Just answer the question, how many people currently living on the Earth, it is impossible, because every minute is born and dies a large number of earthlings.
Thus, the number of the world's population is constantly changing.
However, you can call the approximate number.
The population of the Earth today
Currently the world populationmore than seven billion people. According to statistics from the American CIA in July 2013. The number of people in the world was approximately 7,095,217,980 people. UN Secretary General Ban Ki-moon on the 47th session of the UN Population and Development Commission in early 2014, said in his report that the population was 7.2 billion people.
According to expert estimates, at present there is a slowdown in the world's population growth.
How is the count
To determine how many people live in the world,necessary to determine their number in individual regions and countries of the world. In many countries of the general population census conducted at regular intervals - every five, ten years, etc. But there are countries where the census carried out for a long time, or not at all were carried out. Therefore, to determine the total population of special calculations used in the world.
Not one millennium was the number of earthlingsrelatively low and increased slowly. Gradually, the population growth accelerated, and in the 20th century it became particularly stormy pace. On average, every day on the planet becomes 250 thousand more.
At the beginning of our era the world's population does not exceed300 million people. This figure has doubled in just the 17th century. Endless wars, epidemics significantly impeded the demographic growth of the population. The increase in production, the industry contributed to the increase of the population - in the early 19th century it was already a billion. By the 30th century, 20 years in this billion doubled, and after 30 years - has tripled. According to the October 12, 1999 at the world's 6 billion people lived. In the 20th century, in spite of the great loss of life in the First and Second World Wars, the population increased rapidly due to the reduction in mortality from disease and hunger, achievement of science and medicine.
According to UN projections, by 2025 the world population will exceed 8 billion by 2050 will amount to $ 9 billion.
In different regions of the Earth at different times of the value ofpopulation growth varies. It plays the role of the birth rate, mortality and life expectancy of people that, in turn, depends on various factors - the standard of living, crime, military conflicts, etc. In the so-called developed countries, the birth rate is low and long life expectancy. Conversely, in countries that are considered to be poorly developed, fertility rates are high, but high mortality and short life expectancy.
