日本人の初婚表 : 1975年

抄録

This paper presented net nuptiality tables for males and females in Japan, 1975. Table 1 and table 2 are based on a marriage registration data for the year 1975, for numerators of central marriage rates, and on 1975 Population Census data on single males and females for denominators of central marriage rates, and on death rates of single male and female from "Life Tables by Marital Status [1]" of 1975. The definitions and notation of these tables are the same as cited in the previous paper ([3] Itoh and Yamamoto, 1977. "First-Marriage Table for Japanese Women in 1970 and Projections of the Number of Marriages to 2000" Jinko Mondai Kenkyu, Vol. 141, p. 51). According to the tables, 87.43 percent of newly born males and 91.21 percent of newly born females may expect to marry during their whole life. These figures, (e^^○^s_0) the chance at birth that a newly born baby will eventuary marry, are the simplest summarized index derived from net nuptiality tables as is the expectation life at birth in a life table. And they are also important figures when the marital fertility rates based on marriage-duration-specific birth rates are compared with the conventional reproduction rates [22].
