Why Young South Koreans Delay Marriage

Many young South Koreans delay marriage because marrying in Korea is treated as founding a whole new household at once: housing, stable income and an agreement about who absorbs the care work. Others opt out entirely, which is a separate decision with separate reasons. The annual number of marriages has in fact risen for three straight years, so the honest question is not whether Koreans still marry but why the age at which they do keeps climbing, and who pays the cost of getting ready.

Are fewer South Koreans actually getting married?

Not at the moment. Marriages rose 8.1 percent in 2025 to roughly 240,000, a seven-year high and a third consecutive annual increase, according to Marriage and Divorce Statistics in 2025 from the Ministry of Data and Statistics, the agency formerly known in English as Statistics Korea. The total finally passed the 239,200 recorded in 2019, the increase was led by people in their early thirties, and 82 percent were first marriages for both partners.

One number did not improve. The mean age at first marriage stayed at 33.9 for men and 31.6 for women, against 32.6 and 30.0 ten years earlier. The count is recovering while the threshold moves later. Officials read the rebound cautiously, crediting a larger cohort in its early thirties, weddings postponed during COVID-19 and more positive attitudes among single people.

One technical point matters here. Korean statistics count 혼인신고 (honin singo), the registration of a marriage at a local government office. The ceremony has no legal effect on its own, and couples living together without registering never appear. The statistic tracks a legal act, not a relationship.

Why does marriage in Korea mean forming an entire household at once?

Because the unit Korean institutions recognise is the 가구 (gagu), the household: a separate address with its own tenancy or title, its own debt and its own administrative record. Housing programs, tax rules and family policy are organised around it, so a couple that marries is expected to have already solved the housing problem rather than to solve it gradually.

Korean housing makes that expensive up front. Under 전세 (jeonse), the dominant lease form, a tenant hands the landlord a lump-sum deposit worth a large share of the property’s value, pays little or no monthly rent, and gets the deposit back at the end of the term. It is cheap month to month and brutal at the start, because it demands capital rather than cash flow. A couple can have two salaries and still not have a jeonse deposit, which is why parental help and bank loans do so much of the work here. For related context, see how Korea’s apartment and jeonse systems influence housing decisions.

How much debt do Korean newlyweds start with?

A lot, and more each year. The government’s 신혼부부 (sinhonbubu) statistics define a newlywed couple as one within five years of a first marriage registration, the same definition used for program eligibility. In the 2024 Newlywed Couples Statistics, 42.7 percent of such couples owned a home, 59.7 percent were dual-income and 86.9 percent carried outstanding loans.

The size of those loans is the story. Among borrowers, the median outstanding balance reached 179 million won in 2024, up 130.1 percent from 77.78 million won in 2016, and the share owing 300 million won or more rose from 5.3 percent to 24 percent over those eight years. Owning a home does not mean escaping debt: homeowners’ median balance was 228.24 million won, against 141.6 million won for couples without one. Seoul is its own category. About 65.9 percent of newlywed couples there own no home, and among those who do, 31.4 percent hold homes assessed above 600 million won, up from 5.9 percent in 2015, against 9.3 percent nationwide. Seoul’s pull on jobs and schools is part of that price, as covered in why everything concentrates in Seoul.

What reasons do unmarried Koreans give for not marrying?

Money first, then care, then job security. In Statistics Korea’s 2024 Social Survey, unmarried respondents named a lack of funds most often at 31.3 percent, followed by the burden of childbirth and childrearing at 15.4 percent, unstable employment at 12.9 percent and no felt need to marry at 11.3 percent, as reported by the Korea Herald. These are stated reasons from one survey population, not a measured causal ranking, and they should not be rewritten as the view of all young Koreans or of one gender. Attitudes are split rather than hostile: 52.5 percent still said people should marry, while acceptance of couples living together without marrying reached 67.4 percent, up from 46.6 percent in 2014.

Why do Korean men and women answer marriage questions so differently?

Because they are often pricing different contracts. Men were considerably more likely to cite insufficient funds, 38 percent against 25 percent of women, while women more often cited the childbirth and childrearing burden, 14.4 percent against 11 percent. On marriage in principle, 58.3 percent of men said people should marry against 46.8 percent of women, and among unmarried respondents the gap widened to 41.6 and 26 percent.

