1.Per person's life expectancy reflects the present death level, though call the life expectancy, how old but does not represent a crowd can really live
"Cup to cup calls for song, how much life? " Cao Cao is eternal to sigh with regret, initiates people's inquisition of the life length: How long can people live on earth?
"There is Chinese Methuselah the most in history that conclusive file proves, dies at the age of 122 years old and 164 days. " Chinese population and Jiang WeiPing, director of research and development centre, introduced, " this was born in French women of February 21, 1875, it is Jenny road that exchanges Karmen. "
"The long-lived old man's champion notes down, has represented the level of the quality of its life to a certain extent. " Jiang WeiPing says, through the ages, good health and a long life has been the happy index that people have pursued all the time. However, because are limited by the economics and society condition, medical level of hygiene, the life-span of crowd of different period, different society is far from each other; Because individual differences such as the physique, heredity, life style,etc., everybody's life size differs greatly.
Then, under certain economics and society condition, how to consider all people's life size?
"The most frequently used index is the population average life expectancy. " Zhai ZhenWu, dean of society of the People's University of China and people, says, per person's life expectancy is in brief, assume, have one people, since 0 years old, until every age bracket mortality pass by year by year at present, the team shrinks gradually, until the last person spends the remaining years till death. Count this batch of per capita ages of death, it is the life expectancy.
Zhai ZhenWu further explains, theoretically, per person should investigate that criticize people's real life course the samely in life expectancy. One people that born this year then, will how much does it die this year, how much does it can die next year, the year after next, assume by 100, this group of people all die, their average life span, it is per person's life expectancy. But this kind of statistical method is unrealistic, because after the life expectancy to be counted this group of people should probably waited until one century.
Refered per person's life expectancy on demography, mean the current life expectancy. What is " Now " ? According to (nowadays annual) at present Mortality predict. For example, this group of people born this year is a year old by next year. The mortality a year old relates to medical condition of next year,etc., and next year's situation is unknown. Then, according to 1 -year-old people's death probability, count this group of people's death quantity in a year old. When they live to the age of 2, according to the 2 -year-old death probability of this year, count its death toll. And so on and so forth, go down year by year, until this group of people all die, calculate age of their average death.
"Per person's life expectancy reflects the present death level, though it calls the life expectancy, how old but does not represent this group of people can really live. " Zhai ZhenWu emphasizes, " because it is that mortality is calculated as the foundation instantly, in fact, mortality is constantly changeable. For example the people that born now can expect living 74 years old, after after so many years past, medical level go up, may live to the age of 100. "
2.Per person's life expectancy weighs a country or the development level of economics and society and overall target of the service level of the health care of the present stage in the area
"Per person's life expectancy is calculated with mortality, so, the factor influencing its level is the mortality. " Qiao XiaoChun, professor of research institute, population of Peking University, thinks, realizes " per person's life expectancy is raised by a year old " Goal,reducing soon is dead level.
Zhai ZhenWu thinks, removes the inherent cause, primary reason for influencing mortality is the social stability, if under chaos caused by war or society's turbulent shade all the year round, life and even life will lack the guarantee, even if ensure, the mood is difficult to turn better. Secondly, it is the socio-economic development and service level of the health care.
According to service level of the health care, include two respect contents. First, medical engineering level, if got variola before, there was not treatment technology, cause hundreds and thousands of people death. Second, medical treatment ensures competence. Seeing the doctor will spend money, if the medical insurance system is imperfect, ensure competence to be low, get serious disease and look down upon too, will raise mortality naturally.
