Natural Growth of Population Explained
Natural population growth measures the change in population size due purely to births and deaths.
It is calculated as the difference between the number of births and the number of deaths over a specific period.
The formula can be represented as:
$ \text{Natural Growth} = \text{Number of Births} - \text{Number of Deaths} $
This metric focuses solely on the balance of natural increase (births) versus natural decrease (deaths).
Distinguishing Natural Growth from Migration
Options related to immigration and emigration describe population change due to movement of people (migration), not natural processes.
- Excess of immigration over emigration refers to net migration, which affects the total population but not the natural growth rate.
- Excess of in-migration over out-migration is another way to describe net migration.
Therefore, the natural growth of a population specifically refers to the excess of births over deaths.
Important Questions from Population Geography - Teaching
- Arrange the demographic cycle in sequential order:
A. Early Expanding (Decline of death rate while birth rate remains high)
B. Declining (Low death rates and birth rates fall below death rates)
C. High stationary (High birth and High death rate)
D. Low Stationary (Low birth and low death rate)
E. Late expanding (death rate declines and birth rate begins to fall)
Choose the correct answer from the options given below: - Consider the following statements and choose the correct option.
Statement (A): Investment in non-farm activities in rural areas can reduce the rural urban migration.
Statement (R) : Migration increases during particular season when there are no agricultural activities in rural areas. - A population pyramid with big base and skinny top shows :
(a) High birth rates
(b) High death rates in higher age group
(c) Relatively large number of young population
(d) Large number of deaths of infants - Who developed the theory of demographic transition ?
