(i) Why are people considered a
(ii) What are the causes for the uneven distribution of
population in the world?
(iii) The world population has grown very rapidly.
(iv) Discuss the role of any two factors influencing
(v) What is meant by population composition?
(vi) What are population pyramids? How do they help in
understanding about the population of a country?
(i)People can make the best use of
nature to create more resources when they have the knowledge,
skill and technology to do so. This is why human beings are
considered a resource. It is the abilities of human beings which
help in transferring a physical material into a valuable
(ii)The distribution of population in
the world is uneven - some areas are very
crowded while some are sparsely populated. Geographical, social,
cultural and economic factors affect the distribution of
population. The flatness of land, moderate climatic conditions,
fertility of soil, availability of fresh water, presence of
mineral deposits are the geographical factors that affect the
The presence of good housing, educational and health
facilities; proximity to centres of religious or cultural
significance, and the presence of employment opportunities are
some of the socio-economic factors that influence how different
regions are populated.
(iii)The world population has grown
very rapidly because the death rate has gone down as a result of
the growth of food supplies and the improvement of medical
facilities. Also, unlike the death rate, the birth rate has
remained quite high.
(iv)The birth rate and the death rate
are two factors that influence population change. The birth rate
is the number of live births per 1000 people while the death rate
is the number of deaths per 1000 people. These are the natural
causes of population change. When the birth rate is higher than
the death rate, population increases. When the death rate is more
than the birth rate, population decreases. When the two rates are
equal, the population remains constant. Thus, the birth and death
rates affect the balance of population.
(v)Population composition refers to the
structure of the population of a particular region. The
composition of a population helps us to know the number of males
and females comprising the population, their age groups,
educational and technological skills, occupations, income levels,
health conditions, etc.
(vi)The population pyramid or the
age-sex pyramid is
a graphical illustration that is used for studying the population
composition of a country. It shows the present number of males
and females in a country along with their age groups. The
age-group distribution of population tells us the number of
dependents and the number of economically active individuals
present in the population.
