Counting earthlings is not done out of simple curiosity. For a normal life, each of us needs a certain amount of water, air, minerals, and food. In turn, each of the inhabitants of the Earth influences the environment. Therefore, it is very important to know how many people live on our planet.
In order to find out how many people live on Earth, you need to identify their number in individual countries and regions of the planet.
In most countries, population is determined using general population censuses. They are carried out regularly once every 5 or 10 years. But in some countries and areas of the world, censuses have either not been conducted at all or have been conducted for a very long time.
Therefore, the total world population is determined using special calculations.
How many people are there now?
There are currently just under 7.4 billion people living on Earth.
For many millennia, the number of people on Earth was small and did not increase very quickly. But since the 19th century. rapid population growth began, which continues to this day.
What influences the growth of human numbers?
The growth in the number of people depends on many reasons.
This includes the level of development of the country, the well-being of people, and national traditions. Until now, the reasons for changes in the number of people on the planet remain hunger, disease and war, as well as natural disasters.
The change in population size is determined by the ratio of birth rates and deaths.
World population by year
Currently, 21 people are born and 18 die every second in the world. As a result, the world's population is growing by 250 thousand people every day. But in different periods of human history and in different regions of the Earth, the magnitude of population growth is not the same.
The average age of the inhabitants of these countries also depends on the state of fertility and mortality in different countries. Countries with high population growth have many children and young people.
Countries with low growth have a high proportion of older people.
The age of a country's inhabitants and population growth are largely determined by life expectancy, which, in turn, depends on the country's level of development. In developed countries, life expectancy and the average age of residents are high, and population growth is generally low.

Population growth
Population growth is very rapid (Table 1).
Every year the world population increases by 60-80 million people.
Human. The population is expected to reach 8 billion and 2100-11 billion by 2024.
Population density
Population density shows the average number of inhabitants per 1 square. Km. km. To determine world population density, population must be divided by land area.
In 2013, every square kilometer of land contains an average of 52 people.
In terms of the number of countries with the highest population density, the South Asia region leads the way, followed by Europe.
There are no permanent residents in Antarctica.
Acceleration of the planet
Some scientists are studying the death of humanity from overpopulation. “Such a large number of inhabitants,” they say, “cannot feed the earth.”
Among them there are those who believe that humanity will save wars from overpopulation, epidemics of various diseases, they can take millions of human lives in a few minutes. Of course, humanity does not want wars; it will not allow an epidemic of diseases in our time. Material from this site http://wikiwhat.ru
Modern scientists all over the world scientifically prove that the death of overage people is not at risk in the world, so that the earth can feed billions of people.
But in fact, humanity currently only processes about 10% of the surface.
Population growth: from 10,000 years to our count. until 2100
But even if this 10% now grows the area, if the increase in food supply has already been achieved in many developed countries, 9 billion worth of food can be obtained. Human, but if you change the food and feed all the vegetation, the annual yield of these crops can be stored for more than 50 billion people.
Even with the use of modern technology, we can double the amount of land available for cultivation and in the future, with the advancement of science and technology, there is practically no country on our planet suitable for agricultural use.
People leave the swamp, irrigate the deserts, and bring in frost-resistant and fast-growing varieties of crops.

RULES OF ETIQUETTE
Etiquette is the form, manner of behavior, rules of courtesy and politeness accepted in a particular society. The practical significance of etiquette is that it enables people to effortlessly use ready-made forms of generally accepted politeness to communicate with different groups of people and at different levels.
The basics of etiquette are quite simple.
Of great importance for people’s communication is their appearance, clothing, and the ability to behave correctly in public places and in various situations.
A good impression is made by a well-dressed, polite person who knows how to behave in any circumstances and always behaves accordingly.
The manner of speaking and the ability to maintain a conversation are also of no small importance when people treat each other. In order to be a good conversationalist, you need to know what you are talking about and be able to express your thoughts in such a way that they are interesting to others.
The ability to manage your negative emotions indicates good manners and good manners.
According to etiquette, the best way to overcome irritation and dissatisfaction in yourself and others is to smile.

More than 107 billion people were born on Earth during the entire history of mankind, which began 162 thousand years ago, calculated Peter Grunewald, a statistician at the Dutch Center for Mathematics and Informatics.
