Korean Longitudinal Study of Aging

The Korean Longitudinal Study of Aging (KLoSA) is a nationally representative sample of more than 10,000 persons at least 45 years of age in the Republic of Korea (South Korea). Its age cut-off reflects an earlier transition to retirement in several Asian nations. It was first conducted in 2006, with biennial follow-up waves since then. The KLoSA interviews all age-qualifying individuals in a household. Among other topics, it collects information on work and income and health and disability and includes detailed questions on family transfers. It collected work-history data in 2007.
