13 to 15 times median household income for a Seoul apartment, plus 27 trillion won a year in private tutoring fees on top of it. Jeonse was built as a financing tool to help landlords in a capital scarce economy, and hagwons were built to help students catch up on schoolwork. Together, though, they now function as two sequential entry fees for parenthood, charged during the same fifteen year window of a person's life. Korea's fertility rate sits at 0.75 not because couples have given up on children, but because most households cannot clear both fees at once. So are these two separate problems or one combined problem? What follows makes the case that they are one.
The apartment and the hagwon aren't competing for blame. They're the same problem wearing two outfits, and treating them as independent policy targets is why a decade of subsidies has barely moved the needle.

Start with Seoul, because Seoul is where the fertility numbers are worst and the housing numbers are wildest. Apartment prices in Seoul's most desirable districts, the so called Gangnam belt plus Mapo and Yongsan, decoupled from wage growth sometime around 2015 and never reconnected. A typical Seoul apartment now runs somewhere in the range of 13 to 15 times median household income. That ratio would be called a housing bubble anywhere else. In Korea it's just the price of admission to adult life.
Here's the part that gets lost in translation for outside observers. In most OECD countries, renting is a normal, stable long term arrangement. In Korea, the dominant rental system is jeonse, where a tenant hands the landlord a lump sum deposit, often 60 to 80 percent of the unit's value, interest free, for two years, then gets it back. Jeonse was designed as a financing tool for landlords in a capital scarce economy. What it actually does today is force young couples to treat homeownership as a precondition for family formation, because renting under jeonse still means locking up a sum of capital most newly married couples in their late twenties don't have without parental help.
That parental help, incidentally, is its own quiet driver of inequality. Households where parents can front a jeonse deposit or a down payment have children earlier and more often. Households where they can't are delaying marriage into their mid thirties, which mechanically compresses the childbearing window. The Bank of Korea has flagged housing cost as one of the largest measurable drags on the fertility rate in its own research, alongside labour market dualism. Seoul's fertility rate sits below the national average even though Seoul households have higher average income. Income isn't the constraint. Asset access is: a 13 to 15 times income ratio prices out most households no matter how much they earn in a given year.
Once A Couple Clears Housing, Does Private Tutoring Explain The Rest Of The Gap?
Seoul vs. Korea: Income, Housing, and Fertility Compared
| Metric | Seoul | National Average |
|---|---|---|
| Household Income | Higher | Baseline |
| Apartment Price to Income Ratio | 13 to 15x | Lower |
| Jeonse Deposit Required | 60 to 80% of unit value | Common practice |
| Fertility Rate | Below average | 0.75 |

Say a couple clears the housing hurdle described above. The next number waiting for them is hagwon spending, and it isn't optional in the way the phrase "private tutoring" implies to a Western reader. Statistics Korea's private education expenditure survey has shown total household spending on hagwons and tutoring exceeding 27 trillion won annually in recent years, spread across a shrinking pool of school age children. The intensity per child keeps climbing even as the birth cohort keeps shrinking.
That's the counterintuitive part worth sitting with. Fewer children should mean less aggregate tutoring spend. Instead, each additional won of household income above a certain threshold gets funneled into tutoring at a higher marginal rate, because the competition isn't against some fixed academic bar. It's positional. Parents aren't trying to get their child to a good score. They're trying to get their child ahead of everyone else's child, and everyone else is spending too, so the bar keeps rising for all participants at once. Economists call this an arms race dynamic. Korean parents call it Tuesday.
Companies have built enormous businesses on exactly this psychology. Megastudy and Chunjae Education built national businesses monetizing college entrance exam anxiety, and the test prep sector has proven remarkably resistant to government attempts to cap or regulate hagwon hours and pricing, dating back to crackdowns under multiple administrations since the 1980s. Regulation targets supply. It never touches the demand driver, which is that a single elite university acceptance still functions as the primary sorting mechanism for lifetime income in Korea's labour market. Hagwon spending isn't a bubble waiting to pop. It's a fixed cost of participating in the economy, priced into family planning the same way a mortgage payment is: roughly 27 trillion won a year, nationally, and rising per child.
What Happens When Housing And Education Costs Compound On Top Of Each Other?

The housing burden from the first section and the tutoring burden from the second don't simply add up. They compound. A household deciding whether to have a second child isn't asking whether it can afford a bigger jeonse deposit, and separately, whether it can afford another set of hagwon fees. It's asking whether it can afford both at once, for roughly two decades, while both cost categories keep rising faster than wages.
Consider the timeline. A couple buys or leases housing in their early thirties, right as the jeonse or mortgage burden peaks. Their first child hits the intensive hagwon years, roughly ages ten through eighteen, right as that same couple is in peak earning but also peak housing cost years. There's no point in the life cycle where the two burdens ease at the same time. They stack. Compare this to Japan, where housing costs are comparatively flat outside central Tokyo and education spending, while present, doesn't carry the same all or nothing university sorting intensity. Korea built two separate high stakes filters and stacked them on the same fifteen year window of a person's life.
The result shows up cleanly in the data on birth order. Korea's first child birth rate has held up noticeably better than its second and third child rates, which have collapsed even faster than the headline number suggests. Families are increasingly making a single child bet, treating parenthood almost like a limited allocation of capital into one asset rather than a diversified portfolio. One is manageable. Two means running both cost stacks twice, and for most households outside the top income quintile, the math doesn't clear.
Given That Compounding Effect, Can Policy Actually Reach Either Lever?
Seoul hasn't been passive here. Cash incentives, expanded parental leave, subsidized childcare, and direct housing programs for newlyweds have all expanded meaningfully since 2022, and total government fertility related spending has climbed into the tens of trillions of won annually. The 2025 uptick in the fertility rate, small as it was, gave policymakers their first genuine talking point in years.
Look at what the successful programs actually target. Housing programs offering discounted mortgage rates or priority access to newlywed apartments work because they attack the asset access problem directly, not the income problem. That distinction matters. A cash bonus of a few million won does nothing against a housing gap measured in hundreds of millions. A guaranteed mortgage rate or a subsidized long term lease, on the other hand, changes the actual constraint.
Education is the harder lever, because the government doesn't control the thing parents are actually buying, which is relative rank. It can cap hagwon operating hours. It can't cap parental anxiety about whether their child gets into Seoul National University, Korea University, or Yonsei, the so called SKY tier that still functions as a rough proxy for future earnings. Until the labour market itself becomes less winner take all, meaning until wage gaps between large conglomerate employers like Samsung or SK and the broader small and mid sized enterprise sector narrow, hagwon demand will keep regenerating no matter what regulation targets its supply side.
Korea has effectively built a system where every exit ramp from the fertility trap points toward the same destination: reducing the stakes of the sorting mechanisms themselves, in both housing and education, rather than subsidizing households to endure them. That reframe has only started entering policy conversations seriously in the past two or three years. So, back to the question at the start: is it one problem or two? It's one, a single sorting mechanism split across two life stages, and policy that treats them separately will keep producing the same 0.75.
