Ans: Occupational structure has got a great impact on the development of any country. In India more than 60% of the population is engaged in the agricultural activities and thus, are still dependent on the primary sector for employment, which is one of the reasons for lack of development in India. The developed nations suggest that when a greater portion of population engages in secondary and tertiary activities, it leads to great development.

Q7. What are the advantages of having a healthy population?
Ans: It is rightly said, a healthy mind resides in a healthy body. Human resource is the most important resource for the development of a country. A healthy population helps in building a productive workforce for the country. If the health of the population is properly looked after, people can put in more number of working hours and thus, the production level of the country can be increased. 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 drain on the resources.

Q8. What is migration? How migration leads to population change?
Ans: Movement of people from one place to another; in search of livelihood is called migration. Migration can be classified into two:
(a) Migration within the country is called internal migration.
(b) Migration 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 decline in population; depending on the degree of immigration and emigration.
In India, Poverty and lack of employment opportunities in rural areas work as 'push' factors which result in migration to urban areas. Better employment opportunities in urban areas work as 'pull' factors for migration. Due to increased migration towards urban areas, the share of urban population has increased from 17.29% in 1951 to 27.78% in 2001.
