Question

Large gap between birth and death rates will result in
A) More old people
B) Low rate of fertility
C) More school going children
D) Low dependency ratio

Answer 1

Hint:In population ecology, naturality is the scientific term for the rate of birth. In addition to the rate of death, the birth rate is used to calculate population dynamics.

Complete answer:
More elderly people in the population would have a difference between birth and death. The ratio of the number of births to the size of the population where mortality is the state of death is the birth rate.
The large difference between birth and death indicates an increase in life expectancy. It ensures the longevity and survival of the elderly. This results in a rise in the population of the elderly. It also increases the size of the population.

Population change is governed by the equilibrium between the birth rate and the death rate.
If the birth rate remains the same and the death rate decreases, the population will increase.
If the birth rate increases and the death rate remains the same, the population will therefore increase.
The major causes of death are illness, famine, injuries and war. Contributing factors such as poverty, provision of health care , education and other social and economic factors underlie these direct causes.
Demographic transition is a process of radical change that transforms a country from high rates of birth and death to low rates of birth and death.During the transition, the death rate declined first, followed by a fall in the birth rate.

Step 1: High birth rate and death rate
Step 2: Continued high birth rate, decreasing death rate
Step 3: Declining birth rates and death rates, gradually stabilising
Step 4: Death rate and population growth slow down
Step 5: Negative growth of population

Thus the correct answer is option (A) More elderly people.

Note:Births, deaths and migration are the major direct factors responsible for demographic change. The rate of change varies in various regions of the world. Population figures are increasing, but the rate of growth is decreasing all over the world.
