Some statistics. Just 14 years ago, the world community celebrated its anniversary birthday - on October 12, 1999, the six billionth inhabitant of the planet was born on Earth. It was a whole event, because even a hundred years before the world's population was only 1.9 billion people.
You ask, how many people live on Earth now? First, let's define the basic concepts. What is the population of the earth? This is a constantly updated set of people who constantly live 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 nearest person how many people are on Earth at a given moment. This can be done only after collecting all the information about the increase and decrease in the population. 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 are on Earth, are de alt with by such a science as demography. Scientists are constantly collecting andprocess information about how many people were born, how many died, what migration processes are taking place in a particular country and other data on the quantitative composition of the population from the entire planet to a single street in your city.
According to this science, at the beginning of our era, only about 300,000,000 people lived on Earth. In general, even before the 1970s, population growth was hyperbole, that is, steadily increasing, but after that, a gradual attenuation of population growth began. Thanks to demography, 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 increased or, conversely, slowed down its growth. Did you know that between the year 1000 and 1500 the population growth was only 100 million people. And the reasons for this were periods of drought around the world, the spread of plague, cholera and other diseases that were 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 total of all people on the planet amounted to 7.01 billion people. And for the first time since 2009, the number of urban residents is equal to the number of rural residents. That is, in the twenty-first centuryFor the first time in human history, the number of people living in cities has become the same as those living in rural areas.
Small conclusion
Now you have received the answer to the question of how many people live on Earth 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 what laws it develops.
