Population growth and population explosion

For millennia, the demographic situation has been characterized by a very slow increase in the number of people on Earth. Approximately ten thousand years ago on the planet the population was about five million people. By the beginning of a new era, the number of humanity reached two hundred to three hundred million. This growth is mainly due to the beginning of food production. In the period of medieval wars and epidemics, the rate of increase in numbers has slightly decreased. The sharp increase coincides with the beginning of the industrial revolution. About two hundred years ago there was a significant progress in the development of medicine, economics, science and other spheres of public life, which allowed to significantly expand the capacity of the human environment.

Since the 17th century, there has been a marked increase in the rate of population growth . In the 1820s-1930s, the number of people on the planet reached the first billion. After this, a sharp increase in population growth begins. There was a "demographic explosion".

In the twentieth century, especially in the second half, an unprecedented increase in population is observed. Along with this, the demographic situation was characterized by serious changes in mortality and fertility, the family and age structure of the world population. Migration and urbanization were noted, there were significant differences in the development of mankind, depending on the region of residence.

The demographic explosion in the 20th century is characterized by high absolute rates of population growth. Annually by the end of the century the number increased by ninety million people. UN experts believe that such rates will continue until 2015.

It should be noted that the sixth billion of the world 's population reached in 1997-98. According to experts, every eleven years until the middle of the 21st century will be added to a billion people.

It should be noted that the "demographic explosion" in developing countries is more pronounced. This is due to the appearance of new opportunities for these states. Having achieved independence, developing countries can more widely use the world's achievements in the field of medicine. With the participation and assistance of the world community, these states were able to eliminate various epidemic diseases that claimed thousands of lives. Thus, over several decades mortality rates have declined significantly. At the same time, the birth rate in developing countries remained high. This provoked a "demographic explosion."

A sharp increase in population growth is possible if fertility is reduced, given the fact that mortality in developing countries continues to decline steadily.

A modern "demographic explosion" is a large-scale phenomenon. Today, a sharp jump in the population increase is observed in a large number of states, covering a significant part of the entire population of the planet. In addition, there is a direct or indirect impact on the entire community in the world, since the demographic problem is becoming one of the most global today.

Experts note that the increase in the number of the European population was mainly associated with changes in the social, economic sphere of life. In other words, the development of these industries has provoked an increase in the number of people. In developing countries, the situation is the opposite. In these states, the growth of the population preceded economic and social development. As a result, in the developing countries, the already difficult situation of the population, connected with the problems of employment, ecology, and food supply, is exacerbated.
