In South Korea, marriage and divorce can no longer be explained by personal love or temperament alone. Housing costs, job insecurity, shifting gender roles, the burdens of childbirth and child-rearing, and a growing emphasis on personal happiness are combining to change what marriage means and what families look like.
In recent years the number of marriages has risen for three consecutive years, while the number of divorces has fallen for six consecutive years. But these figures alone do not show that “marriage is back” or that “marriages have become more stable.” Both indicators are shaped by population structure and by delayed effects from the COVID-19 period. Divorce, too, should be examined not merely as the failure of a relationship but through the lenses of economic independence, child-rearing, gender equality, and life in old age.
This article draws on marriage and divorce statistics from the Ministry of Data and Statistics (formerly Statistics Korea), social survey results, and data on single-person households to examine how marriage and divorce in Korea are changing and what those changes mean for society. Facts confirmed by the statistics are kept distinct from the author’s interpretation.
1. What the Latest Statistics Show
Key findings from the 2025 Marriage and Divorce Statistics, released by the Ministry of Data and Statistics in March 2026:
- Marriages: 240,326, up 8.1% from the previous year. This is the third consecutive annual increase, following +1.0% in 2023 and +14.8% in 2024, and the highest figure since 2018 (about 258,000). It also exceeds 2019 (about 239,000), meaning marriages have returned to pre-pandemic levels. The crude marriage rate is 4.7 per 1,000 people.
- Divorces: About 88,000, down 3.3% from the previous year. This is the sixth consecutive annual decline and the lowest number since 1996. The crude divorce rate is 1.7 per 1,000 people.
- Average age at first marriage: 33.9 for men (unchanged from the previous year) and 31.6 for women (up 0.1 year). The gap between the sexes, 2.2 years, is the smallest on record.
Two factors are cited behind the rise in marriages. One is a larger population in the early-30s age group; the other is that marriages postponed during COVID-19 were concentrated in 2023–2025. In other words, the recent rebound combines structural and temporary factors, and whether it continues needs to be watched separately.
The decline in divorces should be read in the same context. The Ministry explains that the long-term shrinking of the number of marriages is a major influence. Because divorces occur among people who married in earlier years, divorce counts tend to fall after a period in which marriages declined. It is therefore difficult to interpret the drop in divorces directly as an improvement in marital relationships.
Nor should the number of marriages and the number of divorces in the same year be compared directly to conclude that a certain share of married couples divorce. Marriages and divorces in the same year involve people who married at different times.
2. Marriage Is Shifting from Necessity to Choice
For a long time in Korea, marriage was regarded as a stage of life one naturally passed through on becoming an adult: get a job, marry, have children, and form a family.
Today, however, marriage is increasingly seen as something to be decided for oneself. Personal happiness and freedom, economic security, career development, and emotional fulfillment have all grown in importance.
The Statistics Korea 2024 Social Survey shows that this change is not one-directional.
- 52.5% of respondents said one should marry, up 2.5 percentage points from 50.0% in 2022. A majority still holds this view, and it has risen slightly in recent years.
- 67.4%† said it is acceptable to live together without marrying, and 37.2%† said it is acceptable to have children without marrying.
This does not mean society has turned against marriage itself. Rather, it shows a growing view that marriage, cohabitation, childbearing, and personal independence need not be bundled into a single path. The Ministry also cited a more positive attitude toward marriage among unmarried men and women as one factor behind the rise in marriages.
For those who choose marriage, a stable partnership and family formation may matter most; for those who do not, economic independence and sustaining their own way of life may matter more. The important change is therefore not the disappearance of marriage but its settling in as one of several life choices.
3. Economic Conditions That Make Marriage Harder
Explaining why people postpone or forgo marriage purely in terms of personal values overlooks important social causes. Housing costs, wedding funds, job security, and worries about future living expenses strongly influence the decision to marry. This section is closer to sociological interpretation than to statistical fact, and the influence of each factor needs to be confirmed through separate surveys.
Housing Costs and Wedding Funds
When preparing for marriage, buying a home or paying a lease deposit can be a major financial burden. Young adults whose income is limited, or who have had little time to accumulate assets, must plan for life after marriage and may therefore delay it.
That starting lines differ depending on parental financial support is also a social problem. Family assets and economic background, not just individual effort, can affect whether marriage is feasible.
