Median age at first marriage South Korea 1990-2023, by gender

In 2023, the median age at which South Korean women got married for the first time was 31.45 years, while that of men was 33.97 years. The average age of both men and women marrying for the first time in South Korea has risen steadily in recent years, reaching an all-time high in 2023.

Changing perceptions of marriage

The number of marriages in South Korea has been steadily declining. Although the overall decrease in population may contribute to this, the most significant factor is the societal shift in the perception of marriage. According to a survey, almost half of South Koreans view marriage as an option rather than a necessity. One of the main reasons why South Koreans choose to remain unmarried is the concern about raising children after marriage, high wedding expenses, and worries about one's career.

Demographic aspects

As an increasing number of South Koreans opt to marry later in life or not at all, this trend is significantly impacting the country's demographic landscape. The declining birth rates and rising life expectancy present challenges for the country's future, particularly in terms of economic productivity and growth.
