Question

(iv) Discuss the role of any two factors influencing population change.

Answer 1

The rate of birth and death are the two most significant factors influencing population change. The birth rate is the number of live births per 1000 people. The death rate, on the other hand, is the number of deaths per 1000 people.

Answer 2

Explanation:

The birth rate and the death rate are two factors that influence population change. The birth rate is the number of live births per 1000 people while the death rate is the number of deaths per 1000 people. These are the natural causes of population change. When the birth rate is higher than the death rate, population increases. When the death rate is more than the birth rate, population decreases. When the two rates are equal, the population remains constant. Thus, the birth and death rates affect the balance of population.
