1. Introduction
The population in Thailand is increasing. In 2013, there was 12.7 percent of the overall population that corresponded to the definition of the UN, which said: “Any country that has an aging population, of more than 60 years old and the criteria is more than 20 percent, it is becoming an aging society country.” Theaging population consists of males, 56.7 percent, and females, 43.3 percent. Thus, Thailand is already becoming an aging society country and effectively changing the economic and societal structure (Thailand National Statics, 2013).
