Why Are Korean Marriage and Birth Rates So Low?

Written by a Korean-born writer who spent three decades in the airline industry, sharing what growing up in Korea actually looks like.

Introduction: The Country That Stopped Having Children

Korea's total fertility rate in 2023 was 0.72. If that number doesn't immediately land, here's a frame of reference: a country needs a fertility rate of at least 2.1 to maintain its population without immigration.

Korea isn't even close to half of that. Among OECD member countries, it sits at the very bottom, by a significant margin.

There have been reports in recent months of a slight uptick in the birth rate, but the numbers aren't yet large enough to call it a meaningful shift. Most analysts are treating it as a possible blip rather than a reversal.

In short: Korea's record-low birth rate isn't caused by any single factor — it's the combined weight of unaffordable housing, unstable jobs, brutal education costs, and shifting gender expectations, all landing on one generation at once.

When I got married in the early 1990s, it was taken for granted that a couple would have at least two children. My own mother's generation said you needed at least three, or the children would be lonely.

Getting from that world to a fertility rate of 0.72 has taken less than two generations. That compression is part of what makes this so hard to understand from the outside.

This article is an attempt to explain the "why" honestly. Not with simple answers, because there aren't any.

How Korea Got Here: Historical and Cultural Background

The Price of Compressed Growth

Korea was one of the poorest countries in the world in the 1960s, with a per capita GDP lower than Ghana's at the time. Within a single generation, it became a global exporter of semiconductors, automobiles, and cultural content.

That transformation was built on extraordinary competition. The drive toward better schools, better jobs, and better apartments became embedded in Korean society at a structural level.

That competitive drive passed directly to the next generation. Korean parents carry a near-compulsive belief that their children must attend a good university, and that belief produced the hagwon (학원) culture, a private academy industry of enormous scale.

The cost of educating a single child in Korea has reached a level many families experience as financially overwhelming. Increasingly, having a child feels less like a natural next step and more like a financial risk.

Housing Costs That Price Young People Out

To understand why young Koreans feel they can't afford to start a family, the housing numbers need to be made concrete. A standard three-bedroom apartment in Seoul, roughly 85 to 100 square meters, currently sells for between 800 million and 2.5 billion Korean won, approximately $600,000 to $1.8 million USD.

For context, that's comparable to buying in Manhattan or central London, in a city where the median monthly salary is around $2,500 USD. The math doesn't work for most people in their twenties and thirties, no matter how carefully they save.

A young couple starting out after marriage is unlikely to be buying anything. What they're looking at instead is a rental system with its own particular pressures.

Korea has a unique rental arrangement called jeonse (전세), in which a tenant pays a large lump-sum deposit, often 50 to 80 percent of the property's value, instead of monthly rent. For many young Koreans, assembling a jeonse deposit has become the first major financial obstacle to forming a household, well before children even enter the conversation.

This same housing math is a major thread in why so many unmarried Korean adults still live with their parents well into their thirties — explored in more detail in another piece on this blog.

Unstable Employment

Housing is only one part of the picture. Korea's job market has grown increasingly stratified, with a clear line between stable full-time employment at a large company or in the public sector, and the precarious contract work many young Koreans cycle through for years.

Marriage and children require a long-term financial horizon. That horizon is genuinely difficult to see when your employment status is uncertain.

Gender Tension and Changing Expectations

This part of the picture is the most sensitive, and it touches the fertility question most directly. Korean women's educational attainment and labor force participation have risen sharply over recent decades, but the structural expectations placed on women within marriage haven't changed at the same pace.

The gender wage gap in Korea remains among the widest in the OECD. The expectation that women carry the primary burden of childcare and housework, even in dual-income households, is still widespread, and involuntary career interruption after childbirth remains a documented pattern.

Many Korean women have concluded, not unreasonably, that marriage and childbirth come at a disproportionate personal cost to them specifically. At the same time, many Korean men carry their own pressures: mandatory military service that removes roughly two years from the early career, the expectation to be the primary financial provider, and the cost of marriage itself.

Both sets of frustrations are real, and both have sharpened a gender conflict among younger Koreans that's visibly more intense than in peer countries. How much of this drives the fertility decline directly is genuinely hard to isolate, but it can't be left out of the explanation.

What This Looks Like in Practice Today

The Sampo Generation and What It Replaced

Korea has a phrase that emerged around the early 2010s: sampo sedae (삼포 세대), the "three give-up generation," referring to giving up on dating, marriage, and children. The number expanded over time: five give-ups, adding homeownership and social relationships, then seven, and eventually N-po, where N stands for an uncountable number of things being abandoned.

This language entering common use more than a decade ago matters. This isn't a sudden crisis — it's been building quietly for a long time.

A thirty-year-old with a stable job in Seoul, after rent, student loans, and basic living costs, often has no realistic path to saving enough to marry on any normal timeline. This isn't individual failure. It's a structural outcome landing on a very large number of people at once.

What a Wedding Costs in Korea

The cost of getting married in Korea is itself a significant barrier. A standard Korean wedding involves a dedicated wedding hall, professional photography and videography, the bride's dress and groom's suit, hair and makeup packages (commonly called seu-deu-me, short for studio, dress, makeup), household goods, and a honeymoon.

