Some statistics. Just 14 years ago, the world community celebrated its anniversary - on Earth on October 12, 1999, a six-billionth inhabitant of the planet was born. This was a whole event, because even a hundred years before that, the world 's population was only 1.9 billion people.
You ask,
how many people live on Earth now? To begin with, we will determine the basic concepts. What is the world's population? This is a constantly updated collection of people who constantly reside in a certain territory. In our case, these are all those people who inhabit the planet at the moment.
Of course, it is impossible to calculate, to the accuracy of a person, how many people on Earth are at a given moment. This can be done only after collecting all the information about the population growth and decline. And the notorious six billionth resident, too, most likely, was chosen very conditionally, based on forecasts. Such forecasts, as well as the question of how many people on Earth, are engaged in such a science as demography. Scientists constantly collect and process information about how many people were born, how many died, what migration processes take place in a particular country, and other data on the quantitative composition of the population from the whole planet to a single street in your city.
According to the data of this science, as early as the beginning of our era, only 300 million people lived on Earth. In general, the population growth even before the 70s of the twentieth century went along a hyperbole, that is, steadily increasing, but after that a gradual decline in population growth began. Thanks to demographics, now everyone can find out not only
how many people are on the planet now, but also how many people lived, for example, in the Middle Ages. Or how the number of people has changed from the end of the first millennium to the present day.
In addition, thanks to statistics and demographics, you can still find out the reasons why the population was growing or, conversely, slowing down its growth. Did you know that between the year 1000 and 1500 the population growth amounted to only 100 million people. And the reasons for this were periods of drought all over the world, the spread of plague, cholera and other diseases incurable at that time, as well as the lack of sanitary hygiene.
And yet, you say, all this is interesting, but where is the answer to our question, how many people live on Earth today? According to the latest data provided by world statistics, as of June 16, 2013, the population of all people on the planet amounted to 7.01 billion people. And for the first time since 2009, the number of citizens is equal to the number of rural residents. That is, in the twenty-first century for the first time in the history of mankind, the number of people living in cities has become the same as those who live in rural areas.
Little conclusion
Now you have received the answer to the question of how many people on Earth live today. If you want to know more, read more literature on demography - this science is interesting and informative for everyone who is interested in how human civilization develops, and by what laws its development is going on.
