Question
Give a geographical reason:
Population may increase though birth rates are low.
Solution
- The growth of the population depends upon the difference between the number of live births in a year per thousand population and the number of deaths in a year per thousand population. Therefore, the growth of the population depends upon both birth rate and death rate.
- When the birth rate is low and the death rate is also low, though the number of live births per thousand population is less, due to a smaller number of deaths per thousand population, there is an increase in the country's population.
