Social cohesion — South Korea · Synthesis
Moderate income inequality but the highest elderly poverty rate in the OECD, the largest gender pay gap in the OECD and youth under intense pressure — the fractures of unevenly shared economic success.
Citoyen synthesis for the Social cohesion and inequalities category in South Korea. Grounded in the sector's quantitative data (Statistics Korea, OECD). All values are the latest realized observation available — never a forecast. Assessments are kept distinct from sourced facts. Data last updated: June 2026.
1. State of play — where social cohesion stands
Moderate income inequality. The Gini index of disposable income stands at around 0.33 (OECD), above the European average but close to Japan, well below the United States. Strong growth has broadly benefited the population, but unevenly.
The highest elderly poverty rate in the OECD. South Korea has the highest elderly poverty rate in the OECD (of the order of 40%): the generations who built the economic miracle did not benefit from a mature pension system, and many work late in precarious jobs (see Labour and Health categories) — a key factor in elderly suicide.
A large gender pay gap. South Korea has one of the largest gender pay gaps in the OECD, linked to low female labour-force participation and the glass ceiling — a challenge for equality and for the birth rate (see Labour and Economy categories).
Youth under pressure. Academic pressure (see Education category), housing costs (see Housing category) and the difficulty of accessing regular employment fuel youth malaise, linked to the world's lowest birth rate.
Persistent dualism. Labour-market dualism (regular/precarious workers, see Labour category) is a matrix of inequality, cutting across gender and generational divides.
“South Korea has the highest elderly poverty rate in the OECD: economic success has not benefited older generations.”
2. Outlook — where social cohesion is heading
Reducing elderly poverty. Strengthening the pension system and the incomes of the elderly — the poorest in the OECD — is the central social challenge, linked to suicide prevention (see Health category).
Gender equality. Closing the pay gap and improving women's participation is a challenge for equity and for supporting the birth rate (see Economy category).
Youth and housing. Reducing pressure on young people (housing, employment, education) is linked to the national demographic crisis.
Reducing dualism. Attenuating labour-market dualism is a cross-cutting lever for reducing inequality.
The open questions. Three issues will shape the period: (1) reducing elderly poverty; (2) closing the gender gap; (3) easing pressure on young people.
“The largest gender pay gap in the OECD and youth under pressure fuel deep social malaise.”
3. International comparison — South Korea among its peers
Placed in its environment, South Korea displays moderate income inequality but acute social fractures (elderly, women, youth).
Three takeaways. (1) Inequality: moderate. With a Gini of ≈ 0.33, South Korea is close to Japan, above France (≈ 0.29), well below the United States (≈ 0.39–0.41).
(2) Elderly poverty: the highest in the OECD. A major downside of the South Korean model, without equivalent among the developed countries compared.
(3) Gender gap: the largest in the OECD. South Korea's gender pay gap is the most pronounced in the OECD, linked to the demographic crisis.

Methodological note — the synthesis keeps sourced facts distinct from assessments, stays neutral, dates each figure, and does not extrapolate beyond the sources. The Gini covers disposable income after redistribution. All values are the latest realized observation available (no forecast). Note generated by AI, human review required. Same safeguards as the rest of the observatory.
