What should I do when I'm old after 70? How will China's population grow old after the 1970s

in another 20 years, what should we do if we are old after 70? How will China's population develop after 70 years old? What do you think?

With the state's regulation and control of fertility, China's population has been maintained at about 1.4 billion in 20 years. China is still a country with a large population in the world. Now the country has released the second child policy. In the near future, China may be liberalizing the third child. As long as the natural growth rate of the population is determined according to the national conditions and according to the resolution of the National People's Congress, China's population will remain at about 1.4 billion 。 According to China's poor family planning policy and population structure, in another 20 years, China's population will be controlled in a moderate range, and the population will not change too much.

Population depends on fertility (fertility), mortality (average age). Fertility willingness is also a major factor to intervene in fertility rate. The willingness of the Post-70s to have a second child is higher (but limited by age), and the willingness of the post-80s to have a second child is relatively low (with great pressure on life). Although the fertility is declining, the assisted reproductive technology is making progress. As long as the fertility is willing, most of them will have a second child Under the circumstances, the fertility requirements can still be fulfilled. In 1982, only 4.91% of China's population aged 65 years or above had changed much compared with 1953. By the end of 2000, the proportion of people aged 65 and above reached 7%, indicating that China has entered the ranks of countries with elderly population. By the end of 2007, the number of people aged 60 and above exceeded 153 million, accounting for 11.6% of the total population.

In fact, the problem is not how many people, but the population structure. If the structure is reasonable, then China's population of about 600 million will be a big country. But now the problem is that soon the elderly population may account for 1 / 4, and the population is on the decline. There are fewer and fewer young people, and more and more elderly people. Even if family planning is effective, China will have a difficult time in the next few decades. After that, there will be a phenomenon of vast land and sparse population. Only those in 60, 70, 80 and 90 will be very sad! China's population structure will not change greatly in 20 years. This is reflected in the fact that the elderly population will be more likely to exceed 15%, while the proportion of newborns and school-age children is the same or slightly increased compared with the present. Although the requirement of two-child birth is relaxed, with the development of society and the improvement of people's quality, the concept of supporting children for the aged in the past will be more and more weak.
