woman. The official 2023 number was 1.33. Either way it’s a long walk from 2.1, the rate a country needs to hold its population steady without migrants.

And then the one that made me set the cup down. In 2025, in the province of Buenos Aires, the biggest and most populous in the country, deaths outnumbered births: 134,521 to 124,290.

So before anybody starts wailing in the comments: fewer babies is not, by itself, the disaster. Some of these are babies that a fifteen-year-old in Formosa didn’t have, and the planet is better for it.

The disaster is a clock. And it’s ticking in a currency most people have never heard of.

The Inheritance Nobody Told You About

Here’s the mechanism, and stay with me, because it’s the whole post.

For about half a century Latin America lived off something economists call the demographic bonus. Birth rates fell from very high to merely high, and for a few decades that left the region with a fat middle: lots of people of working age, comparatively few kids and few retirees for each of them to feed. When every worker supports fewer dependents, income per head climbs even if nobody gets one bit more productive.

Per the report Infobae published this morning, by economist Eduardo Levy Yeyati (Di Tella, ex-chief economist of the Central Bank) and demographer Rafael Rofman (Cippec), income per head in Latin America and the Caribbean went from $3,336 in 1960 to a little over $9,000. Part of that climb was simply the shape of the population doing the work.

Think of it as an inheritance from a great-uncle nobody met. He left the region a big house full of twenty-five-year-olds. For fifty years we lived off the rent. Didn’t fix the roof, didn’t buy the lot next door, painted the front door twice and called it a renovation.

And the will has a clause.

The bonus ends when the smaller generations, the ones born after fertility dropped, reach working age, and the retirees keep piling up at the other end. After that the shape of the population stops pushing income up and, unless productivity and investment pick up the slack, starts dragging it down.

Brazil, Chile, Colombia and Costa Rica have already hit their peak. Argentina, along with Ecuador, Mexico, Panama, Peru and Uruguay, has about ten years of the bonus still growing.

Hence the headline. Nos quedan 10 años. We have ten years left.

The authors’ fix has a name, the second dividend: take some of what the good years produce and invest it in whatever raises productivity later, instead of eating it now. Savings. Training. Infrastructure. Technology. The boring stuff that never wins an election. Andrea Falcone of The Shift, quoted in the same piece, put it plainly: there is little room left to keep postponing decisions.

In Argentina. The country that has turned postponing decisions into an art form, a national sport and, on certain long weekends, a religious observance.

STOP.

This is the part where the post was supposed to stay home, order a medialuna and complain about the dollar like a local. Instead it’s getting on a plane. Economy class. Middle seat. Next to a man peeling a hard-boiled egg with his thumbnail somewhere over the Pacific.

Because none of this is an Argentine problem. Argentina is just the one doing it fastest, with the windows down and the radio up.

Meanwhile, On the Rest of the Planet

The United Nations’ 2024 World Population Prospects puts global fertility at 2.25 children per woman, down from 3.31 in 1990. More than half of all countries and territories are already below replacement. Roughly one in five sits under 1.4, a club that includes China, Italy, Spain and South Korea.

Now the postcards.

Japan. In 2025, 671,236 babies were born to Japanese nationals in Japan, the fewest since records began in 1899, and the tenth record low in a row. Fertility hit 1.14. Deaths beat births by 918,253, the nineteenth straight year in the red. At the postwar peak in 1949 the country was producing close to 2.7 million babies a year. It now makes about a quarter of that.

The detail I can’t shake: in 2024 Oji Holdings announced it would stop making baby diapers for the Japanese market and pour that capacity into adult ones. Japan’s biggest diaper maker had already reported, back in 2011, that adult diapers were outselling the baby kind.

Think about the meeting where that got decided. A conference room in Tokyo. A slide. A man with a laser pointer drawing one line going down and one going up, and the room nodding gravely, and somebody in the back quietly updating the product photography from a giggling infant to a man in his seventies holding a putter and wearing an expression of great serenity.

And that’s not even the cosmic part. The cosmic part is that the diaper is the first and last garment of a human life, and a whole economy just voted on which end of the story it would rather sell to. Somewhere a Fate with scissors looked up from the thread and said, oh, so we’re doing it in that order now.

Per the work Levy Yeyati and Rofman cite, demographic change knocked about 0.57 percentage points a year off Japan’s growth between 2000 and 2025. Every year. For a quarter century. Like a slow leak in a tire you keep meaning to get looked at.

South Korea owns the record for the lowest fertility ever measured in a modern country: 0.72 in 2023. It’s now being congratulated for a rebound, and to be fair the rebound is real, two years running, up to 0.80 in 2025, with births around 254,000. The statistics ministry credits mostly a backlog of weddings that COVID had postponed. Seoul climbed to 0.63. Deaths still outnumbered births by about 109,000.

A rebound to 0.80 is like celebrating that your house fire is now only on two floors.

And here’s the speed problem, which is the part that should actually keep a finance minister awake. In much of Europe this transition took roughly a century. Latin America, China and Korea are cramming it into a few decades.

Europe aged like a good cheese, slowly, in a cave, with a man in a beret turning it now and then. We’re aging like a banana left in a hot car.

What Happens When the Pyramid Becomes a Vase

Every school kid has seen the population pyramid. Wide base of babies at the bottom, tapering up to a little point of old folks at the top. A stable shape. You could build on it. The Egyptians did.

Stop having babies and the bottom pinches in while the top keeps swelling. The pyramid becomes a vase.

