  • The purpose of this article is to review the current states and future trends in the more developed countries(MDC), the less developed countries(LDC), and Korea. In 2009, the percentage of persons ages 65 and older in the world's population is 8%. However, the ratio of elderly to the total population is higher in MDC than LDC (and Korea). In future, population ageing will be a serious social problem in the LDC (and Korea). Population ageing process will occur at a much faster rate in LDC (and Korea). The reason is that the demographic transition in LDC (and Korea) has occurred in much shorter and recent periods. Though the ageing indices such as the old-age dependency ratio, aging index, and the median ages are higher in MDC, they will change rapidly in LDC. In addition, the oldest old population will increase in LDC than MDC. Therefore, when establishing the government policy related to population ageing, we need to consider the different population ageing process between in MDC and in Korea(or LDC).
