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: - Which of the following statements are true with respect to stationary and stable population?
A. A stationary population is not always stable.
B. A stationary population is always stable.
C. A stable population need not be stationary.
D. In stationary population, the rate of overall change in the population is zero
E. In stable population, the rate of overall change in population is constant (not necessary zero)
Choose the correct answer from the options given below: - Who developed the theory of demographic transition ?
Match List – I with List – II and select the correct answer from the codes given below :
List - I
(General Terms)
List - II
(Definitions)
I. Crude birth rate A. Births over deaths per thousand of population II. General fertility rate B. Number of deaths per thousand of population III. Natural increase of population C. Ratio between number of births and number of females in productive age IV. Death rate D. Ratio between the number of births and total population
Codes:- When 0 – 14 and 15 – 44 age groups population of a country is almost identical, the growth of population would be called
