Population of girls in the world. Who is more on Earth at the moment - men or women? There are statistics

According to UN estimates, in 2015 there are 101.8 men for every 100 women in the world. The number of men has grown steadily every year since 1960. The Pew Research Center has produced a new map showing that the sex distribution is uneven. For example, in the countries of the former Soviet Union, women outnumber men. And in Asia, Arab countries and North Africa, on the contrary, there are more men, reports.

Latvia, Lithuania, Armenia, Belarus, Russia, Estonia and Ukraine are among the countries with the largest female population.

The same countries lead in the difference between the life expectancy of men and women. In Belarus, for example, men live on average 65.3 years, and women 77 years. The difference between these indicators is greater only with Syria, which is engulfed in civil war.

Differences in sex ratios change with age. So, in the Russian Federation, the gender ratio differs in different age groups. More boys than girls are born there every year. The group under 31 is also dominated by men. But already from the age of 32, the female population is growing. And this difference is increasing every year.

This gap is due to historical reasons. The history of the 20th century seriously influenced the demography in the USSR. According to the first census in Russia in 1897, there were 98.9 men per 100 women. The same balance is today in the United States (98.3 men per 100 women).

The percentage of women in Russia began to rise during the First World War, the Civil War, famine and the Great Terror from the USSR. In 1939, there were 91.9 men for every 100 women. The Second World War had a huge impact on the proportion of the population, because it was mainly attended by men. In 1959, the ratio was 81.9 men per 100 women. On the territory of Ukraine, this figure was 79.7 against 100, and, for example, in Azerbaijan - 92.3. In 1989, in the USSR as a whole, there were 89.5 men per 100 women.

The difference widened in the 90s due to male mortality at an early age. This was due to alcoholism and other addictions.

The ratio of women to men in the world is in balance. Statistics show that in 2017, the male population is 50.4%, while women are 49.6%. From the middle of the 20th century, the number of men began to grow rapidly, according to experts from the Pew Research Center research group.

The ratio of men to women in the world

According to the UN, 100 women in the world correspond to 102 men. However, in some states, the ratio of women to men has a noticeable difference.

Martinique tops the list of countries with a high female rate, with 85 males per 100 females. The same indicator is observed in the following countries:

• Japan;
• Brazil;
• France;
• Germany;
• Mexico;
• Italy.

Overall, the number of countries with a high female population is 108.

The United Arab Emirates is the leader among states with a high male population: for example, there are only 100 women out of 274 men. A high percentage of the male population remains in countries such as China, India, among the population of North Africa and the Middle East: there are 55 countries in total. The difference is about 6-8%.

Experts believe that the current situation has developed not for the reason that many boys are born, but under the influence of two other factors:

1. Most women are deprived of the opportunity to take part in the population census due to religion and cultural values;
2. In these countries, there is a high level of guest workers.

Based on this, experts have come to the conclusion that the ratio of women and men in these states is equal.

A dangerous situation is observed in the Eastern countries, where a low percentage of women have developed due to abortion. Researchers and the authorities themselves suggest that this ratio, with 107 men per 100 women, could trigger violent behavior on the part of the male population. In China, in order to avoid dangerous consequences, they take brutal measures to suppress abortion and help families in villages.

Only in 21 states is the ratio of men and women approximately the same.

Research has shown that the countries of the former Soviet Union are on the list of countries with a predominantly female population.

In these countries, the difference in life expectancy of both sexes is noticeable. For example, in Belarus the average age of men reaches 65 years, and for women about 80. In this regard, Syria is ahead of Belarus, but this is due to a long civil war.

There is a mismatch in the sex ratio among different age categories. For example, in Russia every year boys are born more often than girls, and up to 30 years, the male population predominates. But closer to the age of 40, the number of women is growing. Each year, this ratio gap becomes larger.

Researchers believe that historical events influenced this difference. The census of people of those times shows that, since the 1900s, 99 men in Russia correspond to 100 women.

Since 1917, the number of women continued to grow on the territory of the Soviet states, then it was influenced by famine and the Stalinist repressions. So, by 1940, there were only 92 men for every 100 women. After 1945, the difference in the ratio increased, the number of men fell to 82. An even smaller percentage was observed in Ukraine, where the indicator was 80. By the beginning of the 21st century, the level had grown, and there were 90 men per 100 women in the USSR.

The reason for the equal sex ratio in the world

Despite wars and other cataclysms, the ratio of men and women in the world has always remained approximately the same. It is not yet possible to name the exact reasons for this phenomenon, but scientists suggest that this is influenced by the need to preserve the human race, for which it is important to maintain the sex ratio in balance.