Job Insecurity and Uncertainty About the Future
A stable job and income are important for planning married life. When employment is delayed or precarious, it is hard to plan for housing and living expenses.
When childbirth is also considered, the burden grows, since one must account not only for child-rearing costs but also for lost income during parental leave, career interruption, and the cost of childcare services.
Ultimately, the postponement of marriage may reflect declining interest in marriage, but it is also linked to people who want to marry yet delay because the practical conditions are not in place. Given that the recent rise in marriages rests partly on population structure and delayed effects, it is uncertain whether the increase will continue if these economic conditions do not improve.
4. Changing Gender Roles and Conflict in Married Life
In Korea, women’s educational attainment and labor-force participation have expanded, and dual-income households have become an important family type. The marriage statistics also show change.
- The gap in average age at first marriage between the sexes is 2.2 years, the smallest on record.
- Among first-marriage couples, the share in which the wife is older reached 20.2%, exceeding 20% for the first time. The share in which the husband is older is 63.0%, still the highest but down 0.4 percentage points from the previous year; couples of the same age account for 16.7%.
Yet changes in economic activity and marriage patterns are not automatically reflected in how housework and child-rearing are divided. Even when both spouses work, housework and child-rearing can fall mostly on one of them. One partner may then feel a double burden at work and at home, while the other, accustomed to traditional gender roles, may not even recognize the conflict.
Such problems arise not only from differences in personality but from a mismatch between the roles society expects and actual living conditions. To keep a marriage stable, couples need to discuss together economic responsibility, housework, child-rearing, and care for both sets of parents. It is especially important to check concrete expectations about money management, plans for children, support of parents, and career continuity before marriage.
The stability of a marriage is not determined by the size of love alone. Whether partners can reconcile differing expectations and share everyday responsibilities fairly also matters.
5. Why Is Divorce So Difficult? Property, Children, and Social Attitudes
Divorce is a decision to end a marital relationship, but in reality it is a process of reorganizing many areas of life at once.
First, there are the division of property and economic independence. Homes, loans, savings, and pensions must be settled, and a spouse with low income, or one who long handled housework and child-rearing, may worry about living expenses and housing after divorce.
Second, couples with children must consider custody, child support, visitation, residence, and the educational environment. The effect of marital conflict on children is also an important concern.
Third, there are social attitudes toward divorce and emotional burdens. Reactions from parents and relatives, the judgment of those around them, and a sense of responsibility for the years spent together can make it hard to end a relationship.
These factors mean divorce cannot be treated as a matter of individual will alone. How well-prepared a person can be for life after divorce depends greatly on access to economic self-sufficiency, housing support, child-rearing support, and legal information.
That said, avoiding divorce at all costs is not necessarily desirable either. Where a relationship can be repaired, counseling and dialogue may be considered, but where violence or coercive control exists, securing safety comes first.
6. How Should We Read “Late-Life Divorce”?
In the 2025 marriage and divorce statistics, divorces after 30 or more years of marriage accounted for 17.7% of all divorces, the largest share by duration of marriage. However, the gaps with 5–9 years (17.3%) and 4 years or less (16.3%) are small, so this figure alone does not justify asserting that late-life divorce has surged.
Looking at age-specific indicators makes the picture clearer.
- Counts: Divorces among people aged 60 and over are the most numerous: 20,400 for men and 14,600 for women. This partly reflects the large size of the older population itself.
- Rates: Divorce rates relative to population are highest for men aged 45–49 (7.0) and women aged 40–44 (7.7).
- Average age at divorce: 51.0 for men and 47.7 for women, each up 0.6 year from the previous year and more than four years higher than a decade ago.
In other words, divorce is concentrated among older people in absolute numbers, but the likelihood of divorce (the divorce rate) is highest in middle age. It is also clear that the timing of divorce is rising overall.
In the past, some couples may have stayed married despite dissatisfaction because of child-rearing, economic dependence, and social expectations of the family. As life expectancy lengthens and expectations for one’s own life change, some people may also think anew about life after their children become independent. Retirement lifestyle, economic independence, long-accumulated conflict, and emotional distance from a spouse are factors that long-married couples may weigh when reassessing the relationship.
However, the share by duration of marriage or the counts by age cannot by themselves establish the causes of late-life divorce. Understanding them properly requires analyzing age, duration of marriage, economic conditions, and the presence of children together. It is also worth remembering that the length of a marriage alone is a poor measure of a couple’s satisfaction or success.
