个人收入对按年龄分列的死亡率的影响：生物效应与社会经济效应
Impact of personal income on mortality by age: biological versus socio-economic effects
摘要：
人均收入对预期寿命的影响有充分的文献记载，主要是通过对多国样本的研究。然而，人们预计在寿命的两端，也就是说在婴儿早期和85至100岁的老年人年龄组中，相关性相当弱。原因是，在这两个方面，死亡率在很大程度上受生物因素而不是社会经济条件的控制。为了验证这一猜想，我们探讨了收入对年龄组的影响，分别在法国，美国和韩国。更准确地说，我们在每个国家尽可能多的地区子单位中比较收入和死亡率数据。一个值得注意的论点是，与普遍看法相反，个人收入与婴儿死亡率（即一岁以下死亡率）的相关性很弱。更广泛地说，我们推测，对这三个国家的分析所揭示的共同模式也适用于其他发达国家。
英文摘要：
The influence of per capita income on life expectancy is well documented, mostly through studies of multinational samples. However, one expects fairly weak correlations at both ends of the life span, that is to say in early infancy and in age groups of elderly from 85 to 100 years. The reason is that at both ends mortality is largely controled by biological factors rather than by socio-economic conditions. In order to test this conjecture, we explore the influence of income on age groups, separately in France, the United States and South Korea. More precisely in each country we compare income and mortality data in as many regional subunits as possible. One noteworthy constatation is that, contrary to a common view, personal income is only weakly correlated with infant mortality (i.e. mortality under the age of one year). More broadly, we propose as a conjecture that the common pattern revealed by the analysis of the three countries is also valid in other developed countries.
