Answer 1

Answer:

Three differences between Population Growth and Population Change:

Population Growth:

(a) Population growth is the difference between birth rate and death rate plus migration per year.

(b) It is expressed in percentage.

(c) Growth rate was 2.14% per year as per census 1991. It has declined to 1.93% per year in 2001.

(d) Growth of population refers to the change in the number of inhabitants of a country/territory during a specific period of time, say during the last ten years.

Population Change:

(a) Population change is the number of people added to the total population in a year.

(b) It is expressed in the addition of number of people.

(c) Population was 84.64 crore in 1991. It increased to 102.87 crore in 2001, an addition of 18.2 crore in a decade. 

(d) Population change is about changes in population composition; like age structure, sex ratio, literacy rate, occupational structure, etc.

Development is related to occupational structure of the population. Countries are less developed where a higher percentage of population is engaged in primary occupations like agriculture, animal husbandry, forestry and fishing.

As development takes place more people move into secondary occupations like manufacturing. In highly developed societies, there are a high percentage of people involved in tertiary occupations like banking, commerce, transport and administration.

The advantages of having a healthy population are:

A healthy individual is much more efficient and productive than an unhealthy individual.

He or she is able to realize his or her potential, and play an important role in social and national development.

Absenteeism is low where the workers are healthy.

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
