Some statistics.Only 14 years ago, the international community celebrated the anniversary birthday - in the world October 12, 1999 was born six billionth inhabitant of the planet.It had been an event, because even a hundred years before the Earth's population was only 1.9 billion. People.
You may ask, how many people live in the world now?To start to define the basic concepts.What is the population of the Earth?It is constantly updated collection of people who reside in a specific territory.In our case - it's the people who inhabit the planet at the moment.
course, calculated up to the person how many people in the world at the moment, impossible.This can be done only after gathering all the information about the growth and decline of the population.And the proverbial six billionth inhabitant is also likely, was chosen rather arbitrarily, on the basis of forecasts.These projections, as well as the question, how many people in the world, engaged in a science, as demographics.Scientists constantly collect and process information about how many people were born, how many died, some migration processes taking place in a given country and other data on the size of the population of the entire planet to a single street in your city.
According to this science, at the beginning of our era in the world lived only about 300 million people.Overall population growth before the 70-ies of XX century was for hyperbole, that is steadily increasing, but then began a gradual attenuation of the population growth.Due to demographics Now everyone can learn not only how many people on the planet now, but how many people lived, for example, in the Middle Ages.Or how to change the number of people at the end of the first millennium to the present day.
In addition, thanks to the statistics and demographics, you can still find reasons for the population increase or, conversely, it slowed its growth.Did you know that between the year 1000 and 1500 the population growth amounted to only 100 million people.And the reason is that there have been periods of drought around the world, the spread of plague, cholera and other incurable diseases at that time, and the lack of health care.
And yet, you say, all this is interesting, but where the answer to our question, how many people live in the world today?According to the latest data submitted by the world statistics, on June 16, 2013 the aggregate of all people in the world was 7.01 billion. People.And for the first time since 2009 the number of citizens 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 was the same as those who live in rural areas.
small conclusion
Now you have the answer to the question of how many people live in the world today.If you want to know more, read more literature on demography - the science is interesting and informative to anyone interested with the progress of human civilization, and what laws it is development.
