(ii) Discuss the major components of population growth.  

(iii) Define age structure, death rate and birth rate.  

(iv) How is migration a determinant factor of population change?  

Answer 2:  

(i) The family planning programme helped in increasing the awareness about the benefits of smaller family size. This helped in reducing the rate of population  growth in India since 1981.  

(ii) Birth rate, death rate and migration are the major components of population  growth. A higher birth rate; coupled with a lower death rate leads to population  growth. International migration can lead to population growth of more number of  people are coming from other countries than the number of people going outside  the country.  

(iii) Age Structure: Relative percentage of various age groups in the population  is called age structure of the population. Age group is generally divided into  children (upto 14 years), working age (15 – 59 years) and aged (60 years and  above).  

Death Rate: The number of deaths per 1000 persons is called death rate. 

Birth Rate: The number of live births per 1000 persons is called birth rate.  

(iv) Migration within the country is called internal migration, while that between  two countries is called international migration. Internal migration has no change  on population size but it changes the population composition of a particular area.  International migration can lead to a growth or degrowth in population;  depending on the degree of immigration and emigration. 

 

Question 3: 

Distinguish between population growth and population change. Answer 3: 

Population growth is about increase or decrease in the population.

Population  change is about changes in population composition; like age

structure, sex ratio,  literacy rate, occupational structure, etc.  

Question 4: 

What is the relation between occupational structure and development? 

Answer 4: 

Occupational structure greatly affects the development of a country. A large  portion of the Indian population is still dependent on the primary sector for  employment; which is one of the reasons for lack of development in India.  Examples of developed nations suggest that when a greater portion of population  engages in secondary and tertiary activities, it leads to proper development.  

Question 5: 

What are the advantages of having a healthy population?  

Answer 5: 

A healthy population helps in building a productive workforce for

the country.  Even the non-productive age group needs to be healthy to

reduce the burden of  healthcare. Healthy children would grow into healthy

adults and would be able to  contribute better in the economy. Healthy

elders would mean less strain on the  resources.
