What factors are responsible for Human Population growth?

Growth in the human population can be largely attributed to some advancement in the recent past in the field of agriculture, science, technology and health facilities. The surplus of food and other supplementary resources has provided ample space for the growing human population. Overpopulation at specific locations mainly cities can also result from migration in search of better living conditions.

Several factors which led to such unprecedented growth in the human population are:

1. Increase in Agricultural Productivity

Inclusion of modern techniques in agriculture like use of agrochemicals (like fertilizers, pesticides and insecticides) and modern machinery has led to multi-fold increase in agricultural yield. The surplus of food resources has been able to support the growing human population.

2. Decrease in Death Rate and Infant Mortality Rate

With the advancement in medical facilities including improved medicines and vaccines there has been a considerable worldwide decline in the death rate and infant mortality rate, which has led to larger population size.

3. Advancement in Science and Technology

Advance scientific technology which fueled the industrial revolution provided a surplus of resources that could support a larger human population.

4. Lack of Awareness

Illiteracy, poverty and lack of awareness about the harmful impacts of a large population have also led to the problem of overpopulation. Awareness and use of various family planning methods are also lacking in most highly populated countries.
