The main cause of the aging problem in China is due to the improvement of medical condition,social culture and scientific technology so both the birth rate and mortality rate of China keep decreasing while the average life expectancy of the people keeps increasing.In 1950,the average life expectancy of China was less than 40 years old and has risen to 71 years old now.
The "Birth Control" policy of China implemented in the late 1970s focuses on the control of the population.According to the census,in the past 20 years,China has reduced 240 millions of birth.As the structure of the population could not be changed,when fast growth of the population was under control,the population structure could not but develop in the trend of aging,thus caused the historical change of the age structure of Chinese population.
The problem of aging in China has a far-reaching impact on the China’s economic sustainable development and is a double-edged sword,which has both positive and negative aspects.The key point lies in how to convert the negative aspects into the positive aspects and how to develop the positive impact and reduce a negative one.
In the old days,American families were bigger.People had more children,and grandparents and great-grandparents lived with their families.But now,families are smaller,and many old people
live alone.At the same time,Americans are living longer and longer.The number of old people is always growing.
Some old people like to stay in their old homes.They do not want to move from their old homes.They do not want to move from their hometown.They are near their .friends and family.But some do not have a lot of friends.They want to meet new people.They want to live in a quiet place with other
people of their age.
A large number of old people are moving to the South.It is warm there.You do not have to walk through the snow in winter,or pay a lot of money for heating.
