摘要
平均预期寿命是世界公认的衡量人类进步的标准。本文以生命表为基础,主要依据我国第六次人口普查资料,计算各省市区的预期寿命并进行相关分析,计算结果表明,2010年中国人口平均预期寿命为78.17岁,男75.86岁,女80.68岁,已进入发达国家行列。预期寿命与婴儿死亡率呈负相关r=-0.789,与人均国民总收入呈正相关r=0.604。预期寿命女性比男性长4～7岁,符合一般规律。影响男性寿命低于女性的原因很多,本文重点讨论了遗传因素和生活方式的影响,并对预期寿命的地理分布进行分析。
The life expectancy is a standard that evaluates the advancement of human on the world. Based on the complete life tables and the data of the 6th censuses,this paper calculated every province life expectancy,and did correlation analysis.The results indicated that life expectancy in China reached 78.17 years,and life expectancy of male reached 75.86 years,and life expectancy of female reached 80.68 years,and had entered range of developed country. Between life expectancy and infant mortality rate were negative correlation r=-0.789. Between life expectancy and per capita national income were positive correlation r=0.604. It was true of general rule that life expectancy of female was longer 4 -7 years than life expectancy of male. There are many influencing factors that life of male is lower than life of female , and this paper discusses the impact of genetic factor and life style.
