Defin the term
Underpopulation
The term overpopulation implies that there are not enough people to make full use of the resources and technology of the place they live in.
Give reasons
A large country may be underpopulated but highly developed.
A large country may be underpopulated but highly developed because of abundant natural resources, low fertility, technical development, high literacy rate and higher standard of living.
Give reasons
A small overpopulated country can be prosperous and developed or even undeveloped.
A small overpopulated country can be prosperous and developed or even undeveloped because the development of a country does not depend on its size but on its resources, health, death rate, literacy level, sanitation, technology, trade and political stability.
Differentiate between overpopulation and underpopulation.
Overpopulation:
* The term overpopulation implies that a region has too many people and not enough resources to maintain a reasonable standard of living.
* Eg: Bangladesh, Mali
Underpopulation:
* The term overpopulation implies that there are not enough people to make full use of the resources and technology of the place they live in.
* Equatorial Congo, Amazon River Basin,
rich Prarie regions of North America
Explain the correlation of birth and death rates with overpopulation
Due to improved technology, efficient healthcare and medical facilities, global birth rates have increased and death rates have decreased.
How does illiteracy impact overpopulation?
- Literacy and growth rates are directly related.
- Literacy rates in developing nations are low.
- An increase in literacy rates improves their general attitude towards birth control.
Lack of efficient and enforced family planning policies also leads to overpopulation.
How does emigration cause underpopulation?
- Emigration is the movement of individuals from one country to another to permanently settle in their destination.
- Push factors would be the negative factors associated with the current region or nation the individuals reside in, like lack of employment, oppressive political conditions, poor economies, etc.
- Pull factors are the favourable factors of the country that the individuals want to move to, like better employment opportunities, political freedom, economic stability, etc.
