What are the chances of people living to 70 years old?

According to statistics, as of June 2020, the average life expectancy of men in China is 77. 1 year, and that of women is 82.6 years. This means that the probability that Chinese men generally expect to live to 70 years old is 77.1-70/77.1= 9.7%, while the probability that women expect to live to 70 years old is 82.6-70/82.6= 14.6%, with a total probability of 9.7%+/kloc.

In addition, according to the data of China National Bureau of Statistics, by the end of 20 18, the average life expectancy in China is 76.9 years, 75.2 years for men and 78.7 years for women. This means that the probability that men in China generally expect to live to 70 years old is 75.2-70/75.2=6.7%, while the probability that women expect to live to 70 years old is 78.7-70/78.7 =1.5%, with a total probability of 6.7%+1/kloc.

As can be seen from the above, the probability of China people living to 70 years old has greatly increased from 20 18 to 2020, from 20 18/8/8% to 24.3% in 2020, but it is still far below the life expectancy, so more efforts are needed to improve people's health.
