During the 1970s the abortion law changed twice in Norway. As of 1976 induced abortion was accepted on social indications, while abortion on womens' demand was introduced in 1979. This study presents age-specific abortion- and birth rates as well as age- and parity-specific abortion ratio from 1972-1981. From 1972 to 1974 the number of induced abortions increased. Since then the general abortion rate has decreased. For all parity groups the number of pregnancies terminated by induced abortion increased during the first 3 years of the study. While nulliparous women showed a continuous increase in the abortion ratio throughout the study period, the abortion ratio for parous women has been relatively stable since 1975. Through the use of induced abortion nulliparous mothers postpone the birth of their first child. Therefore induced abortion contributes to an increasing maternal age at first child birth. The present study can support the hypothesis that multiparous women, among other means, have used induced abortion to establish the 2-child family norm during the 1970s.
20世纪70年代，挪威的堕胎法变动了两次。截至1976年，基于社会指征的人工流产被认可，而1979年开始允许应女性要求进行堕胎。本研究呈现了1972年至1981年按年龄划分的堕胎率和出生率，以及按年龄和胎次划分的堕胎比。1972年至1974年期间，人工流产数量增加。自那时起，总体堕胎率有所下降。在研究的头3年里，所有胎次组中因人工流产而终止的妊娠数量都有所增加。在整个研究期间，未生育女性的堕胎比持续上升，而自1975年以来，已生育女性的堕胎比相对稳定。通过人工流产，未生育母亲推迟了她们第一个孩子的出生。因此，人工流产导致初育时母亲年龄增加。本研究可以支持这样一种假设，即多子女母亲在20世纪70年代通过人工流产等方式来确立二孩家庭模式。
