South Korea’s very low birth rate and ageing population have long served as a cautionary tale for other governments worried that they’ll see similar demographic challenges.

But now, for the second year running, more people in South Korea are having children. The 6.8% rise in births in 2025 is the largest rise since 2007, and has taken the country’s total fertility rate to 0.80, up from 0.75 in 2024. The news is being cautiously celebrated, but with South Korea’s overall population still shrinking, it is yet to reverse its demographic fortunes.

In this episode, we speak to Stuart Gietel-Basten, a demographer and professor of social science and public policy at Hong Kong University of Science and Technology, about how South Korea has got to this point and some of the structural issues the country still faces.
