What's Behind the Surprising Turnaround in the World's Lowest Birthrate Nation? Has South Korea Escaped Its Demographic Crisis?

The nation long known for having the world's lowest birth rate is showing a surprising shift.

Recent data from Statistics Korea's "April Population Trends" report reveals a significant 18% year-on-year increase in births for the month, totaling 24,521 babies. This marks the highest figure for April since 2019 and the largest year-on-year growth rate for the month since records began in 1981. The total fertility rate for April reached 0.93, a rise of 0.13 points from the previous year.

For the cumulative period from January to April, the number of births reached 99,534, the highest for that period since 2019, with a record 15.5% year-on-year increase.

An expert in the field explained the connection, stating that in South Korea, childbearing is highly tied to marriage, meaning births are almost entirely dependent on wedlock. Since 2024, the number of marriages has been steadily rising, which is now acting as a crucial driver in reversing the low birth rate trend.

This shift follows a period of severe demographic concern. In mid-2024, the government declared a "population emergency" due to a sharp population decline and set a policy goal of raising the total fertility rate to 1.0 by 2030. The Bank of Korea had also warned that without effective measures to boost the low birth rate, the nation's economy could face negative growth by 2050.

The Turning Point in 2024

The strong April figures follow an observable trend that began in the previous year. South Korea's total fertility rate, which measures the average number of children a woman is expected to have in her lifetime, started to recover from 2024 after hitting a historic low of 0.72 in 2023. For context, a rate of 2.1 is generally needed for a stable population without migration.

Historically, the country's fertility rate exceeded 4 around 1970 before entering a long decline. After a brief recovery between 2006 and 2012, it resumed a downward trajectory, falling below 1 for the first time in 2018. The rebound in 2024 to 0.75 and a further increase to above 0.80 in 2025, as shown in recent statistics, marks the first time the rate has risen for two consecutive years in over a decade.

This demographic change correlates with rising marriage numbers. Registered marriages increased by 14.8% to 222,400 couples in 2024, leading to a 3.6% rise in newborns to 238,300 that year. The trend continued into 2025, with marriages reaching 240,000 couples and births rising to 252,400. Data for the first four months of 2026 shows marriages are still growing, up 6.8% year-on-year.

A Temporary Rebound or a Lasting Trend?

A senior official from Statistics Korea attributed the two-year fertility rate increase to several factors: a rise in marriages since 2022, an increase in the population of the primary childbearing age group (around 30 years old), and a more positive societal outlook on having children.

The official also noted that government policies are beginning to show results, alleviating some challenges associated with marriage and child-rearing. South Korea established a presidential committee on low fertility and aging society as early as 2005 and has since invested heavily in subsidies, with cumulative spending exceeding 380 trillion won since 2006.

The expert highlighted two key social factors: the current generation of women of childbearing age, who grew up in relatively affluent and caring environments, appears more inclined to marry and have children. Furthermore, the typical marriage today often involves couples with strong individual backgrounds, likened to a "merger of two small and medium-sized enterprises," making procreation a common expectation from the union.

Despite these positive signs, the expert cautioned that many young Koreans remain hesitant about marriage, primarily due to the perceived high financial and psychological costs of wedding and raising children, even with government support.

Whether the current data represents a fleeting improvement or the start of a long-term reversal remains uncertain. The expert suggested that the marriage window for this generation is sensitive to broader economic conditions and requires further observation. Notably, even with the recent uptick, South Korea's total fertility rate remains the lowest among sovereign nations, a position it has held since 2024.
