Geographical factors include.

Water: People prefer living in areas where fresh water is easily available. The river valleys of the world are the densely populated regions, while deserts have spare population.
Social Factors include:
Social: Areas of better housing, education and health facilities are more densely populated. (For example: Pune)
Economic: Industrial areas provide employment opportunities. Large number of people are attracted to these areas. Osaka in Japan and Mumbai in India are two densely populated areas.
(iii) The world population has grown very rapidly. Why?

(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.
(v) What is meant by population composition?
Answer: Population composition refers to the structure of the population. The composition of the population helps us know how many are males or females, which age group they belong to, how educated they are, what type of occupations they are employed in and what their income levels and health conditions are. An interesting way of studying the population composition of a country is by looking at the population pyramid, also called an age-sex pyramid.
(vi) What are population pyramids? How do they help in understanding the population of a country?
Answer: The graphical representation used to study the composition of a country’s population is called the population pyramid. It shows the total population divided into various age groups, percentage of the total population subdivided into males and females and the number of dependents in a country. When the population of a country has high birth and death rates, the population pyramid is broad at the base and narrow towards the top.
