Answer: The distribution of population in the world is uneven. Some areas are very crowded while some are sparsely populated. There are various reasons behind this uneven distribution:
(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. Whereas desert regions like Sahara, mountainous regions like Himalayas and cold regions like Antarctica etc are sparsely populated.
(b) Social and Cultural factors: Areas of better housing, education and health facilities are more populated. eg. Pune. Places of religious and cultural significance also attract people e.g., Varanasi, Jerusalem etc.

Answer: The world population has not been stable and has increased manifold due to advancements in science and technology. Science and Technology has increased the food production and development in healthcare facilities has helped in reducing death rate.
(iv) Discuss the role of any two factors influencing population change.
Answer: Two factors influencing the change in population are birth rate and death rate. Birth rate is the number of births per 1,000 people and death rate is the number of deaths per 1,000 people. Births and deaths are the natural causes of population change. When the birth rate is more than the death rate, it means that the population is increasing and vice-versa. The difference between the birth rate and the death rate of a country is called the natural growth rate.

Answer: The graphical representation used to study the composition of a country’s population is called the population pyramid. It is also named as the age−sex pyramid.