7. The Rise of Single-Person Households and Changing Family Forms
Another indicator of family change in Korea is the growth of single-person households. In 2024, single-person households were tallied at about 8.05 million, 36.1% of all ordinary households†.
The reasons for this increase are varied: young adults becoming independent, living apart because of work or study, lifestyles that do not involve marriage, divorce and bereavement, and population aging all play a part. The rise should therefore not be equated directly with avoidance of marriage. Even so, it shows that Korean society is no longer made up solely of the traditional family of a couple and children.
As family forms diversify, policies on housing support, elder care, child care, and the prevention of social isolation become more important. Support for stable living should not be limited to those who marry; it should create an environment in which people can live independently and receive the care they need regardless of marital status.
8. How Are Low Fertility and Marriage Connected?
In understanding Korea’s low fertility, the relationship between marriage and childbirth matters. Because childbirth in Korea is strongly tied to marriage, later marriage or fewer people marrying can affect births as well. But childbirth is shaped not only by marital status but by housing stability, child-rearing costs, working hours, the care environment, and personal intentions about having children.
The recent increase in marriages may be a positive signal for future birth statistics. However, since the rise in marriages owes much to population structure and delayed effects, whether it leads to more births needs to be confirmed separately through birth data.
This is also why policies that merely encourage marriage can hardly solve low fertility. Even if people want to marry and have children, their wishes may not turn into actual choices if housing and child-rearing costs are too burdensome, if it is hard to keep one’s career after giving birth, or if there is too little environment for sharing care. A response to low fertility should therefore look beyond increasing the number of marriages and consider housing stability, quality jobs, work–family balance, public care, and an equal division of housework.
9. Challenges for Korean Society
Changes in marriage and divorce arise from the interplay of individual choices and social structure. Several directions should be considered together.
First, strengthen young people’s housing and economic foundations. Because the recent rise in marriages owes much to growth in the early-30s population, housing stability and employment conditions need to improve so that people who want to marry do not keep postponing because of housing costs and wedding funds, even after the population effect fades.
Second, provide real support for work–family balance. Parental leave, flexible work, and care services must be genuinely usable, and structures that concentrate housework and child-rearing on one spouse must change. Couples’ role expectations are shifting, as the narrowing age gap and the growing share of older wives show.
Third, respect diverse family forms. Not only married couples with children but also single-person households, single-parent households, and unmarried households should have access to stable housing, care, and social security.
Fourth, support life after divorce. Legal information on property and child-rearing, child care, and housing and employment support can reduce the economic and social risks that arise during divorce. Because the average age at divorce is rising and divorces among older people are numerous, retirement income and housing measures are also needed.
Fifth, a social outlook that values the quality of married life is needed. Rather than treating a long marriage as the sole standard of success, we should also weigh whether the relationship is one in which both people respect each other and live safely.
Conclusion: Changes in Marriage and Divorce Are Changes in Korean Society as a Whole
Looking at Korean marriage and divorce through the statistics, several phenomena appear at once: three consecutive years of rising marriages, six consecutive years of falling divorces, a narrowing age gap at first marriage, more varied views of marriage, a growing number of single-person households, and divorce among middle-aged and older people.
However, the rise in marriages was driven largely by growth in the early-30s population and delayed effects from the COVID-19 period, and the decline in divorces is likewise influenced by the earlier decline in marriages. Reading these two indicators directly as a fundamental change in society or an improvement in marital relationships calls for caution.
These changes do not mean people have given up on marriage altogether, nor that the institution of marriage persists in the same way as before. It is more accurate to say that marriage remains an important choice but that the economic conditions and social expectations surrounding that choice are changing. Divorce, too, can hardly be explained solely as personal responsibility or relational failure; economic independence, child-rearing, gender roles, emotional fulfillment, and life in old age all interact.
The question Korean society must now consider is not only how the numbers of marriages and divorces move. People who wish to marry should be able to reduce practical burdens and build stable households, and people who do not marry or who divorce should be able to live without economic hardship or social prejudice.
What ultimately matters is neither insisting that everyone must marry nor viewing divorce as unconditionally negative. It is building the social foundations that let individuals choose their lives responsibly, and creating an environment in which people are respected whichever family form they choose.
