Ageing of population presents itself as a serious matter due to the reduction of birth rates and so on in the world. 

According to information recently released by the United Nations, the number of people at the age of over 65 reached 771 million in the world as of July this year, about 10 percent of total global population. This means that the elderly population has increased three times as compared to 1980.   

It is reportedly anticipated that the number will increase by nearly 16 percent in 2050, over two times greater than that of children under five.
