Population of the world… What associations do everyone who hears this phrase have? Huge globe - how many of us are on it? Who is more: men or women? What is the average life expectancy of a person? How many earthlings are born and die per day? And a year?
We are all people living on this planet. Paying a little more attention to some questions, you can discover amazing information. Did you know that every 0.24 seconds another baby is born on our planet, and in an hour the world population is replenished by more than 15 thousand newborns. And almost every minute (0.56 sec.) a person dies, and in an hour our world loses almost 6.5 thousand people.
Life expectancy is a separate issue. An ancient person was considered a long-liver if he lived to be 35 years old. Thanks to rising living standards and advances in medicine, only in 1950 did the average become 46 years old, and by 1990 it was already 62.
In today's Japan and Scandinavian countries, men live an average of 80 years, women - 75, but the population of the poorest countries in Africa and Asia is unlikely to ever be able toboast of such an age: 47 years - this is the average life expectancy. And Sierra Leone, unfortunately, with a duration of 35 years, has completely remained at the level of centuries ago.
The world population today is approximately 7.091 billion. Moreover, women and men are approximately equal: 3.576 billion males and 3.515 billion people are ladies of all ages. The male population predominates, but in Russia the opposite is true: for every 1,130 women, there are 1,000 men, which is 53% and 47% respectively.
People unevenly occupied the space of the globe. This is understandable, because for 149 million square meters. km. land accounts for about 16 million square meters. km. uninhabitable glaciers, uninhabited deserts and inaccessible highlands. And how did the population of the world act with the remaining 133 million square meters. km.? Some areas are densely populated, and in some parts not a single human soul can be found.
Half of the world's inhabitants live in cities. By the way, until recently, at the beginning of the 19th century, not a single settlement could boast of a population of 1 million. But by the middle of the 20th century, there were eight cities with a population of five million, and by 2000, almost two dozen cities had become megacities with a number of more than 10 (!) million inhabitants
The world's most populated cities in the top five are Shanghai (Japan), Istanbul (Turkey), Mumbai (India), Tokyo (Japan), Karachi (Pakistan). Huge "hives" in which they live, work, have fun, are born and dierepresentatives of humanity are Mexico City, Bombay, Buenos Aires, Dhaka. What to do, people tend to live in the capitals, because there are more opportunities for self-realization and earnings.
Many people know that the Chinese government has set itself the goal of reducing the birth rate by reducing the "allowed" number of children to a minimum: one family - one child. Violators who had a second baby were fined, they were threatened with eviction to remote areas and other punishments. In overpopulated India, it is desirable to have no more than two children. And all because the population of the countries of the world, or rather, the number of people living in each of them, differs significantly from each other. And the leading positions in this list belong to the aforementioned China and India. The difference is significant: the inhabitants of China - 1.3 billion, India - almost 1.2 billion, in third place by a wide margin of the United States - 310 million. Huge Russia with its "modest" almost 142 million inhabitants is only in ninth place. Tuvalu closes the list - there are 10 thousand in it, and the Vatican - 800 (!) people.
