I wonder how many people on Earth?

Some statistics. Just 14 years ago, the world community celebrated its anniversary birthday - on October 12, 1999, a six-billion-strong inhabitant of the planet appeared on Earth. This was a whole event, because even a hundred years before the Earth'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? It is a constantly updated set of people who live permanently in a certain territory. In our case, these are all those people who inhabit the planet at the moment.

Of course, it's impossible to calculate the accuracy of a person, how many people on Earth at a given moment. This can be done only after collecting all the information on the increase and decrease in the population. And the notorious six-billionth resident, too, most likely was chosen very conditionally, based on forecasts. Such predictions, 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 processes of migration occur in this or that country and other data on the quantitative composition of the population from the entire planet to a separate street in your city.

According to the data of this science, at the beginning of our era only about 300,000,000 people lived on Earth. In general, population growth even before the 70s of the twentieth century was on the hyperbole, that is, steadily increasing, but after that the gradual attenuation of population growth began. Thanks to the 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 today.

In addition, thanks to statistics and demographics, one can also find out the reasons why the population increased or, on the contrary, slowed its growth. Did you know that between 1000 and 1500 the population growth was only 100 million people. And the reasons for this were periods of drought all over the world, the spread of plague, cholera and other, incurable at the time diseases, as well as the lack of sanitary hygiene.

And yet, you will say, all this is interesting, but where is the answer to our question, how many people on Earth live today? According to the latest data provided by world statistics, as of June 16, 2013, the total number of people on the planet was 7.01 billion people. And for the first time since 2009, the number of townspeople is equal to the number of rural residents. That is, in the twenty-first century for the first time in human history, the number of people living in cities has become the same as those who live in rural areas.

A small conclusion

Now you have received an answer to the question about how many people on Earth live for 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 the human civilization is developing, and on what laws it is developing.
