Every moment on Earth, someone dies or is born. Therefore, to say for sure how many people on Earth lives right now, at this moment, is impossible. Although the approximate amount is set. They even created a script - a special robot to calculate the number of people on Earth at the moment. When asked how many people on planet Earth live in 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 are on Earth. Even in the era of civilization, the first calculations were carried out. Those in power did this to control tax payments. Counted the population in the city, county, country. The census has evolved hard and slow. Demographers say a billion people 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, growth has amounted to 600%, that is, more than 6 billion. However, these figures apply to civilized countries where birth rates are taken into account. How many people on Earth are real, it's hard to say.
The first more or less accurate data were obtained in the 1960s, after the census of the population by most countries. Today, this figure has exceeded 7 billion. And how is it received? By adding up the population of different countries. However, is each state fully responsible for the census? For example, a country such as Ukraine, like a European and civilized one, has already endured the census three times due to lack of funds. Statisticians believe that only a small percentage falls on the unaccounted population. For want of a better one has to agree.
The question of how many people on Earth was born in the entire history of mankind was called the most interesting of all proposed by the popular Quest magazine in 2008. Many scientists worked on it, and the numbers received are very different. Peter Grunwald, a specialist at the Center for Mathematics and Computer Science in the Netherlands, counted 107 billion, and demographics Karl Haub of the Population Reference Bureau (PRB) provides 108 billion people. The run-up is not very large. If we accept these data, then the inhabitants of the planet 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 of AD e. 300 million people have lived around the world. 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 its existence, the total population of planet Earth is 108 billion people. It turns out, and now the elegant saying of the ancient Romans about those who have gone to another world is 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 a significant margin of safety with all its development , has not exhausted its resources. According to S.P. Kapitsa, our planet is able to feed both 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 level.
