我的重点是女婴存活率不及男婴的一半展开的。以2017年数据为例，我国20至24岁人口的男女性别比约为110.98；14至19岁人口的男女性别比约为117.7；10至14岁人口的男女性别比约为118.46；5至9岁人口的男女性别比约为118.55；0至4岁人口男女性别比例约为114.52。,二胎这个我知道，但要是说女婴只有男婴一半的存活率，那你怎么解释呢？
My focus is on the survival rate of girls, which is less than half that of boys. In 2017, for example, the sex ratio of the population aged 20 to 24 is about 110.98; the sex ratio of the population aged 14 to 19 is about 117.7; the sex ratio of the population aged 10 to 14 is about 118.46; the sex ratio of the population aged 5 to 9 is about 118.55; and the sex ratio of the population aged 0 to 4 is about 114.52.