According to his calculations, commissioned by the monthly magazine Quest, the 6.7 billion people living on our planet make up 6% of all people who have ever lived on it.
Population of the Earth
Grunwald admits that this figure (107.5 billion people) cannot be absolutely certain because little or nothing is known about population and fertility in ancient periods of history. At the same time, the researcher considers incorrect the statement of some scientists that there are more people living on Earth now than in the entire history of mankind.
The question “How many people have been born on Earth in the entire history of mankind?” was voted the most interesting question of 2008 out of 101 questions proposed by Quest magazine.
This opinion was reached by the jury formed by the magazine, which included, in particular, the Dutch cosmonaut Andre Kuipers, who flew to the International Space Station on the Russian Soyuz spacecraft, RIA Novosti reports.
Helpful information
Many experts believe that there is currently a threat of overpopulation of the Earth, which will lead to mass famine. It will be aggravated by a global environmental catastrophe. And therefore, urgent measures are needed, thanks to which it would be possible to regulate the number of people.
But before you do anything, you need to ask yourself: how many people can live on Earth?
The same environmental law applies to all living organisms inhabiting our planet. It consists of the following phases, following each other - explosion, crisis, collapse, stabilization. Any living species, once in a favorable environment, sharply increases its numbers. This is an explosion. But a huge number of individuals begin to destroy the habitat.
Therefore, a crisis comes, followed by collapse. It is expressed in a catastrophic decline in population to a lower level than it was originally. During the period of collapse, the environment is restored, and the population size increases to a reasonable level.
After this, stabilization occurs. Humanity is currently in a phase of crisis.
It should be noted that there are 3 periods of increase in the number of people. The first period dates back to the end of the Pleistocene (2.6 million years ago).
years - 11.7 thousand years ago). It was characterized by the settlement of hunting tribes throughout the globe. The second period was observed 9 thousand years ago, when humanity mastered agriculture. The population of the Earth then increased 20 times. And the third period is associated with the industrial revolution. This process has not died out these days, but is only gaining momentum. At the same time, the Earth's population increased 30 times.
The area of cultivated land increased by 3 times, and productivity by 7 times.
10 million people lived on our planet 10 thousand years ago. By the beginning of our era, there were already 200 million people. By the middle of the 17th century, when the industrial revolution began, the planet was inhabited by 500 million.
Human. At the beginning of the 19th century there were already 1 billion, and at the beginning of the 20th century there were 2 billion. At the beginning of 2016, 7.3 billion people lived on Earth. Every year the population increases by 2%. It took humanity 200 thousand years to reach the first billion. The second billion was achieved in 100 years, and the third in just 40. The fourth billion in 15 years, and the fifth in 10.
Nowadays, humanity doubles every 35 years. And the amount of food doubles every 30 years.
This is the main indicator of our existence. But it does not increase on its own, but due to the development of new lands. And every year it becomes more and more difficult to ensure crop growth. We must also not forget about electricity and water, which are required more and more.
As a result, resources are depleted and the natural environment is destroyed. Reserves of coal, oil, gas, and mineral raw materials are being used to the limit. But these reserves are not renewed in any way.
Therefore, the present unlimited well-being is finite in time.
It will end because the habitat will be destroyed, food production will fall, and after this the population will decrease to the level that the remaining resources can provide.
How many people can live on Earth?
Ecologists answer this question quite definitely, since the biosphere exists according to a simple law. It relates the size of organically consuming species to their numbers.
How many people can planet Earth support?
The main role in the flow of energy and substances is given to small organisms. But the big ones play only a supporting role. Therefore, the main consumers in the biosphere are arthropods, mollusks, and worms.
Wild vertebrates, which include amphibians, reptiles, mammals, and birds, consume only 1% of biosphere production.
A person with domestic animals should be part of the group of wild vertebrates, that is, consume less than 1%. But modern humanity consumes 7% of the biosphere's production. That is, much more than it should be. As a result of this, all biosphere patterns are violated. And how many people can live on Earth?
