South Korea’s demographic score looks stronger than the popular narrative because the current metric window still captures a country with a very high working-age share and strong human capital. In other words, the system is still benefiting from the tail of earlier demographic strength even as long-run concerns become more obvious.
That does not mean the problem is imaginary. Median age is already high and the future trajectory is worse than the short-run score suggests. Korea’s ultra-low fertility is a real strategic issue. It simply lands more forcefully beyond the current data horizon than inside it.
For now, the right read is that demographics still support the Korean system in the near term while threatening to become a much larger drag later. The 5/5 score should therefore be read as a present-tense result, not as a claim that the long-run demographic outlook is easy.
