Abstract In different populations there is a common curve describing first-marriage frequency (first marriages per woman) as a function of age for each cohort. To fit the variety of patterns of human nuptiality it suffices to choose the age that serves as origin for a standard curve of first-marriage frequency, and to choose appropriate horizontal and vertical scales for the curve. The prevalence of a standard form for first-marriage frequency implies that the proportion ever-married in any cohort also rises along a standard curve, subject to choice of origin (the earliest age of first marriage), vertical scale (the proportion ever-marrying by the end of life), and horizontal scale (the pace at which the proportion ever-married increases with age). A mathematical expression (a double exponential) is found to fit the risk offirst marriage (among those who ever marry), and some of the implications of uniform features of nuptiality in different populations are discussed.
摘要 在不同的人群中，存在一条共同的曲线，用于描述各队列中女性初婚频率（每女性初婚数）随年龄的变化。为了适应人类婚姻模式的多样性，只需选择作为初婚频率标准曲线原点的年龄，并为曲线选择适当的水平和垂直刻度即可。初婚频率标准形式的普遍性意味着，在任何队列中，曾经结婚的比例也沿着标准曲线上升，这取决于原点（初婚的最早年龄）、垂直刻度（生命结束时曾经结婚的比例）和水平刻度（曾经结婚的比例随年龄增长的速度）的选择。发现一种数学表达式（双指数）适用于初婚风险（对于那些曾经结婚的人），并讨论了不同人群中婚姻统一性的一些含义。