Here we must understand that the biosphere is a self-regulating system. Therefore, she strives to return the number of people to normal levels. It is 25 times lower than the modern one, that is, about 300 million people. And this is for the entire planet. A maximum of 500 million people can live on Earth, but not 7, 8 or 10 billion. This is why the productivity of valuable ecosystems is falling, animals that people need are dying out, and essential plants are disappearing. All this is connected with the self-regulation of the biosphere, which seeks to limit the number of humanity.
Earth population in millions of people
What will the collapse be like?
A decrease in the Earth's population will certainly occur, since the biosphere will not allow its destruction. But this can happen in different scenarios. First scenario, which still works in some countries, is hunger. Today, only 500 million people on the planet have adequate nutrition, and 2 billion are regularly malnourished.
20 million people die from hunger every year, and the human population during the same time increases by an order of magnitude.
If there are 200 million people dying of hunger per year, then population growth will stop. And if the number of deaths increases further, then the population will begin to decline.
But this is a terrible and inhumane process. It will bring so much grief that it’s even scary to think about.
Second scenario purely political. It is connected with a nuclear disaster. A global conflict over non-renewable resources will begin, and a nuclear war will break out. It is capable of completely destroying all of humanity, leaving only a few intelligent beings on Earth. And then civilization will begin to be reborn in a new way.
And this may take thousands of years.
Third scenario designed for people's awareness. State governments will introduce birth restrictions, which will lead to a decrease in population.
However, this development of events raises serious doubts, since birth control in some countries has not yet led to the desired results.
Fourth scenario connected directly to our planet. To save herself, she can weaken the Earth's magnetic field. In this case, we will find ourselves defenseless against solar plasma. It will burn everything out, but nature will quickly recover, but humanity will be almost completely destroyed. This scenario is similar to a nuclear war, only the Earth itself will be the initiator here.
There are also fifth scenario. In this case, the biosphere will begin to send signals to people on a subconscious level. They will act on the mechanisms responsible for fertility, and humanity will begin to respond to them.
This will be expressed in a natural decrease in population growth, as occurs in many animal species. But here it should be understood that a person has long been cut off from nature, and therefore may not perceive the corresponding signals entering the subconscious. Who knows, maybe they are already coming, but only a few react to them.
In a word, the situation is not very rosy. We learned how many people can live on Earth, and also realized that the current population has long surpassed all norms.
We can only wait for further developments, since this situation cannot continue forever. Let's hope that humanity will painlessly emerge from such a delicate and critical situation.

Planet Earth is home to many living beings, the main one of which is man.
How many people inhabit the planet
The world population today is almost seven and a half billion people. The peak value of its growth was noted in 1963. Currently, the governments of some countries are pursuing a restrictive demographic policy, while others are trying to stimulate population growth within their borders. However, the overall population of the Earth is aging. Young people do not strive to reproduce. The population of planet Earth today has an unnatural bias towards the elderly. This feature will complicate the financial support of pensioners.
According to scientists, by the end of the twenty-first century the world's population will reach the eleventh billion.
Where do the most people live?
In 2009, an alarm bell rang. The world's population living in cities has become equal in size to the number of people living in villages and rural areas. The reasons for this movement of labor are simple. The world's population strives for convenience and wealth. Salaries in cities are higher, and life is simpler. This will all change as the world's urban populations become more food insecure. Many will be forced to move again to the provinces, closer to the land.
The world population table is as follows: Fifteen countries are home to nearly five billion people. In total, there are more than two hundred states on our planet.
Most populous countries
The world population can be presented in the form of a table. The most populous countries will be indicated.

Most populous cities
The world population map today already has three cities whose population exceeded twenty million people. Shanghai is one of the largest cities in China, which stands on the Yangtze River. Karachi is a port city in Pakistan. The Chinese capital, Beijing, closes the top three.
In terms of population density, the palm is held by the main city of the Philippines - Manila. The world population map reports that in some areas this figure reaches seventy thousand people per square kilometer! The infrastructure does not cope well with such an influx of residents. For example: in Moscow this figure does not exceed five thousand people per square kilometer.
Also on the list of cities with a very high population density are Indian Mumbai (this locality was previously called Bombay), the capital of France - Paris, the Chinese autonomy of Macau, the dwarf state of Monaco, the heart of Catalonia - Barcelona, as well as Dhaka (Bangladesh), the city-state of Singapore , Tokyo (Japan), and the previously mentioned Shanghai.
