性别比例的长期变化与家庭经历的关系进行了研究。本文概述了两种理论观点:Guttentag和Secord(1983)的社会交换适应理论和性选择理论。由于出生人数的大规模变化和男女结婚年龄的典型差异,1965年至20世纪80年代初,美国在结婚年龄存在低性别比例。然而,目前的高性别比将持续到本世纪末。较高的性别比例似乎与较低的离婚率、男性对有经济回报的职业的承诺、男性照顾孩子的意愿、较高的生育率和较高的性暴力率有关。性选择理论引起人们对数量较大的性别中的无性竞争的关注。
Secular change in sex ratios is examined in relation to experience in the family. Two theoretical perspectives are outlined: Guttentag and Secord’s (1983) adaptation of social exchange theory, and sexual selection theory. Because of large-scale change in number of births and typical age differentials between men and women at marriage, low sex ratios at couple formation ages existed in the U.S. between 1965 and the early 1980s. The currently high sex ratios, however, will persist until the end of the century. High sex ratios appear to be associated with lower divorce rates, male commitment to careers that promise economic rewards, male willingness to engage in child care, higher fertility, and higher rates of sexual violence. Sexual selection theory calls attention to intrasexual competition in the numerically larger sex.
