In December 2024, the share of South Koreans ages 65 and older surpassed 20% for the first time, making it what demographers like us call a “super-aged society.” By August 2026 that share had risen further, to 22.1%.
That label can sound like a diagnosis, but population aging is not inherently a problem. In part, it reflects demographic progress: Fewer people are dying prematurely, and people are living longer due to improved living conditions. Thus, an older population can simply be a sign of society having grown safer, healthier and demographically more mature.