Keep going and the vase becomes an urn, which is a vase with a theological opinion. And past the urn, I’m told, the shape just becomes a single point hanging in a dark room, which Lovecraft would have called a population and the United Nations would call a projection.

That shape has a bill attached. In Argentina, thirty years ago, there were 29 people aged 65 or older for every 100 kids under fifteen. Today it’s 53, per Cadena 3’s data desk. The ratio has nearly doubled, and the kids who would fix it in 2040 are precisely the ones who didn’t get born in 2020.

Pensions, health, care, schools: every one of those systems was designed for the pyramid. None of them were built for the vase. You can see the first cracks already in the boring places. Provinces watching kindergarten enrollment drop. School buildings with an extra classroom nobody fills.

My daughter’s class has nine kids in it.

Nine. That’s not a class, that’s a baseball lineup with nobody on the bench. And the lineup is shrinking. Near us, several schools have already shut their doors, and the ones still standing absorbed the kids, like lifeboats hauling in passengers from ships nobody will officially admit sank.

That’s what the vase looks like from the sidewalk. Not a chart. A classroom with empty chairs and a principal pretending the extra desks are for “flexible learning.”

The Robots Showed Up Right on Time. Suspicious.

Disclaimer, before I say anything about machines: I build AI systems for a living. Weigh my optimism about automation the way you’d weigh a dentist’s opinion of caramel. I’m also not freaking Thomas Malthus, who spent his career worried about the exact opposite problem and was wrong in the other direction, which should humble everyone in this field and mostly doesn’t.

Here’s the optimistic case, and it has serious names on it. A study by Daron Acemoglu, David Autor, Keelan Beirne and Andrew Scott looked at international data going back to 1950 and found that lower birth rates went along with faster growth in output per working-age adult, and no obvious drop in total output. Where the young population shrank, labor-saving patents and investment in advanced tech went up. Fewer hands, so the economy grows mechanical ones. They call it, more or less, a scarcity dividend.

And look at the timing. The babies started vanishing around 2015. The machines that can write, draw, code and answer a phone started showing up around the same moment. The stork and the robot met in a parking garage, exchanged envelopes, and neither of them has been seen together since.

I’m joking. Mostly.

The less fun finding: Nicole Maestas, Kathleen Mullen and David Powell studied aging across the United States and tied it to slower productivity growth. The scarcity doesn’t automatically breed the invention. Levy Yeyati and Rofman say it flat out: the robot dividend needs financing, research and tech infrastructure, and Latin America doesn’t have any of those guaranteed.

Translation: the robots will come, but they’ll come to the countries that saved up for them. Everybody else gets the vase without the robot.

The other levers on the table are less glamorous. More women in paid work. Longer working lives for people who want them. Migration, where it’s viable.

On that last one I am, technically, the migration policy. A US-born guy living in Buenos Aires, paying into a system built for the pyramid. You’re welcome, Argentina. I’m not enough. Send more.

The Counterargument, Properly Made

Four, and I’m not going to strawman any of them.

One. Fewer births is not a catastrophe, and treating it like one has an ugly history. Every time a country panics about its birth rate, somebody in a suit eventually starts telling women what their bodies are for. Part of Argentina’s drop is teenagers who didn’t become mothers, and part is adults deciding when and whether, which is the whole point of having the choice. The doctors at Argentina’s reproductive medicine congress made the same distinction this week: the question isn’t how to make people have kids, it’s the gap between when people want them and when biology still lets them. That’s a health and information problem, not a patriotic one.

Two. Demographic projections are wrong all the time, in both directions. Korea’s rebound beat its own government’s optimistic forecast. Japan’s collapse arrived about fifteen years ahead of the official one. Anybody who tells you what fertility will be in 2045 with a straight face is selling something, possibly a book.

Three. The scarcity dividend might genuinely work. Acemoglu and company aren’t cranks. If shrinking workforces force the productivity boom that decades of policy couldn’t, this post will age like the Malthus paragraph above it.

Four. I’m a guy with a blog in Buenos Aires. I read the same reports you can read. If your pension strategy depends on me, we both have bigger problems.

Hold all four. Then hold this.

None of them touches the clock. The people who will be twenty-five in 2036 were born in 2011. The people entering the workforce over the next decade were born, or weren’t, between roughly 2005 and 2015, and the ones after them are already here or already missing. No policy, no subsidy, no viral campaign can reach backward and un-not-have a baby. The next ten years of the ratio are locked. What’s still open is what gets built during them.

What Ten Years Actually Buys

Ten years is a weird amount of time. Long enough to feel like plenty. Short enough that a single bad government, one currency crisis and a World Cup can eat the whole thing.

In ten years a country can train a generation of workers to use the tools that will make each of them count for two. It can build the savings that pay for the vase. It can make it easy for women to work and have kids, instead of making them pick. It can stop treating the over-60s as a cost center and start treating them as a workforce, for the ones who want in.

Or it can do what it did with the first fifty years of the bonus: live off the rent and paint the door.

I don’t know which one Argentina picks. Nobody does. That’s not a cop-out, it’s the only honest sentence in the economics section of any newspaper.

Rant over.

The stork is still on the bench. Cardigan buttoned wrong, mate gone cold, ticket number tucked under one wing, waiting for a window to call a number that keeps getting longer. Ten years, the economists say. Nos quedan diez años. Plenty of time.

And somewhere in a 2027 that’s starting to look less like science fiction and more like a scheduling conflict, Diego is still on the café TV, and the whole room is still crying, and not one of them saved a f@$king peso.
