How many people on Earth was, is and will be

Every moment on Earth, someone dies or is born. That's why it's impossible to say exactly how many people on Earth live right now, at this moment. Although the approximate amount is set. Created even a script - a special robot to calculate the number of people on Earth at the moment. When asked how many people on the planet Earth live in January 2014, he answers - 7.189 billion. This is confirmed by calculations of modern statistics.

Once a person learned to think, calculate and write, he wanted to calculate the population and find out how many people on Earth. Even in the era of the development of civilization, the first calculations were carried out. Did it power to control the payment of taxes. They counted the population in the city, county, country. The census was developing slowly and slowly. Demographers say that on Earth lived a billion in the 19 th century. The number is again approximate. All figures about the population 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 were obtained in the 1960s, after the census was carried out by most countries. Today, this figure exceeded 7 billion. And how is it obtained? By adding the number of people in different countries. However, does every state take with full responsibility to the census? For example, a country like Ukraine, such as European and civilized, has already suffered a census three times due to a lack of funds. The statisticians believe that only a small percentage falls on the unregistered population. In the absence of the best you have to agree.

The question, how many people on Earth was born in the history of mankind, in 2008 was named the most interesting of all, offered 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 the demographer Carl Haub of the Population Reference Bureau (PRB) gives a figure of 108 billion people. Race is not very big. If we accept these data, then today the inhabiting planet is only 6% of those who lived before. The calculation was carried out from 50,000 BC. E., The time of the appearance of homo sapiens. By the 1st year of n. E. There were already 300 million people worldwide. 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, for the whole history of existence the total population of the planet Earth is 108 billion people. It turns out, and now the elegant saying of the ancient Romans about those who left the world is different: "He went to the majority".

Scientists suggest that in 2025 there will already be more than 8 billion people on Earth, and in the year 2050 - 9.7 billion. Despite any terrible predictions about the future, I want to believe that humanity, which by its entire development has shown a significant margin of safety , Has not exhausted its resources. According to SP Kapitsa, our planet is able to feed 15 and 25 billion people. When the demographic transition is over, the Earth's population will be able to balance at a level well below the critical level.
