QUESTION.1:
(i) Why people are considered a resource?
(ii) What are the causes for the uneven distribution of
population in the world?
(iii) The world population has grown very rapidly. Why?
(iv) Discuss the role of any two factors influencing
population change.
(v) What is meant by population composition?
(vi) What are population pyramids? How do they help in
understanding about the population of a country?
Answer:
(i) People are considered a resource because with their demands
and capabilities they can create new resources. Nature’s bounty becomes
important only when people find it and make it useful for them. Hence, human
resource is also considered an important and potential resource for the
society.
(ii) The way in which people are distributed across the earth is
known as the pattern of population distribution. Actually more than 90% of the
world’s population lives in about 10% of the land surface. Some areas are
over-crowded and some are sparsely populated. Following are the various factors
responsible for this extremely uneven distribution of population in the world:
a. Geographical factors - Favourable topography, availability of mineral and fresh
water resources, favourable climate and soil fertility are some of the reasons
affecting population distribution e.g., Indo Gangetic Plains, Diamond Mines of
South Africa etc are densely populated.
b. Social and Cultural
factors - Areas of better housing,
education and health facilities are more populated. Places of religious and
cultural significance also attract people e.g., Varanasi, Jerusalem etc.
c. Economic factors - Places having more industries, transportation and
communication facilities provide better employment opportunities. People are
attracted to these places because of the above reasons e.g., Mumbai, Osaka etc.
(iii) The world population has grown very rapidly particularly
after 1800s. The reasons are growth in food supplies, improvement in medical
facilities, reduced death rate while the birth rate remained the same.
(iv) Birth rate, Death rate and Migration.
(v) Population composition refers to the structure of the
population. Population composition helps to know the number of males or female,
their age-groups, literacy, their occupation, their income level and health
conditions etc.
(vi) The tapering figure of the population based on age and sex
is termed as population pyramid. An interesting way of studying the population
composition of a country is by studying at the population pyramid.