Population growth statistics by period
Despite the fact that humanity appeared more than three hundred years ago, for a long time its development was extremely slow. The short life expectancy and extremely difficult conditions took their toll.
Humanity exchanged its first billion only at the beginning of the nineteenth century, in 1820. A little more than a hundred years passed, and in 1927, newspapermen trumpeted the joyful news of the second billion earthlings. Just 33 years later, in 1960, they spoke about the third.
From this period, scientists began to seriously worry about a boom in the world's population growth. But this did not stop the four billionth inhabitant of the planet from joyfully announcing its appearance in 1974. In 1987, the account reached five billion. The six billionth earthling was born closer to the millennium, at the end of 1999. Less than twelve years have passed since there are a billion more of us. At the current birth rate, no later than the end of the first quarter of this century, the name of the eight billionth person will appear in newspapers.
Such impressive successes have been achieved primarily due to a significant reduction in bloody wars that claim millions of lives. Many dangerous diseases were defeated, medicine learned to significantly prolong people's lives.
Consequences
Until the nineteenth century, people had little interest in the population of the world. The term “demography” was introduced into use only in 1855.
At the moment, the problem is becoming more and more threatening.
In the seventeenth century, it was believed that four billion people could live comfortably on our planet. As real life shows, this figure is significantly underestimated. The current seven and a half billion feel relatively comfortable with a reasonable distribution of resources.
Potential settlement opportunities are possible in Australia, Canada, and desert areas. This will require some efforts for improvement, but theoretically it is possible.
If we take into account exclusively territorial possibilities, then up to one and a half quadrillion people can be settled on the planet! This is a huge number, containing fifteen zeros!
But the use of resources and the rapid heating of the atmosphere will very quickly change the climate so much that the planet will become lifeless.
The maximum number of inhabitants on Earth (with moderate demands) should not exceed twelve billion. This figure is taken from food supply calculations. As the population grows, it is necessary to obtain more resources. To do this, it is necessary to use more areas for sowing, increase the number of livestock, and save water resources.
But if food problems can be solved relatively quickly, thanks to genetic technologies, then organizing the consumption of clean drinking water is a much more complex and costly undertaking.
In addition, humanity must move to the use of renewable energy sources - wind, sun, earth and water energy.
Forecasts
Chinese authorities have been trying to solve the problem of overpopulation for decades. For a long time, there was a program that allowed no more than one child per family. In addition, a powerful information campaign was carried out among the population.
Today we can say that the Chinese have succeeded. Population growth has stabilized and is projected to decline. The growth factor in the well-being of Chinese residents played an important role here.
Regarding the poor in India, Indonesia, and Nigeria, the prospects are far from rosy. In just thirty years, China may lose the “palm” in the demographic issue. India's population could exceed one and a half billion people by 2050!
Population growth will only worsen the economic problems of poor countries.
Current programs
For a long time, people were forced to have a large number of children. Running a household required enormous strength, and it was impossible to cope alone.
A guaranteed pension could help solve the problem of overpopulation.
Also possible ways to solve the demographic issue are thoughtful social policy and reasonable family planning, as well as increasing the economic and social status of the fair half of humanity, and increasing the level of education in general.
Conclusion
It is very important to love yourself and your loved ones. But we should not forget that the planet on which we live is our common home, which must be treated with respect.
Today it is worth moderating your needs and thinking about planning so that our descendants can live as comfortably on the planet as we do ourselves.
Hello readers! We now live in a world where the population is only growing, but just imagine for a second that such a number of people was not always there. I want to tell you about this growth.
The dynamics of the world population are constantly growing; Only in certain, comparatively short historical periods, due to epidemics, natural disasters, and war did it temporarily decrease (for example, about 15 million people died from the plague epidemic in the 14th century; from famine in the 19th century - 25 million people in India and almost as many in China; about 20 million people died from the Spanish flu after the First World War (1914 - 1918); 60 million people died in two world wars, and even more significant were the indirect losses of humanity from increase in mortality and decrease in birth rate).
