The imbalance of sex ratio brings a lot of harm, mainly the social phenomenon that men can't marry wives. Affect social stability. Here, I mainly talk about the reasons for the imbalance of sex ratio. There are various views that it is caused by family planning and fetal sex identification. Of course, the most important thing is the idea of "son preference". In fact, the problem of unbalanced sex ratio has always existed. Before B-ultrasound, baby girls were mainly abandoned. After B-ultrasound technology, it was an abortion.

Let's look at these two statistical tables. The sex ratio has been relatively stable at around 108%. According to the National Bureau of Statistics, from 1980 to 20 14, 675 million people were born in China. The average sex ratio in these 34 years is 165438+. If this is the case, then the data on the statistical table is due to the increase of women's life expectancy, which leads to an increase in the proportion of women's data. The average life expectancy of men is obviously lower than that of women, the sex ratio should be less than 100, and the statistics are the total population, not the marriageable age population, so it is more than 30 million.
