and urbanization, which have led to a rise in job opportunities and

(iv) Discuss the role of any two factors influencing
population change. Answer: Two factors influencing population change are as
follows:
- Birth
rate: The birth rate refers to the number of births per thousand people in
a population. A high birth rate results in a population increase, while a
low birth rate results in a population decline. The birth rate is
influenced by various factors such as availability of resources, culture,
education, and government policies.
- Death
rate: The death rate refers to the number of deaths per thousand people in
a population. A high death rate results in a population decline, while a
low death rate results in a population increase. The death rate is
influenced by factors such as availability of healthcare, sanitation, and
nutrition.
(v) What is meant by population composition? Answer:
Population composition refers to the distribution of people in a population
according to their age, sex, education, occupation, income, and other
demographic characteristics. It helps in understanding the social and economic
structure of a society and the distribution of resources and opportunities.
(vi) What are population pyramids? How do they help in
understanding about the population of a country? Answer: Population pyramids
are graphical representations of the distribution of a population according to
age and sex. They are useful tools for understanding the demographic structure
of a population, as they can help identify trends in birth and death rates, and
changes in population growth rates. They can also provide insights into the
social and economic conditions of a country, such as the level of education and
occupation of the population. Population pyramids can help policymakers and
planners in making decisions about healthcare, education, employment, and other
social and economic issues.
