In Sweden, a regular population census has been conducted for more than 250 years, and according to the latest data, the male population recently exceeded the number of females. Scientists note that a similar situation is observed in other countries, in particular, Norway, Switzerland, etc.
In Western countries, women have always outnumbered men, but in 2015 the situation began to change - then in Sweden it was recorded that men exceeded the number of women by 277 people, and for the year the gap increased to 12,000, and scientists are sure that the number of men will be further increase.
In the European regions, boys are born on average 5 more than girls, but because of the high life expectancy among women, the beautiful half of humanity is numerically greater than the male. Experts can explain the current situation by two reasons: men will live longer and the mass influx of refugees is mostly young men from Africa and the countries of the Middle East. Only in Sweden over the past and current years, more than 30,000 adolescents who became orphans were granted asylum.
But, as mentioned, not only in Sweden there is a tendency to increase the number of men. For example, in Norway the situation has changed even earlier than in Sweden. In Denmark and Switzerland, the number of men and women is approximately the same today. In Germany half a century ago, there were 87 men for 100 women, and today - 96, and experts suggest that in the future the number of men will only increase.
Now sociologists have a new task - to determine whether there are risks of such a change in the relationship between the male and female half of humanity. But some researchers are already worried that an increase in the male part of the population will lead to violence and sexual harassment, as many men will remain alone.
According to a recent WHO report, the world's average life expectancy has increased over the past 16 years. According to some reports, people began to live for 5 years longer, despite the fact that women are still for several years continue to experience men. But many experts suggest that men will eventually equalize with women, in particular, this may contribute to an increase in the number of men.
It should be noted that the number of women has always exceeded the number of men - such conclusions were made by scientists after studying the DNA of different peoples. To establish the demographic history, specialists used a new method of extracting genetic information - sequencing and compared the Y chromosome and mitochondrial DNA.
As a result, they found that even before the resettlement of people from Africa, women were quantitatively higher than men, and in some countries this trend was maintained.
A number of specialists suggest that the reason for such a ratio could be polygyny (when one man has relationships with several women).
Also, scientists noted that there is a regional difference, for example, the inhabitants of Africa have fewer genes in the male line, most likely because of the spread of the people to the south and east of Africa, which began about 3 thousand years ago. But among the Indians living in America, more women's genes have been identified, which may be due to the large number of representatives of this people in the New World.
