Why You Don't See Kids in Korea: A Travel Writer Encounters the Population Collapse

Tell someone visiting Seoul for the first time that Korea’s population is shrinking, and they probably won’t believe you. A Friday night outside Hongdae’s playground, a Saturday afternoon in the back streets of Seongsu-dong, the Line 2 transfer tunnel at rush hour — everywhere you look, the city is heaving with people.

But go to a neighborhood market on a weekday around eleven in the morning, and the story starts to shift. The vendors perched on plastic stools, the shoppers with their canvas carts — most look north of sixty. Strollers are rare. Walk past an apartment complex playground and you will spot seniors dangling from the exercise equipment where children used to climb. Head out to the provinces and it gets even clearer. That charming café with the big windows and high ceilings and the schoolyard-turned-parking-lot — it was a school once. A school that closed because the children vanished.

The numbers go like this.

From 6 to 0.8 in Six Decades

A generation ago, the Korean government had the exact opposite problem: the population was growing too fast.

In the 1960s, the average Korean woman gave birth to six children over her lifetime. The government sent vans into villages to promote family planning. Slogans like “Don’t care if it’s a son or daughter — have just two and raise them well” were plastered on buses and walls. By the 1980s, the message had tightened to “Even two is too many.” The campaign worked. It worked too well.

📉 Korea's Fertility Rate Over 60 Years — How the Slogans Changed

For a population to hold steady, the total fertility rate needs to be 2.1. Korea crossed below that line in 1983 and has never come back — not once in over 40 years. What this means is that the changes unfolding now are not some sudden accident. They are the slow accumulation of four decades of mathematics finally becoming visible to the naked eye.

What Travelers Actually Encounter

Statistics are abstract. Their consequences, on the other hand, are surprisingly concrete — visible right on the street. Spend a few days moving around Korea, and you will almost certainly run into at least two or three of the six things below.

How Many Schools Have Closed?

The first thing to collapse, and the most visible, was the schools. When births drop, the dominoes take six years to hit elementary school, twelve for middle school, another six for university.

In the 2026 school year, Korea’s first-grade class numbered 298,178 children. It is the first time since records began that the incoming elementary class has fallen below 300,000. For context: in 1971 alone, 1.02 million babies were born. The number of children entering elementary school today is less than one third of that generation.

🏫 School-Age Population (6–21) Projection — Down 860,000 in 5 Years

In March 2026 alone, 32 more schools closed across the country — 26 elementary, 5 middle, and 1 high school. Seoul is not immune: by 2028, the number of elementary schools with fewer than 240 students is projected to reach 101, or 16.5% of all elementary schools in the capital.

The Fastest-Aging Country on Earth

A low birth rate means fewer young people — and, at the exact same time, a rapidly swelling share of older ones. At the end of 2024, Korea officially became a super-aged society, defined as a country where more than 20% of the population is 65 or older.

It took France more than 150 years to go from an aging society to a super-aged one. Korea did it in 25. The problem is the speed. It means society had no time to adjust.

The regional gap is widening, too. Over the past decade, the number of obstetrics and gynecology clinics in the greater Seoul area rose from 703 to 779. Outside the capital region, they fell from 601 to 554. When there is no hospital left to deliver a baby, young couples leave. When young couples leave, schools close. When schools close, the next couple never comes at all. The shuttered storefronts you see in provincial towns are usually the endpoint of that exact sequence.

But Then the Numbers Turned — Starting in 2024

This is where the story takes a small turn. After eight consecutive years of decline, the fertility rate bounced in 2024, and then rose again in 2025.

There were 254,457 births in 2025 — 16,100 more than the year before, a jump of 6.8%. That is the largest increase since 2007. In the first quarter of 2026, 75,013 babies were born, up 14.8% from the same period a year earlier — the steepest quarterly increase since records began in 1981.

Three factors are usually cited. First, marriages postponed during the pandemic came in a cluster. Second, the large cohort of people born in the 1990s are now in their early-to-mid thirties, temporarily thickening the pool of people at prime childbearing age. Third, government policies — expanded parental leave, housing support, and cash subsidies.

Most analysts lean toward the first two. If this rebound is mostly demographic structure, the bump could fade once the 1990s cohort moves into their forties in the early 2030s. The government’s optimistic scenario projects the fertility rate climbing back to 1.0 by 2031 — and the current pace is actually running ahead of that projection. Which side is right is something only the next few years can answer.

So What Kind of Country Is Korea Now?

The native-born population is shrinking year after year — and yet the total population has been growing for three years straight. The reason: people are moving in.

At the end of 2025, there were 2,783,247 foreign residents in Korea, making up 5.44% of the total population. More than 1 in 20 people living in Korea today was born somewhere else. Ten years ago, a number like that would have been hard to imagine.

Why does any of this matter to a traveler? Because Korea right now is a country deciding, in real time, what kind of country it is going to become. The tandoor ovens baking Samarkand-style bread on Dongdaemun’s Central Asian street, the Indonesian grocery stores in Ansan, the lamb-skewer alleys of Daerim-dong — none of these were built as tourist attractions. They are simply neighborhoods made by the people who live there. In the coming years, there will be more of them.

And to circle back to those closed-school cafés — the big windows, the high ceilings, the parking lot where children once ran during recess. That is not a charming interior-design concept. It is what a nation looks like when a statistical table is turned into architecture. While you drink your coffee, look for the chalkboard marks still visible on the wall, or the old classroom number plate. Usually, they leave them there.
