i). This happens because nowadays people are aware of family planning. A maximum number of steps have been taken by the government in the promotion of a family planning program.

• Due to the increase in literacy rate, the citizens are more aware of the government schemes and policies and plan their families accordingly.

• Growth in small or nuclear families can be seen nowadays.

• Women’s education, as well as sex education, will also help in family planning.

• Availability of contraceptives.

ii). The major components that we come across in population growth are Birth rate, Death rate, and also migration.

• Defining the birth rate- It can be defined as the number of live births per thousand people in a year.

• As the birth rates are higher in India as compared to the death rate so it is one of the most important factors.

• Defining the death rate-It can be defined as the number of live deaths per thousand people in a year.

• Defining migration- It can be defined as the people’s movement across regions and territories.

• Migration can be of two types such as internal or external migration

• Internal migration does not affect the country but the area they will migrate to is affected as a group of individuals migrate within the country.

• Migration plays an important role as it defines the composition of the population in a country.

iii). Age composition can be defined as the population which refers to the number of people in different age groups across the country.

• To understand the socio and economic structure according to population the different age groups people can be found in children, working-age and aged people.

• Population charts can be made according to the percentage of children, working people, and aged ones.

• Children grouped in age below fifteen, and are required food, economically unproductive, and also need all the medical care.

• Working people are grouped in the category of age fifteen to fifty-nine years, and are economically productive.

• Aged people are grouped in categories above fifty-nine which means they are economically productive but are retired.

• The natural increase in population is the difference between birth and death rate, use of birth control measures declining the population growth.

iv). Defining migration- It can be defined as the people’s movement across regions and territories.

• Migration can be local and global.

• It can be seen that change in the human population is due to fertility, mortality, and migration.

• Migration flow can be more often important because the unexpected changes in the size of the population can be typically seen in migration than in fertility and mortality.

• Hence we conclude that change in statistics of the population is due to the movement of a group of people in an area permanently which results in an increase in that area.

The difference between population growth and populations are:

Relationship between occupational structure and development.

• Development is being related to the occupational structure by population.

• A higher percentage of the population being engaged in occupations like agriculture, animal husbandry, forestry, and fishing which is a primary occupation leads to underdeveloped countries.

• An increase in development in the country increases the secondary occupation such as manufacturing.

• The tertiary occupation involves occupations like banking, commerce, transport, and administration, which can be seen in highly developed countries.

Population wellbeing is implied to the gathering of people having the best physical and mental wellbeing.

• If the population is healthy there will be less risk of heart attack caused due to an increase in cholesterol levels.

• A healthy population decreases the weight of medical care which is being affected by unhealthy populations.

• The people with good health help in the result of making a sound country.

• It also helps in building up a productive workforce.

• Healthy people know their potential so that they may play an important role in the social, economic, and national development of the country.

The important agenda is to maintain reproductive health and other aspects.

• The Indian government launched the National population policy in the year 2000.

• Objective- Its main aim is to understand the need for contraception, personnel health, integrated services for child healthcare, and basic reproductive health.

• The second main aim of this policy is to bring the fertility rate to replacement levels.