The population of the Earth is a quantity that is in constant dynamics. The number of people is constantly changing: someone is born, and someone dies. Despite this, the ratio of men and women is practically unchanged, due to the constancy of the species.

It is very interesting to imagine the entire population of the planet as a single group and to see the proportion of women in this group. It is known that almost everywhere more boys are born than girls. It is also no secret that boys often do not live up to adulthood. Does this situation affect the sex ratio?

What is the situation with conception

Studies by demographic scientists in different periods have shown that girls are less likely to delight in the birth of young parents. The sex ratio at birth is played out by the female sex with a score of 51:49. And although the difference is not great, on a global scale it forms a significant preponderance.

Despite the fact that it was previously believed that female embryos die more often during intrauterine development, embryologists have proven that this is not true. That is, during conception, it is the sperm with the Y chromosome that more often penetrate the egg cell. Why this is happening, at the moment there is no definite answer.

The fact is that from the point of view of evolution, it is the female organisms that are important for procreation, since they have a limited reproduction reserve. Even a thousand times fewer men would be fine for humanity. Where and why the sperm with Y-chromosomes are in such a hurry is not yet known exactly.

Slow and nimble sperm

The speed of advancement to the ovum in "female" and "male" spermatozoa is very different. X-spermatozoa move at a low speed, as they are larger, but their vitality is much higher than that of the other group. They can move along the fallopian tubes for a very long time, and if necessary, they can patiently wait for ovulation for about 3 days.

Y-chromosomes have a completely different character: they run rapidly, but because of this, their energy reserves are very quickly depleted, so they are capable of only a single jerk, after which they quickly die.

There is another interesting pattern that has been repeatedly confirmed: for the development of boys, more calories are needed, since their intrauterine growth in early pregnancy is much faster. Therefore, women who eat more high-calorie foods before conception have a greater chance that pregnancy with a boy will not be interrupted in the very first days. Most often, spontaneous abortions occur at a time when the potential mother does not even know that fertilization has occurred.

It has been noticed that during periods of great hunger, an overwhelming number of babies are born. For example, this situation occurred during the famine in China (1951-1960s), which was noted by demographers.

After birth

In infancy, nature, for unknown reasons, does not spare girls: in the first months of life, one third more of them die from any diseases than boys. Even diarrhea is fatal for them 2 times more often.

In the same way, sudden death syndrome (apnea), which scares all the parents of the planet, affects the female sex much more often in infancy.

But from the moment when life begins to depend at least a little on behavior and personal conscious choice, the picture changes dramatically. Starting from the age of two, boys often suffer from rash acts, often act recklessly and persist in trying to prove to the whole world that they are fearless. It is for these reasons that the sex ratio evens out before the end of adolescence.

Girls are more circumspect, they pay much more attention to safety issues. In addition, in no culture is it considered shameful if a baby is scared, which cannot be said about little men. Therefore, social pressure also indirectly affects the behavioral stereotypes of the sexes.

Exact data

The latest official population data was obtained in 2017. Then the population of the planet was 7.3 billion people. Since then, technical calculations have been carried out, according to which 47.6% (3.62 billion) of women and 50.4% (3.68 billion) of men currently live on Earth.

This is due to the fact that there is a large artificial bias in Asian countries: there are much fewer women there.

Where can a Chinese get a wife

In China and India, the practice of selective abortion has been widespread for several decades. After it turns out in the early stages that the fetus is female, an abortion is done. This is due to cultural characteristics, since in these countries the birth of the first male child is considered a great success and pride of the family, which cannot be said about the birth of babies.

This phenomenon - “gendercide” - has long acquired appalling proportions and distorted the demographic picture to the point of absurdity. The current situation has created the prerequisites for the fact that in 2020-2030 every fifth resident of Asian countries will not be able to get a wife and children due to the shortage of women. How many problems this situation brings - it's scary to even imagine. Experts are sure of one thing: the stability and economy of the country due to the lack of women is in a zone of great risk.

Life span

As you know, the life expectancy of women is much higher, which also affects the sex ratio. The peak of female mortality begins at age 50, while for men this age is 2 times less - 25 years.

These indicators are due to the fact that women are less likely to excessive use of alcohol, drugs, cigarette smoking and other bad habits. They take better care of themselves and their health. In addition, the body of every woman of childbearing age gets rid of a large amount of toxins every month during menstruation, and the male sex is deprived of this opportunity.

