According to the Statistical Bulletin on Health Development in China in 20021year issued by the National Health and Wellness Committee on June 5438+02, the average life expectancy of China residents increased from 77.93 years in 2020 to 78.2 years in 20021year, and the maternal mortality rate was from16.9/1.
Life expectancy per capita, maternal mortality and infant mortality are important indicators to measure the health level of a country's residents internationally. Song Li, director of the Department of Maternal and Child Health of the National Health and Wellness Commission, said that in 20021year, the mortality rates of pregnant women, infants and children under 5 years old in China all fell to the lowest level in history.
According to the statistical bulletin, in terms of total health expenditure, the proportion of total national health expenditure to GDP in 20021year was 6.5%; Judging from the total number of medical and health institutions, by the end of 2002 1030935 million, including 36,570 hospitals and 97,779 primary medical and health institutions.
expected life
In short, the average life expectancy is to assume that a group of people, starting from the age of 0, will gradually shrink until the last person dies according to the current mortality rate of all ages. The average age of death of these people is life expectancy.
Theoretically speaking, the average life expectancy should examine the actual life process of the same group of people. In other words, how many people born this year will die this year and how many will die next year and the year after. Assuming that these people will all die by 100, then their average life expectancy is the average life expectancy. But this statistical method is unrealistic, because it takes a century to calculate the life expectancy of this group of people.
