SEOUL, November 26 (AJP) - The number of marriages in Korea reached the largest tally in a decade in September. The sharp rise in marriages — widely considered a leading indicator of births — has raised expectations that the recent rebound in childbirth numbers could continue in the coming months.

According to Statistics Korea's population trends for September released on Wednesday, 18,462 couples married last month, an increase of 3,005 cases from a year earlier. Marriage numbers have now grown for 18 consecutive months, reaching the highest level for September since 2015.

For the first three quarters of the year, cumulative marriages totaled 58,305, which represents an increase of 6,600 cases, or 12.8 percent, compared with the same period last year. 

Marriage counts rose across all regions, supported by a combination of factors, including an increase in the population at the typical marriage age, generally those in their 30s, and shifting social perceptions toward marriage.

The rebound in marriages, combined with ongoing growth in births since late last year, suggests that the annual number of newborns in 2025 could surpass last year's total of 238,317.

Korea recorded 22,369 births in September, which is 1,780 more births, or an 8.6 percent increase, compared with a year earlier, marking the highest September figure since 2020. Cumulative births for the year reached 191,040, reflecting a 7 percent increase year-on-year.

The total fertility rate — the expected number of children a woman will have over her lifetime — rose to 0.85 in September, an increase of 0.06 from a year earlier. The rate for the third quarter stood at 0.81, up 0.04.

The rise in births was driven largely by women in their 30s. Birth rates among mothers aged 30 to 34 increased by 2.4 percent, and those 35 to 39 increased by 5.3 percent, while births among women aged 25 to 29 declined slightly by 0.1 percent.

Meanwhile, 28,101 deaths were recorded in September, a 3.9 percent decrease compared with the same month last year. With deaths outnumbering births, the country's population still saw a natural decline of 5,732 people for the month.