Total costs regularly run into tens of millions of won, sometimes well over 50 million won ($35,000 USD or more), for a couple that may have only recently started earning a stable income.

Smaller weddings and simple registration-only arrangements have become more common among younger couples trying to reduce this burden. Family expectations from both sides, though, often push in the opposite direction.

The Weight of Education Costs

Once a child is born in Korea, educational spending begins almost immediately. English programs, math academies, and private tutoring often start before primary school.

By middle and high school, a family's monthly spending on private education can run into the hundreds of thousands of won per child, and for many families, combined hagwon and tutoring costs regularly consume more than thirty percent of household income.

Many Korean parents accept that burden willingly. But today's young couples are being asked to absorb those costs before they've had the chance to build the financial foundation that might make it manageable.

Being a "good parent" in Korea also carries social expectations around time and involvement in a child's education, expectations that are difficult to meet when both partners work full-time. The combined weight of money and time is a burden many young people look at and decide they can't take on.

Government Efforts and Where Things Stand

The Korean government has directed enormous public funding toward the birth rate, with estimates suggesting hundreds of trillions of won over the past two decades in birth incentives, childcare subsidies, and expanded public daycare.

These efforts have accompanied a continued decline in fertility, which fell from 0.78 in 2022 to 0.72 in 2023. That doesn't necessarily mean the policies were poorly designed.

It means the scale of the problem exceeds what financial transfers alone can fix. Housing costs, employment insecurity, gender inequality, and educational competition are deeply embedded, and meaningfully shifting them takes far more than subsidy programs.

A Generation Rethinking What Life Is For

Beyond the economic factors, a genuine shift in values is taking place among younger Koreans. More than previous generations, Koreans in their twenties and thirties tend to place significant weight on personal quality of life and individual autonomy.

Marriage and parenthood, in the traditional framing, require substantial sacrifice of all three. For a growing number of young Koreans, that trade-off no longer feels self-evidently worth making.

This isn't selfishness. It reflects the fact that the social contract that made that trade-off obvious to previous generations, a stable job, an affordable home, a predictable future, has become harder to access.

Common Misunderstandings

• ❌ Myth: Young Koreans are giving up on marriage and kids out of indifference or selfishness.
• ⭕ Reality: Most are making a hard financial calculation — the math genuinely doesn't work on a normal timeline for a large share of them.
• ❌ Myth: Government cash incentives just haven't been generous enough yet.
• ⭕ Reality: Korea has already spent hundreds of trillions of won on this, and the rate kept falling — the underlying structural costs run deeper than subsidies can reach.
• ❌ Myth: This is mainly a women's issue, or mainly a men's issue.
• ⭕ Reality: Both genders carry real, distinct pressures — the wage gap and childcare burden on one side, military service and provider expectations on the other — and both feed the same outcome.

What Koreans Actually Say

The lines below aren't direct quotes from real interviews — they're representative of the kind of language Koreans commonly use in these situations.

Foreigner: "Why don't more young Koreans want kids?" Korean: "It's not that we don't want them. We just don't see how we'd afford it." (thinking: I've actually run the numbers, more than once.)

Foreigner: "Would things change if housing got cheaper?" Korean: "That would help a lot, but honestly, the wedding alone already scares people off."

Foreigner: "Do your parents pressure you about this?" Korean: "Constantly. But pressure doesn't pay my rent."

For Foreign Visitors: Understanding This in Conversation

Bringing It Up With Korean Friends or Colleagues

Asking a Korean colleague or friend "why don't Koreans get married?" or "why aren't people having children?" can feel more personal than the asker intends. Many younger Koreans are navigating this pressure directly, from family, from their social environment, and sometimes from within themselves.

A more natural way in is through specifics: asking how housing works in Korea, what the job market looks like for young people, or what a typical Korean wedding involves. These lead toward the larger picture without putting anyone on the defensive.

An Observation Worth Noting

One pattern worth noting: foreign-Korean couples appear, on average, to have more children than typical Korean-Korean couples. Wherever a family takes root in Korea and chooses to raise children here, that contributes something the society genuinely needs right now.

Conclusion: One Explanation Is Never Enough

Korea's low fertility rate isn't the result of any single cause, and it won't be solved by any single policy. That's precisely what makes it so difficult.

Plenty of Koreans in stable jobs still say they want two children once they marry. But that same stability is exactly what makes those plans easy to say out loud in the first place, and it's exactly what a large share of their peers don't have.

My own reading of this is that it's tempting to treat this as a temporary disruption, a side effect of the extraordinary transition from extreme poverty to advanced industrial society that Korea made in a single generation. But enough demographers and sociologists argue it runs deeper than that to make dismissing it too quickly feel dishonest.

The number 0.72 represents a demographic reality. Behind it are millions of individual Koreans, not refusing family life out of apathy, but looking at the conditions available to them and calculating that they can't manage it right now.

Before asking why Koreans aren't having children, it's worth asking a different question: if you were in their position, what would you decide?
