# The World Population – Distribution, Density and Growth

### The World Population Distribution, Density and growth

• How much world population was recorded at the beginning of the 21st century?
Ans: Over 6 billion population.
• Who stated that “Asia has many places where people are few and few place where people are very many”?
Ans: George B. Cressey.
• How many percentage of the world population lives in about 10 % of its land area?
Ans: 90%.
• How many percentage of the world populations are living in the 10 most populous countries?
Ans: 60%.
• What is population density?
Ans: The number of total population on a particular unit of land is called population density. For example – 382/square kilometer is the density of population in India (Census – 2011).
• What is population growth?
Ans: Change of population in s particular area between two points of time is known as growth of population.
• What is natural growth of population?

#### Ans: This is the population increased by difference between births and deaths in a particular region between two points of time.

• What is natural growth of population?
Ans: Natural growth of population means the population increased by difference between births and deaths in a particular region between two points of time.
• Natural growth=Births – Deaths. But, actual growth of population is calculated as follows:
• Births – Deaths + In migration – Out migration.
• What is positive growth of population?
Ans: When the birth rate is more than the death rate between two points of time or when the population increased due to permanent migration to a region is called positive growth of population.
• What is negative growth of population?
Ans: When the birth rate is less than the death rate between two points of time or when the population decreased due to permanent migration from a region is called negative growth of population.
• Which Continent has the highest growth rate of population.
Ans. Africa.
• #### Name a mineral belt in Africa Which has Dene’s population?

Ans. Katanga-Zambia Copper belt.

• Name three components of population change.
Ans.Birth rate’ Death rate and Migration.
• Who are emigrants?
Ans.Who moved out of place.
• Which country in the world has the highest growth rate of population?
Ans.Liberia.
• Why is population growth high in second stage of Demographic Transition?
Ans. High birth rate & low  death rate.
• What is the trend of population growth in third stage of Demographic Transition?
Ans. Stabl, Zeroor even negative.
• Why life expectancy reduces in some developing countries of Africa?
Ans. Due to deadly disease like HIV/AIDS.
• Demographic Transition?
Ans. This theory explains 3 staged model of demographic transition:
Stage (i) High birth rate, high death rate, low growth: Example Bangladesh.
Stage(ii) Initially high Barth rate, low death rate, high growth rate-example India.
Stage(iii) Low birth rate,low death rate, stable or low growth rate -example Japan.
• #### Classify the world into various region on the basis of population density

Ans.1 Areas of high Density:
(I) Monsoon Asia,South and South East Asia.
(Ii)Europe – river valley’s,coastal plains
(iii)Eastern coastal region of North America.
2: Areas of Medium Density
(i)Asia
(ii)Europe
(iii)U.S.A, Australia.
(iv)Africa, South America.
