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

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

Shifting attitudes towards marriage

The number of marriages in South Korea has been consistently declining. While the overall decrease in population may play a role, the most significant factor is the societal shift in the perception of marriage. According to a survey, nearly half of South Koreans consider marriage an option rather than a necessity. Some of the main reasons South Koreans choose to remain unmarried include concerns about raising children, high wedding expenses, and worries about their careers.

Demographic implications 

As more South Koreans choose to marry later in life or not at all, this trend is having a significant impact on the country's demographic landscape. Declining birth rates and increasing life expectancy present challenges for the nation's future, particularly concerning economic productivity and growth.