Over the millennia, the population increased extremely slowly, this can be explained by the poor development of production and the very large dependence of man on Mother Nature in the early stages of history.
The natural environment limited the increase in the number of primitive people, whose basis of life was hunting, fishing and gathering. Until the end of the Paleolithic, according to rough estimates, people mastered less than 1/3 of the modern ecumene (approximately 40 million km 2), and the average hardly exceeded 8 - 10 people per 100 km 2.
Many researchers agree that by the end of the Paleolithic era (approximately 15 thousand years BC), the population reached approximately 3 million people, and by the end of the Neolithic era (2 thousand years BC), the population was approximately 50 million people. There were 230 million people on Earth already at the beginning of our era, until the end of the 1st millennium AD. e.- 275 million people, and before 1500 it increased to 425 million.
Since the 17th century. The rate of world population growth has apparently increased. The rapid rise of agriculture, the increase in industry, and advances in medicine in many Western European countries (XVI-XVIII centuries) affected the population.
Population growth accelerated very quickly from the second half of the 18th century. At this time, the first (of statistically recorded) and extremely strong jump in population growth occurred in individual countries of Western Europe. From 1500 to 1900 The world population has almost quadrupled.
For the second half of the 19th century. Characterized by a particularly rapid acceleration of population growth rates, this is explained by a decrease in mortality, especially among children.
Throughout history, the dynamics of the world population are constantly increasing, and this is evidenced by such data. The population has increased 25 times in the last millennium alone; the first doubling of the population took almost 600 years, the second almost 250 years, the third less than 100 years, and the last just over 40 years.
The population reached 1 billion people around 1820, 2 billion reached 107 years later (in 1927), 3 billion reached 53 years ago (in 1959), 4 billion reached 15 years ago. years (in 1974), 5 billion - reached 13 years later (in 1987).
At the end of 2011, the 7 billionth inhabitant of the planet was born. At the moment, more than 7 billion people live on Earth.
Due to uneven population growth, the share of individual regions in the total world population in the 19th – 20th centuries. has changed a lot. The rate of population growth has accelerated sharply since the middle of the 20th century. The population increased by 116.8% between 1959 and 1992...
Average annual growth in 1950 – 1960 became 53.3 million people, in 1960 - 1970. – 66.7 million, in 1970 – 1980 – 70.3 million, in 1980 – 1990 – 86.4 million, in 1991 – 1992 – 92.2 million. This acceleration in the rate of population increase is different from all previous ones.
During this period, the birth rate changed very significantly. Through natural growth, the population of many countries and even regions (Africa) from 1950 to 1992. more than tripled.
Developing countries.
And in developing countries, life expectancy has increased, but remains lower than in countries with developed economies: in - 53 years, in - 61 years, in Latin America - 67 years.
In developing countries, where about 77% of the world population is concentrated, a decrease in mortality by the early 1990s. was mainly caused by advances in health care rather than by social and economic changes.
The birth rate remains high, especially in rural areas. For example, mortality in Kenya between 1965 and 1969 decreased by half, and in the early 1980s. population growth averaged 3.8% per year. Accordingly, Kenya's population has doubled in less than 20 years.
In developing countries, the proportion of the population under 15 years of age is about 37% and only 4% is over 65 years of age. For comparison, in developed countries, the population under 15 years of age is 22%, and over 65 – 11%.
As a result, developing countries are home to large numbers of children whose contribution to the economy is minimal, but the resources required for their education and health care are significant.
And developed countries must remember the constantly increasing number of pensioners.
Nowadays, there are more than 2 thousand peoples on Earth. The geographical distribution of the population is uneven: according to experts, 70% of humanity lives on 7% of the land mass.
Forecasts.
In developed countries with low population growth, most couples have no more than two children. The population in some countries is declining. For example, in Germany during the 1980s. the population decreased by 0.1% per year.
The use of contraception is encouraged by many developing countries. In the 14 largest developing countries, including India and China, the reproduction rate, measured by the number of children per woman, was . fell by almost two thirds.
In the 1980s in China, growth was reduced to 1.3%, but the target was not achieved. Most Chinese couples want a son to support them in their old age.