The gap becomes legible next to the division of unpaid work. In the same survey, 68.9 percent said housework should be shared equally between spouses, while only about 24 percent of husbands and 23 percent of wives said it actually was. Opinions have moved faster than household practice, which makes the decisive questions concrete rather than ideological: who leaves work early when a child is sick, whose career absorbs a relocation, who decides if the two incomes diverge. Where those answers are undecided, marriage reads as a long commitment with one clause left unpriced.

What is the Korean government doing about it?

Mostly lowering the entry cost of the household. Korea.net’s summary of newlywed support describes three mechanisms: a reserved quota for newlyweds inside the 특별공급 (teukbyeol gongeup) special-supply track of the apartment subscription lottery, which matters because the ordinary lottery awards points for age and years of saving that young applicants cannot have; public rental programs such as Happy Housing and Newlywed Hope Town; and state-backed loans at below-market rates, 디딤돌 (Didimdol) for purchases and 버팀목 (Beotimmok) for jeonse deposits, with preferential terms for newlyweds.

Cash is the newer policy lever. The marriage income-tax credit is scheduled to end after 2026. In September 2026, the government proposed in its 2027 budget a direct cash payment of 1 million won per newly married couple to replace that credit. As of October 2026, this was a proposed program, not an entitlement already in effect: final implementation, eligibility and payment procedures depend on the approved budget and subsequent rules. The reason for switching from a tax credit to direct support is that a credit is less useful to people with little taxable income; the government has also described the shift toward budget-based support. Eligibility for foreign residents should not be assumed before official rules are published. Separately, some local governments run their own marriage-related grants, including programs discussed in reporting on regional incentives; availability and conditions differ by locality.

What is genuinely contested here?

Four things, and they are worth separating.

Whether the rebound is structural. Officials point to cohort size and postponed pandemic weddings. No decomposition of those factors has been published, so crediting any single policy with the rise is unsupported.

Whether this is delay or retreat. Rising annual counts support delay. A climbing mean age at first marriage, plus a large minority calling marriage optional, support a longer-run shift in the institution. Both readings use the same data.

Whether non-marriage is a choice or a constraint. The evidence contains both. Somebody who never wanted to marry has not been thwarted, and somebody who gave up on an unaffordable deposit has not expressed a preference.

Whether cash works. A Seoul National University economist quoted by the Korea Times argued that what matters is an environment where work and family can coexist and housing pressure eases, while one local official asked whether anyone would marry for a congratulatory payment.

There is another way to interpret the high threshold. Some couples postpone registration until they have arranged housing and finances, while others marry with substantial debt or without home ownership. The newlywed statistics cited above show why neither experience should stand in for all Korean marriages. As housing prices rise, financial and family support can affect when people feel able to begin.

How to read the marriage trend without being misled

Three separate indicators answer three different questions. The annual count of registered marriages shows how many couples completed a legal registration in a year; it can rise when a larger age cohort reaches marriage age or delayed weddings take place. The average age at first marriage describes timing among those who married, not the share of a generation that will eventually marry. And a survey of unmarried people’s attitudes reports what respondents say, not what their future behavior must be. Treating these as interchangeable can create the false impression that either the marriage rebound or the long-run shift toward later marriage must be imaginary.

The 2025 official marriage statistics show a rebound in registrations alongside persistently high first-marriage ages. A stronger claim about whether an entire birth cohort is permanently opting out requires following people over time; a single year’s wedding total cannot settle it.

FAQ

Is marriage declining in South Korea right now?

No. Marriages rose 8.1 percent in 2025 to about 240,000, a seven-year high and the third straight annual increase, per the Ministry of Data and Statistics. The age at first marriage has not come down, so the shift toward later marriage continues alongside the rebound.

Do Koreans still think people should get married?

Opinion is divided. In the 2024 Social Survey, 52.5 percent said people should marry, 41.5 percent called it a choice and 3.3 percent said people should not. Men were markedly more positive than women.

Does low marriage explain South Korea’s low birth rate?

It is a large part of the mechanism, because childbearing in Korea remains closely tied to marriage, but not the whole explanation. See why South Korea’s birth rate is so low.

The threshold, not the feeling

South Korea’s marriage pattern is better explained by the cost of the household it requires than by any change in how young people feel about love. The institution bundles housing, income stability and an unsettled division of care into one decision, and the annual count can rise while that bundle stays heavy, which is what the 2025 figures show. The question worth asking is what a couple believes they must assemble before they are allowed to feel ready, and who carries the cost.
