利用人类死亡率数据库中29个高收入国家人口（1751-2004）的数据，我们回顾了e（0）中性别差异的趋势。在1900年代的大部分时间里，这一差距的扩大主要是由于男性死亡率下降的速度慢于女性，以前的研究将其归因于行为因素（例如，吸烟）。最近，大多数国家的差距开始缩小，研究人员试图用同样的因素来解释这种逆转。然而，我们的分解分析表明，对于大多数国家来说，最近的缩小主要是由于死亡率年龄模式的性别差异，而不是死亡率性别比的下降：相同的死亡率下降率对女性的e（0）的增益小于男性，因为女性的死亡在年龄上的分散程度较小（即，生存更矩形）。
Using data from the Human Mortality Database for 29 high-income national populations (1751-2004), we review trends in the sex differential in e(0). The widening of this gap during most of the 1900s was due largely to a slower mortality decline for males than females, which previous studies attributed to behavioural factors (e.g., smoking). More recently, the gap began to narrow in most countries, and researchers tried to explain this reversal with the same factors. However, our decomposition analysis reveals that, for the majority of countries, the recent narrowing is due primarily to sex differences in the age pattern Of mortality rather than declining sex ratios in mortality: the same rate of mortality decline produces smaller gains in e(0) for women than for men because women's deaths are less dispersed across age (i.e., survivorship is more rectangular).
