Question

Among the given options, which is the major component of population change?

• A. Migration
• B. Industrialisation
• C. Density of population
• D. Urbanisation

Hint:

Population change mainly occurs due to three factors: birth rate, death rate, and migration. Migration can rapidly change population distribution across regions.

Answer 1

The Correct Option is A

Population change refers to the variation in the size of a population over time. This change can occur due to three main factors: birth rate, death rate, and migration.

Birth rate and death rate determine the natural growth of population, while migration (movement of people from one place to another) significantly alters the population distribution and size in different regions.


• (A) Migration:
Correct. Migration is a major component of population change because it directly affects population size and distribution between regions.
• (B) Industrialisation:
Incorrect. Industrialisation may influence migration and population growth, but it is not a direct component of population change.
• (C) Density of population:
Incorrect. Population density is a measure of population per unit area, not a component causing population change.
• (D) Urbanisation:
Incorrect. Urbanisation refers to the growth of cities and towns but is not itself a direct component of population change. Among the given options, migration directly affects the size and distribution of population and is therefore a major component of population change. Final Answer:
Migration.
