Overview
- Provisional 2025 data show 254,500 births, up 6.8% year on year for the biggest increase since 2010, with the total fertility rate rising to 0.80 from 0.75.
- Deaths climbed to about 363,400 last year, leaving a natural population decline of roughly 110,000 for a sixth consecutive year.
- Officials attribute the rebound to more marriages and a larger cohort of women in their early 30s, noting shifting attitudes toward childbearing.
- The upswing skews toward older mothers, with the average maternal age at 33.8 and a record 37.3% of births to women aged 35 and over.
- Seoul is preparing a five‑year demographic roadmap and projects the fertility rate to stay above 0.8 this year with an optimistic path toward about 1.0 by 2031, even as Japan logged 705,809 births for a 10th straight annual drop and Singapore’s rate fell to 0.87.
