Using Korean Longitudinal Study of Aging data, we examined the influence of older adults' individual characteristics (i.e. marital status, health and economic status) on life satisfaction, with the mediating effect of older adults' active participation in lifelong learning. As a result, some individual characteristics appeared to significantly determine both learning participation and life satisfaction. Economic status appeared to function as a significant predictor of older adults' participation in lifelong learning programmes, which ultimately resulted in a significant improvement in their life satisfaction. Marital status and health were also significant contributors to older adults' life satisfaction. The mediating model was tenable according to model-data fit indices.
