Every moment on Earth someone dies or is born.Therefore, it is impossible to say exactly how many people live on Earth right now, at this minute. Although the approximate number is set. They even created a script - a special robot to calculate the number of people on Earth at the moment. On the question of how many people on planet Earth live on January 2014, he answers - 7.189 billion. This is confirmed by calculations of modern statistics.
Once a person has learned to think, calculate andwrite, he wanted to count the population and find out how many people on Earth. Even in the era of civilization, the first calculations were carried out. The authorities were doing this to control the payment of taxes. Considered the population in the city, county, country. The census was developed difficult and slow. Demographers say a billion lived on Earth back in the 19th century. The number is again approximate. All population figures are based on mathematical calculations and assumptions. Over the past two centuries, the increase was 600%, that is, more than 6 billion. However, these figures relate to civilized countries, where fertility is taken into account. How many people on Earth are real, it's hard to say.
The first more or less accurate data was obtained in1960s, after the census of the majority of countries. Today this figure has exceeded 7 billion. And how is it received? By adding the number of people in different countries. However, does every state treat the census with full responsibility? For example, a country such as Ukraine, such as a European and civilized one, already carries the census three times due to lack of funds. Statisticians believe that only a small percentage of the population is unaccounted for. In the absence of better, you have to agree.
The question is how many people on Earth were born for the wholehistory of mankind, in 2008 was named the most interesting of all proposed by the popular magazine "Quest". Many scientists worked on it, and the numbers were very different. Peter Grünwald, a specialist at the Center for Mathematics and Computer Science in the Netherlands, counted 107 billion, and demographer Karl Haub from the Population Reference Bureau (PRB - Population Reference Bureau) gives a figure of 108 billion people. The takeoff is not very big. If we accept these data, then the people who inhabit the planet now constitute only 6% of those who had previously lived. The calculation was carried out from 50 000 BC. e., the moment of appearance of homo sapiens. By the 1st year n. er around the world already lived 300 million people. In 1650, the population reached half a billion, and in the 19th century, a billion.
How many people on Earth now, we already know.Consequently, in the entire history of existence, the total population of the planet Earth is equal to 108 billion people. It turns out, and now the elegant statement of the ancient Romans about those who have gone into another world is true: “He has gone to the majority”.
Scientists suggest that in 2025there will already be more than 8 billion people on Earth, and in 2050 there will be 9.7 billion. Despite all the terrible predictions about the future, I want to believe that humanity, which has shown a significant margin of safety with all its development, has not exhausted its resources. According to S. P. Kapitsa, our planet can feed 15 and 25 billion people. When the demographic transition is over, the world's population will be able to balance at a level well below the critical one.
