Every moment on earth someone dies or is born.Because to say exactly how many people live in the world right now, at this moment, it is impossible.Although the approximate number of installed.Even created a script - a special robot to calculate the number of people on Earth at the moment.Asked how many people live on the planet Earth in January 2014, he is responsible - 7.189 billion. This is confirmed by the calculations of modern statistics.
Once a person has learned to think, write and calculate, he wanted to count the population and determine how many people in the world.Even in the era of civilization we carried out the first calculations.Makes it the powers to control the payment of taxes.Considered the population in the city, county, country.Census developed difficult and slow.Demographers say that in the world lived a billion more in the 19th century.The number again approx.All the figures on population based on mathematical calculations and assumptions.Over the past two centuries, an increase of 600%, ie more than 6 billion. However, these figures relate to the civilized countries where the birth rate is taken into account.How many people in the world really is hard to say.
first more or less precise data were obtained in 1960, after the census by most countries.Today this figure has exceeded 7 billion.And as it turned out?By adding the number of people from different countries.However, if each State is responsibly for the census?For example, a country like Ukraine, European and civilized like, three times already carries the census due to lack of funds.Statisticians say that only a small percentage of the population account for unreported.For lack of a better we have to agree.
question, how many people in the world born in the history of mankind, in 2008 was named the most interesting of all, proposed a popular magazine "Network."Many scientists have worked on it, and received a variety of figures.Peter Grunwald, an expert Center for Mathematics and Computer Science in the Netherlands averaged 107 billion, and a demographer Carl Haub of the Population Reference Bureau (PRB - Population Reference Bureau) gives the figure 108 billion people.Takeoff is not very big.If we accept these data, now inhabiting the planet make up only 6% of those who lived before.The calculation was performed with 50 000 BC.e., the advent of homo sapiens.For the 1st year n.e.Worldwide lived for 300 million people.In 1650-m has reached half a billion people, and in the 19th century - a billion.
How many people in the world now, we already know.Therefore, the history of the total population of the planet Earth is 108 billion people.It turns out that now the saying is true elegant ancient Romans of the departed to another world: "He's gone to the majority."
Scientists suggest that in 2025 the world will have more than 8 billion people in 2050 - 9.7 billion. Despite all the dire predictions about the future, I want to believe that mankind, show all your significant developmentmargin, has not yet exhausted its resources.According to SP Kapitza, our planet is able to feed and 15, and 25 billion.When the demographic transition is complete, the Earth's population will be able to balance well below the critical value.
