What are the major components of population growth?

Answer:

Birth rate, death rate and migration are the three major components population growth.           

(i) Birth rate is the major component of growth because if birth rate is higher than death rate, growth rate will automatically increase.

(ii) Another major component is death rate. These days we find that there are improved health facilities and there is awareness among people about their health maintenance. With the result, death rate has declined leading to growth rate of the population.

(iii) Migration is another component of population growth. Though internal migration does not change the population of the country but it does affect the distribution of population within the country. International migration definitely changes the size of the population.
