Population: In sociology, population means collection of human beings.

 

Demography: It is a branch of social science which deals with statistical study of human population.

 

Census: An official enumeration of population which is done periodically is called census. The first census in India was conducted in 1872, but the first complete census was conducted in 1881. After that, the census has been done every ten years.

 

Population Growth and Process of Population Change:

 

Birth Rate: The number of live births per 1000 persons is called the birth rate. According to 2011 census, the birth rate in India is 20.22 births per 1000 persons.

 

Death Rate: The number of deaths per 1000 persons is called the death rate. According to 2011 census, the death rate in India is 7.4 deaths per 1000 persons Migration: Migration is another factor which changes the size of population. Movement of people

from one place to another; in search of livelihood is called migration. 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.

 

Life Expectancy:The average age upto which the people are expected to live is called life expectancy. Literacy Rate:The literacy rate has increased from 65% in 2001 to 74% in 2011. But the literacy rate among females is still lower compared to that among males. This can be attributed to providing less opportunity to the girls.

 

Sex Ratio: The ratio of female to male population is called sex ratio. The sex ratio has shown a decline from 933 in 2001 to 914 female per 1000 male in 2011.

 

Age Composition: The composition of different age groups in the Indian population is often taken as one of the most positive indicators of population in India.

 

Children: People upto 14 years of Working Age: People between 15 to 59 years of age

 

Aged: People who are 60 years and above are considered as aged.

Question. What is the relation between occupational structure and development?
Answer : 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.
