(iv)Discuss the role of any two factors influencing population change.

Answer:Two factors influencing population change are :-

  • Birth and death rates
    1. Births are usually measured using the birth rate i.e. the number of live births per 1,000 people.
    2. Deaths are usually measured using the death rate i.e. the number of deaths per 1,000 people.
  • Migration is another way by which population size changes. Within countries large number of people may move from the rural to urban areas in search of employment, education and health facilities.

Answer:Population composition refers to the structure of the population.

The composition of population helps us to know :

  • which age group they belong to,
  • how educated they are
  • what type of occupations they are employed in,
  • what their income levels and health conditions are.

Answer :A population pyramid shows :

  • The total population divided into various age groups, e.g., 5 to 9 years, 10 to 14 years.
  • The percentage of the total population, subdivided into males and females, in each of those groups.

A population pyramid in which the base is broad and the top part is narrow means that a large amount of births takes place but many died before reaching adult age. This indicates a large death rate.