Over the next few decades, the general trend remains a rapid increase in the world population, despite falling birth rates. According to UN Population Fund forecasts, the number of people living on Earth was expected to exceed 6.2 billion by 2000, and by 2025 – 8.5 billion.
The pace is then expected to slow, with the global population expected to reach 11.6 billion by 2120. If current efforts to reduce the birth rate prove ineffective, the figure could reach 14 billion.
Obviously, 95% of the growth will occur in poor countries in Asia, Latin America and Africa, which are not able to feed such a number of people. In order to stabilize fertility, the replacement level, which was 4 births per woman in developing countries in 1990, must fall to 2.
Promoting the use of contraceptives is not enough for this. It is necessary to implement economic and social reforms that improve people's living standards.
Thus, we found out that the population is always growing, and the farther it goes, the faster... I mean that our planet is filling up with new people faster than in the past (especially at its initial stage of development). And this is happening despite the fact that population growth has almost halved...
And of course, in this issue, as in many others, there are many opinions, reasoning, many forecasts, including overpopulation; but if the world’s population slows down its growth more, I think at the expense of developing countries, because growth has already decreased at the expense of developed countries, then this will only be beneficial for everyone...
Humanity gravitates towards precise numbers and loves statistics, because sometimes a quantitative change in a phenomenon can indicate important facts. Thus, an increase in average life expectancy indicates an improvement in the level of medical care, access to quality food and clean water, and an increase in the level of living comfort. Dynamic changes in the Earth's population can also tell a lot. How many people live on the planet, what are the population growth trends and what can they lead to?
World population 2018
The number of people on our planet is growing rapidly: on average, the annual global population growth is approximately 75-85 million people, which is equal to the number of inhabitants of a large state. If in 1800 the global population of the Earth numbered about a billion, then by 2012 this figure had reached an impressive 7 billion people.
It is noteworthy that the fastest rates of population growth are observed in countries with fairly low living standards, and not in rich countries with strong economies. This is often due to the insufficient level of education of citizens, the lack of sex education programs and limited access to quality contraception.
In developed countries, both women and men more often give preference to building a career, have children at an older age, and are usually limited to one or two heirs. In economically weak states, completely different priorities dominate among the population; a combination of different factors contributes to higher rates of population growth.
As of 2018, the number of people on the planet exceeded 7 billion 635 million people, as reported by specialists from the German Earth Population Foundation (DSW). Compared to 2017, this figure has already increased by 83 million citizens. The next milestone, 8 billion people, will be reached around 2024. The difference between the number of city residents and residents of rural areas has also become almost equal: if previously the majority of the population lived outside the city, now there is a growing trend in the number of residents of large settlements.
How is the world's population growing?
A number of scientists are of the opinion that the number of inhabitants on the planet is growing according to a hyperbolic law, the essence of which is based on the close and constant interaction of the entire world population. So far, predictions based on this theory are coming true. In 1964, biologist Julian Huxley suggested that by the year 2000 the world population would be 6 billion. His calculations turned out to be accurate and became reality in October 1999.
Why is the constant growth of the Earth's inhabitants dangerous? The inevitable depletion of the planet's resources, rising unemployment against the backdrop of technological development, increasing social inequality and many other negative phenomena can become the reality of humanity and may well serve as the cause of a crisis and catastrophe that will lead to a sharp decrease in the number of people to literally 2-3 billion.
However, gradually the rate of population growth will slow down, giving way to natural depopulation. Already, the number of elderly people exceeds the category of children under 5 years old.
According to UN experts, by 2100 the planet's population will be 11 billion people, and this figure will remain stable.
Earth population density
Population density varies in different places on Earth. Small countries with a high level of development confidently outperform even such “whales” as Russia or China in terms of density. Thus, the states with the largest number of people per square kilometer are Monaco and Singapore, where the number of inhabitants is more than 18.6 and 8.3 thousand people. per sq. km respectively. At the bottom of the list with the lowest population density are Mongolia, Namibia, Australia, Suriname, Iceland and even Canada. Here is the number of residents per square meter. km of territory does not even reach four people. This situation is connected not only with the area of the states themselves, but also with the fact that most of them are unsuitable for life.
