Korea’s high older adult employment rate helps reduce poverty by 3.9–7.9 percentage points compared to countries like Japan and Australia. At the same time, Korea’s extensive private transfer income lowers poverty by 2.9–4.9 percentage points. However, the most significant factor driving Korea’s high poverty rate is its inadequate public pension system. If Korea’s public pension benefits aligned with those of developed nations, poverty would decline by 24.1–50.2 percentage points. Despite mitigating effects from labor market participation and private transfers, insufficient public pension income remains the dominant cause of older adult poverty in Korea. These findings highlight the urgent challenge of ensuring income security amid rapid population aging and low fertility rates.  \nSESSION 7275 (POSTER)   \nAbstract citation ID: igaf122.2760  \nRETIREMENT FACTORS DRIVING SOUTH KOREA’S  \nHIGHEST OLDER ADULT POVERTY RATE AMONG  \nOECD NATIONS: A DECOMPOSITION ANALYSIS  \nSeoyeon Ahn1, Eunsun Kwon2, Ji Young Kang3, and  \nSojung Park4, 1.
