The population of the Earth is increasing every year. Nevertheless, overpopulation does not threaten our planet. The threat to human existence may be the irrational use of renewable and non-renewable resources.
Are born and die
The answer to the question of how many people in the world, of course, exists. Indeed, in each country a census is periodically conducted . As for the absolute accuracy of the numbers, perhaps one cannot be sure. Because every second in the world someone is born, and someone dies.
According to the report of the German Earth Population Fund, compiled at the beginning of 2014, 7.2 billion people live in the world. This figure exceeds last year's by 80 million: it’s just so much less people lived a year earlier on our planet.
Both on land and at sea
The length of the earth's land is 149 million square meters. km Based on how many people live in the world, they should not be crowded on Earth. However, the world's population is unevenly distributed. It is clear that deserts, glaciers, high mountains are almost uninhabited. But even those places that are suitable for human life are not equally populated by people.
The bulk of the population lives in the northern hemisphere of the Earth. The southern hemisphere accounts for only 10% of the population. The Asian continent is the most inhabited - about 60% of humanity is located there. Australia and Oceania occupy the smallest number of people - only 0.5%.
However, people can live even in the most difficult natural conditions and settle in places inaccessible to all. For example, 0.1% of the population is located in endless subarctic and arctic spaces. About 2 million people climbed into the highlands of Tibet, the Pamirs, and the
Ethiopian Highlands (above 3600 m above sea level).
Planet population by countries
In total there are 196 countries on Earth. True, this is only recognized by all, and there are still countries that are not recognized and dependent territories. It is interesting to know not only how many people live around the world, but also the population of which countries is the largest.
So, China, India, the USA open the first ten of the largest countries by the number of countries, followed by Indonesia, Brazil, and Pakistan. It is completed by Bangladesh, Nigeria, Russia and Japan.
Today, more than 1 billion 300 million people live in China. Another billionaire country is India (more than 1.1 billion people). In third place, the United States is still seriously behind the leaders: 310 million people. Russia is now in 9th place with a population of 143 million people.
If there are countries with the largest population, then there are the smallest. These include: Vatican (less than a thousand people), Nauru, Tuvalu, Palau, San Marino, Monaco, Liechtenstein.
Where is the closest?
Many can answer this question without hesitation: China and India. But they will be wrong. These countries are not in the first places in the list of the most populous countries. Although India is in the top twenty (the average population density is 357 people per square kilometer).
The most populous country on the planet is the tiny principality of Monaco. About 16 thousand people live there per square kilometer. Monaco is followed by Singapore and the Republic of Maldives. Of course, these countries belong to mini-states, but statistics are statistics. To the first three you can add the Vatican, Malta and Bahrain.
However, if we take all the same large states, then among them Bangladesh is among the most populated (1,084 people per sq. Km).
The lowest population density on Earth in Mongolia, where fewer than two people per 1 sq. M. km
The population of planet Earth is growing
The process of population growth on Earth is not interrupted. There is even evidence of how it has been going since the beginning of our era. Then, about 175 million people lived on Earth. By the end of the first millennium AD e. they became about 275 million, by 1800 this figure reached almost 1 billion, and after another hundred years - 1.6 billion. 1960 recorded a world population of 3 billion people, 1993 - within 5.6 billion .
In the past 15 years, the number of people on earth continues to increase: 1999 - 6 billion, 2006 - 6.5 billion, 2010 - 6.8 billion. How many people live in the world now, we have already said. Demographics predict that by 2050 about 9.2 billion people will live on Earth.
Interestingly, until the 70s of the last century, the population grew according to a hyperbolic law, and in recent years there has been a slowdown in growth.
Employees of the German Earth Population Fund note that the planet owes an increase in the number of people to developing countries.
The highest population growth occurs in countries such as Burundi, the United Arab Emirates, Niger, Kuwait (more than 3.5% per year). Europe cannot boast of such indicators. On the contrary, there are countries where the mortality rate exceeds the birth rate. With a minus indicator of population growth in the world, there are 25 countries. Among them are Germany, Italy, Russia, Belarus and others.
This is how statistics on the topic look like: “How many people live in the world?”
