What Causes Population Growth?
Causes of population growth include high birth rate, low infant mortality, increased food production and improvement of public health. In the past, the death rate was high due to lack of food and poor health facilities. Discoveries and inventions in food and health sectors have saved lives.
High birth rate in an area contributes to high population growth. This is referred to as natural increase. In addition, good maternity services have helped to decrease mortality rate of kids younger than six. High production of food helps to reduce death that results from hunger and malnutrition. Improvement of health care facilities has been helpful in the control, diagnosis and treatment of different diseases.
