Every moment on Earth someone dies or is born. Therefore, it is impossible to say exactly how many people on Earth live right now, at this moment. Although the approximate number is established. They even created a script - a special robot for calculating the number of people on Earth at the moment. When asked how many people live on planet Earth as of January 2014, he answers - 7.189 billion. This is confirmed by calculations of modern statistics.
As soon as a person learned to think, calculate and write, he wanted to count the population and find out how many people there are on Earth. Even in the era of the development of civilization, the first calculations were carried out. The powers that be did this to control the payment of taxes. The population was counted in the city, county, country. The census developed slowly and difficultly. Demographers say there were a billion people on earth as early as the 19th century. Again, the number is approximate. All population figures are based on mathematical calculations andassumptions. Over the past two centuries, the increase has amounted to 600%, that is, more than 6 billion. However, these figures relate to civilized countries, where the birth rate is taken into account. How many people on Earth is real, it is difficult to say.
The first more or less accurate data were obtained in the 1960s, after the census of most countries. Today this figure has exceeded 7 billion. How is it received? By adding the population of different countries. However, does each state take full responsibility for the census? For example, a country like Ukraine, which seems to be European and civilized, has already postponed the census three times due to lack of funds. Statisticians believe that only a small percentage falls on the unrecorded population. For lack of a better one, I have to agree.
The question of how many people on Earth were born in the history of mankind, in 2008 was named the most interesting of all proposed by the popular Quest magazine. Many scientists worked on it, and the numbers were very different. Peter Grunwald of the Center for Mathematics and Informatics in the Netherlands puts the figure at 107 billion, while demographer Karl Haub of the Population Reference Bureau (PRB) puts the figure at 108 billion. The run is not very big. If we accept these data, then the inhabitants of the planet now make up only 6% of those who lived before. The calculation was carried out from 50,000 BC. e., the moment of the appearance of homo sapiens. By the 1st year. e. There are already 300 million people around the world. In 1650 the population reached half a billion, and in the 19thcentury - billion.
How many people on Earth now, we already know. Therefore, in the entire history of existence, the total population of the planet Earth is 108 billion people. It turns out that the elegant saying of the ancient Romans about those who have gone to another world is still true: “He went to the majority.”
Scientists suggest that in 2025 there will already be more than 8 billion people on Earth, and 9.7 billion in 2050. Despite any terrible predictions about the future, I want to believe that humanity, which has shown everyone its development a significant margin of safety, has not exhausted its resources. According to S. P. Kapitsa, our planet is capable of feeding both 15 and 25 billion people. When the demographic transition is over, the world's population will be able to balance well below the critical level.