Uneven population density on Earth
From a planetary perspective, global population density can be calculated in several ways. If we take into account the area of all continents and oceans, it turns out that every square kilometer of the Earth is inhabited by approximately 15 people. About 51 people per km inhabit the entire land area of the planet, excluding water expanses.
The most populated countries remain China, India and the USA.
Russia is also one of the ten most populated states. The first largest country in the world is inhabited by 144.5 million people, whose population density is 8.56 citizens per square meter. km.
Whatever the forecasts of scientists, it is important for people to remain confident in the future and not lose moral values. After all, it is not technology that makes us human, but humanism and caring attitude towards all living things and our native planet. Such an approach will help us face any difficulties with dignity, even if the Earth's population reaches a critical point.
In contact with
Ukraine is a country with the second largest territory among European countries, located in its eastern part.
General demographic and geographic characteristics
The population is about 43 million. Within our entire planet, this is the thirty-second largest number of inhabitants among all other states. Countries such as Moldova and Romania, Hungary and Slovakia, Poland, Belarus and Russia are its neighbors.
In its southern part, the territory is washed by the Black and Azov Seas. Basically, the area is flat and hilly in places, and only five percent are (with the highest point at 2061 meters - Goverla) and Crimean (highest point - Roman-Kosh, 1545 meters).
Briefly about the wealth of natural resources
Of the one hundred and twenty types of minerals that are known to man and he uses them, 97 are available here. Five percent of the world's reserves - this is exactly the amount of iron ore concentrated in the lands of Ukraine. In addition, there are large deposits of coal, the largest deposits of sulfur in the world, and mercury ores (second place). A huge number of non-metallic minerals are widely used in the construction industry. These are clay, limestone, tuff, marble, basalt, gypsum, chalk, marl. In terms of reserves of table salt, graphite, and kaolin, Ukraine is among the leading countries in the world and Europe in particular. And this is not the entire list of what the Ukrainian land is rich with.
Population concentration
Almost 69% of the population lives in Ukrainian cities, of which there are 460. The remaining 31% falls on the population (885) and rural settlements, of which there are over 28 thousand. In small villages, the main occupation is agriculture, which has all the favorable conditions for development and high productivity. These include climatic conditions and soil quality (a third of the arable land in all of Europe is located in Ukraine). The only thing that is unfavorable is the attitude of some people towards agriculture.
The government pays little attention to this issue, the villagers do not have much support, therefore agriculture is only partially developed on an industrial scale, and grains and corn are developed in the crop sector. Livestock farming is mainly at the level of providing for one's own family. In cities there is a concentration on different types of industry.
Cities that are the largest by area
In terms of area, Kyiv, the capital, is in first place among Ukrainian cities, and its territory is 870.5 sq. km.
The next five cities have about 400 square kilometers, these are Makeevka (Donetsk region), Gorlovka (Donetsk region), Krivoy Rog (Dnepropetrovsk region), Dnepropetrovsk itself and Donetsk. Their areas are 425.7 sq. km, 422 sq. km, 410 sq. km, 405 sq. km. and 385 km sq. respectively. Apart from Kyiv, the largest cities in Ukraine have such a large area due to their highly developed industrial activity. Thus, in Makeyevka there are about twenty factories and factories focused on heavy industry (coal mining, mechanical engineering) and food enterprises. Together with Donetsk, these two cities are the largest hub. Gorlovka has more than fifty different enterprises in the chemical, coal, food, engineering and processing industries. Krivoy Rog is the center of the most important raw material base of metallurgy. Dnepropetrovsk, with its 200 enterprises in thirteen industries, produces 4.5% of all industrial products in Ukraine. As for Kyiv, it is a center not only for industry, but also for other issues, such as politics, culture, science, transport, religion.
In the top ten, which consists of the largest cities of Ukraine by area, there are: in seventh place - Kharkov (350 sq. km), eighth place behind Zaporozhye (331 sq. km), ninth - Lugansk (269 sq. km), and Nikolaev concludes the top ten (253 km sq.).
Which cities have the largest number of inhabitants?
But if the consequences of the above-mentioned catastrophe cannot actually be corrected by anything, then the remaining problems can be solved, the main thing is to make an effort. Continuation of this attitude towards the external environment will soon lead to a critical decline in the population of Ukraine.
