Processes of Population Change

जनसंख्या परिवर्तन की प्रक्रियाएँ

In this Class 9 Geography topic from the chapter Population, students learn how a population changes over time through the three basic processes of births, deaths and migration. They explore natural increase, birth and death rates, and how migration affects the size, distribution and composition of population. The topic also helps students connect these processes with factors such as health, living conditions, employment and social change, building a clearer understanding of population trends in India and beyond.

Practice questions

In which situation can total population change give a different result from natural increase?If birth rate is slightly higher than death rate but out-migration is very high, what may happen to total population?What is the most correct meaning of net migration in population change?In which situation will net migration be considered negative?On what basis is natural increase correctly understood?If births are low in a city but people are continuously coming for work, what will be the main cause of growth?In which situation will natural increase of population be positive?If infant mortality declines, what may be the initial effect on population change?Why can change in birth rate be slower than change in death rate?Which change can most directly reduce death rate?Where is the most complete form of total population change seen?If natural increase is zero but in-migration is high in a region, what will happen to total population?If births and deaths are equal but out-migration is high, what will be the effect on total population?What does the combined effect of push and pull factors do in rural to urban migration?Which example most clearly shows migration-based effect on population change?In which situation can total growth remain limited even when birth rate is high?How can out-migration of working-age people affect the age structure of the source region?Why can in-migration put pressure on services in the destination region?In which situation can population distribution of a state change while total national population does not change?If in-migration is high and out-migration is low in a district, what will net migration be?
