This picture, however, would demonstrate the weak points of services provided and delivered to the elderly.

This article is focused on ageing and the rapid ageing population growth, from future health care costs prospectus. It reviews ageing population statistics in several courtiers as well as Iran, to illustrate the significance of the ageing population growth in the next decades. Nevertheless, the health care costs for elderly people are described and the considerable differences between health care costs of under 65 years and over 65 years population are verified. Then, the importance of ageing population and future health care costs studies concluded. Giving the fact, that Iran like many other countries will face a rapid increase in ageing population within the few decades, from raw information and data, it is roughly estimated that the net effect of the ageing population growth is to increase health costs per capita, more than 2.5 times in 2050compare to year 2000. Finally, policy and decision makers were asked to pay attention to the magnitude of ageing population growth for planning and management of the future health care system in Iran, based on the reality of resource scarcity and increasing demand for elderly peoples, health care in the future.
