"The effects of changing life span on certain life cycle measures of post-marital life are examined with the help of numerically computed values of such measures under various mortality and divorce levels. The results show that in the absence of divorce the increase in mean marital duration effected by a mortality decline is even greater than the increase in total post-marriage life. Thus, in such populations, the expected length of widowhood actually declines in spite of the fact that a greater proportion of women face widowhood as mortality falls. But this is not true for populations with moderate or high divorce levels, which would experience relatively smaller improvements in mean marital durations and consequently the length of post-dissolution life increases through a mortality decline in such populations."

借助在各种死亡率和离婚率水平下此类指标的数值计算结果,研究了寿命变化对婚后生活某些生命周期指标的影响。结果表明,在没有离婚的情况下,死亡率下降导致的平均婚姻持续时间的增加甚至大于婚后总生活时间的增加。因此,在这类人群中,尽管随着死亡率下降有更大比例的女性面临丧偶,但预期的丧偶时间实际上却在减少。但对于离婚率处于中等或较高水平的人群来说并非如此,这类人群的平均婚姻持续时间改善相对较小,因此,随着死亡率下降,这类人群离婚后的生活时间会增加。(英文和意大利文摘要)
