Japan $35,951 / South Korea $36,227

Reference period: 2025 · World Bank · World Development Indicators

Raw difference, left minus right: -$276. The raw value for South Korea is higher than for Japan. This establishes neither superiority nor the cause of the difference. This is an economy-wide average, not a person's salary or a household's disposable income. The same average can coexist with different income distributions.

Median age

Japan 49 years / South Korea 44.5 years

Reference period: 2023 · UN DESA Population Division · World Population Prospects 2024

Estimated

Raw difference, left minus right: 4.47 years. The raw value for Japan is higher than for South Korea. This establishes neither superiority nor the cause of the difference. Median age differs from mean age. It locates the middle of the population, but does not directly give the older-age or working-age share.

Total fertility rate

Japan 1.208 births per woman / South Korea 0.72 births per woman

Reference period: 2023 · UN DESA Population Division · World Population Prospects 2024

Estimated

Raw difference, left minus right: 0.49 births per woman. The raw value for Japan is higher than for South Korea. This establishes neither superiority nor the cause of the difference. Total fertility rate is not the year's number of births or the completed family size of women who have finished childbearing. It summarizes age-specific fertility in a period.
