The population of the world ... What associations arise in everyone who heard this phrase? The huge globe - how many of us are on it? Who is more: men or women? What is the average life span 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 issues, 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's 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 man was considered a long-liver, if he lived to be 35 years old. Thanks to an increase in the standard of living and the achievements of medicine, only in 1950 the average figure was 46 years old, and by 1990 it was already 62.
In today's Japan and the countries of Scandinavia, men live on average 80 years, women 75, but the population of the poorest countries in Africa and Asia is unlikely to ever boast of such an age: 47 years is the average life expectancy. And Sierra Leone, unfortunately, with a duration of 35 years, remained completely at the level of centuries ago.
The world population today is approximately 7.091 billion. Moreover, women and men are approximately equally divided: 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: 1,130 women account for 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 unsuitable for life glaciers, uninhabited deserts and inaccessible highlands. And what about the world's population did with the remaining 133 million square meters. km.? Some areas are populated with great density, and in some parts you cannot find a single human soul.
Half of the inhabitants of the globe live in cities. By the way, more recently, in 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 the year 2000 almost two dozen cities had become megalopolises with the number more than 10 (!) million inhabitants
The most populated cities of the world, included in the top five, are Shanghai (Japan), Istanbul (Turkey), Mumbai (India), Tokyo (Japan), Karachi (Pakistan). The huge "beehives" in which live, work, have fun, are born and die the multimillion-dollar representatives of humanity, these 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 earning.
Many people know that the Chinese government has set a goal of reducing the birth rate, 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, is significantly different from each other. And the leading positions in this list belong precisely to the aforementioned China and India. The difference is significant: Chinese people - 1.3 billion, India - almost 1.2 billion, in third place with a wide margin of the United States - 310 million. Huge Russia with its "modest" almost 142 million inhabitants is only in ninth place . The list is closed by Tuvalu - it numbers 10 thousand, and the Vatican - 800 (!) People.