The life expectancy of women is often influenced by the policies pursued in society. At the moment, it is almost impossible to find a country on the map where men would be treated as dismissively as women are treated in a huge number of places. In most Arab and African countries, livestock is valued much more than a wife, her killing is considered commonplace, and no one will even think of being tried for him.

Nevertheless, among the old people of the planet, the overwhelming majority belongs to the fair sex, therefore, old age on Earth has a female face.

Even at the age of 40, women make up approximately half, but by the age of 60, their number becomes predominant and reaches 54%. Among centenarians who have crossed the 100-year mark, the female sex makes up more than 81%.

Most older women tend to live alone, while men tend to while away their days with their wives.

How many women and men on earth

In the conditions of modern statistics, it is quite easy to figure out who is more - men or women. Today, enough material has accumulated on this issue. Experts monitor the graph of changes in fertility and mortality of the sexes and, based on the findings, form statistics. Of course, research indicators may not 100% reflect the real state of affairs, some conclusions are approximate, but the general base allows us to draw conclusions about who is more in the world - men or women.

Let's start with the main question: who is more often born - boys or girls? The fact is that in the world, regardless of the location of the country, its climate and race of the population, 5% more boys are born. However, due to constant wars, stress and large-scale disasters, men die more often.

Scientists have found an interesting relationship: it turned out that the lower the population size, the more males are born. Today it is observed in some marine species and plants.

In 2010, she answered the question of who is more, men or women, in Russia. According to statistics, it turned out that the total number of citizens living in the territory of the Russian Federation is more than 142 million people. Of these, the female population is 53%. Thus, it turns out that there are fewer men in our country. If we compare the percentage according to the age of the population, then the picture of the high mortality rate of the male population is clearly drawn. The older the age, the more often men die.

On the scale of Russia, the female population not only dominates, but already suppresses the male population. The reason for this is the high female life expectancy. Scientists answer the question of who is more, men or women in the world. According to their research, seven main reasons for the quantitative superiority of women have been identified. The first is special genetics. Further, it is believed that a woman is more emotional, therefore she experiences difficulties more easily, while in life she is more careful. As a rule, men take on important decisions. Due to the enormous responsibility, their body is in constant stress.

Thus, examining the question: "Who is more - men or women?", We can conclude that nature itself sacrifices the male population for the rapid renewal of generations. Therefore, you should not think that a man will endure everything on his mighty shoulders. If so, then his life will be short-lived.

Have you ever thought that if all the inhabitants of the planet stand in one row and join hands, then the length of this line will exceed the length of the equator? And how many women are there on earth and what share does the beautiful half of humanity take in this chain?

Man is an "animal" (mammal), i.e. an animal whose mission is to reproduce. From this it follows a logical conclusion that females and males should be approximately equal. If we take into account the purpose of the species (be fruitful and multiply), then women should prevail. Is it so?

This is not true at the moment. According to the counter of the population of the Earth, for 2016, in percentages:

• , i.e. 3.68 billion;
• women - 49.6%, i.e. 3.62 billion.

This is an average based on a rough addition of the citizens of all countries in the world. In the states themselves, the sex ratio is very funny:

• in Russia, the USA and Central and South Africa, girls lead;
• in the eastern countries and North Africa, the boys win.

The beautiful half of humanity occupies a leading position during periods of wars and political conflicts, which is explained by the high mortality rate of male soldiers.

Why can't you give an exact answer?

It is impossible to calculate the exact number of people inhabiting the Earth, since every moment of time someone is born and dies. Over the next minute (and about as long as you need to read this section), about 100 people will die. During the same minute, 150 human individuals will have time to be born, and one of the women in labor will die.

Of those hundreds that are doomed to die:

• 10 people will be heavy smokers;
• 11 will lose their lives due to malnutrition;
• six will be AIDS carriers;
• 1 will become a victim of a robber or rapist;
• all the rest, except one, will die from other causes (accidents, illness, old age).

That last one will consciously go into oblivion. According to published statistics, this happens every 40 seconds.

According to the census at the beginning of 2016, 7.3 billion people live on the planet. Plus those who escaped the census, live on false documents, or in remote places where government agencies cannot reach.

Why are there more women?

The main premise is a peak in mortality, that is, a high probability of death. For the female half, this is 50 or more years. For men - 25 years old. Such a difference in indicators is explained by the propensity of the stronger sex to alcoholism, drug addiction, other bad habits, as well as hard physical work.
