A great number of unwanted pregnancies occurs annually in Australia, but more sociological data are needed to explore this current problem. If one defines unwanted pregnancy as one which was unwanted by either partner weeks before the conception, it can be estimated that approximately two in three pregnancies are unplanned and one in two is unwanted.
澳大利亚每年都会发生大量意外怀孕的情况,但需要更多社会学数据来探究当前这一问题。如果将意外怀孕定义为在受孕前几周夫妻双方中有一方不想要的怀孕,那么据估计,大约三分之二的怀孕是意外怀孕,二分之一的怀孕是意外且不想要的。
