Why are there more women?
How to sing in a famous song, according to statistics for 10girls only have 9 children. And in some regions even less. To what extent such data correspond to the truth and why more women than men, we try to find out in this article.The sex ratio is affected by many factors. Let's narrow down a few of our research and find out where and why there are really more female females than males.
Sex ratio in different countries, no matter howstrange, varies. While in most European countries the proportion of the female population is indeed generally larger than that of the male population, in the Asian countries, especially in China, the situation is exactly the opposite. In China over the past 30-40 years, there has been a visible imbalance in the number of women and men. Now there are about 115 men for 100 women. In Russia, according to data for 2014, there are about 0.86 men per woman.
When determining the sex ratio in differentcountries always take into account not only the geographical position, but also the age of men and women. In Russia, for example, boys are always born more than girls. However, by the age of 30 the alignment of forces is changing. The problem is that the average life expectancy of men is an order of magnitude lower than that of women. It is believed that men are more often at risk of getting various diseases, are more prone to stress, more often work in hazardous industries, etc. Therefore, to a very old age, few of them live.
There is such a thing as gender imbalance- this phenomenon, in which there is an increase in the number of female or male populations under the influence of external factors. So, for example, after large-scale wars, especially after World War I and World War II, the number of the female population has significantly exceeded the number of men, since the latter very often died in battle.
If we talk about military times, it's worthto mention also the so-called "phenomenon of the war years" - during the period of aggravation of military conflicts, according to statistical data, the proportion of newborn males for unexplained reasons increases in comparison with newborn females.
In China, the establishment of internalthe demographic policy of the state, according to which there must be only one child in each family, has led to the fact that the male population in the country has become more than the female population.
