June Births Surpass 23,000
The number of babies born in South Korea in June 2026 reached 23,111, an increase of 3,115, or 15.6%, compared to the same month last year. According to the “June and Q2 2026 Population Trends” report released by the National Data Agency on August 26, the crude birth rate—representing the annual number of births per 1,000 people—stood at 5.5.
The total fertility rate, which indicates the average number of children a woman is expected to have in her lifetime, rose to 0.88 in June, up 0.11 from 0.77 in the same month last year. The Q2 total fertility rate also clocked in at 0.88, showing an upward tick across all 17 cities and provinces compared to the same period last year. The real takeaway from this announcement is that both the number of births and the fertility rate have bounced back simultaneously in a country long known for its ultra-low birth rate.
Growth Carries Over into Quarterly and First-Half Stats
This rebound isn’t just a one-off blip for June. The number of births in the second quarter of 2026 was 70,791, up 15.8% (9,675 births) from 61,116 in the same period last year. Looking at the first half of the year from January to June, the cumulative number of births reached 145,804, a 15.4% increase year-over-year. Following a strong first quarter, the second quarter also saw double-digit growth in births.
Monthly figures can be easily skewed by seasonal changes or the timing of birth registrations, making it tricky to gauge long-term trends from a single month. However, seeing the same upward movement across two quarters and the first half of the year adds much more weight than a single month’s rebound. And since the Q2 total fertility rate rose across every single province and city, we know this isn’t just a localized shift.
The Lag Between Rising Marriages and Births
There were 21,075 marriages in June, an increase of 14.0% (2,588 marriages) from 18,487 in June 2025. Across the entire second quarter, marriages hit 62,065, up 4.9% from the same period last year. Because a high percentage of births in South Korea occur within marriage, a bump in weddings tends to be followed by a rise in births after a certain lag. That’s why the recent uptick in marriages is frequently pointed to as a leading indicator of this current rebound in births.
The National Data Agency hasn’t pinned this increase in births to a single cause. Instead, they analyze it as a combination of delayed weddings finally taking place post-pandemic, an increase in the population of women in their 30s (the primary childbearing demographic), and a shifting cultural mindset that views having children more positively. While the rise in marriages is a crucial piece of the puzzle, changing demographics and social attitudes play a vital role too.
Given the time it takes to conceive and deliver a child, you can’t simply draw a straight line between marriage and birth numbers in the exact same month. The current rise in births is much more likely reflecting the recovery in marriages that has been building up over a longer period, well before just the last month. Whether this trend in marriages holds steady will be a key metric for predicting future birth rates.
Distinguishing a Rebound from a Trend Reversal
In June, the number of deaths was 27,794, a 2.0% increase from the same month last year. With deaths outpacing births by 4,683, the natural decline of the population continued. Even with a noticeable jump in babies born, South Korea’s overall population structure hasn’t suddenly flipped to a growth phase. A total fertility rate of 0.88 is still far below what’s needed to sustain the population long-term.
Divorces in June stood at 7,688, a 13.5% jump from a year earlier. The National Data Agency notes that having two more business days available to file paperwork compared to last year played a part in this increase. Rather than viewing the divorce rate as a direct factor explaining births or population decline, it should be looked at separately, keeping those filing schedule differences in mind.
Keep in mind that monthly birth and death statistics are provisional figures, estimated and tallied based on the month they occurred while accounting for delayed registrations. These numbers could be adjusted as more data comes in. What these results do offer is a rare sign of a rebound against the narrative that the “demographic cliff” is an unavoidable, one-way street. However, we’ll need to watch upcoming quarterly and annual data to figure out if this is just a sudden wave of postponed marriages and births crashing all at once, or the beginning of a lasting turnaround.
