Geography
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
If births are 1200 deaths are 800 in migration is 500 and out migration is 300 what is the actual change?In which situation can total population appear stable but age structure may change?Why should source area and destination area be studied separately in migration analysis?In which condition can rural to urban migration increase pressure of unplanned settlements in cities?If birth rate is falling but total births are high what is the most likely reason?In which situation will the effect of a birth rate reducing policy not appear immediately?In which condition will natural change be low but actual change be high?If births are 700 deaths are 900 in migration is 500 and out migration is 100 what will be total change?In which condition will urban population growth be called mainly migration based rather than natural?In which condition can dependent population share rise in a source area?In which condition can migration create a dual effect on an area's economy?In which condition will both push and pull factors work together?In which condition can falling death rate make natural increase rapid?In which situation will planning for elderly population be needed along with falling death rate?In which condition can studying population change only by total number give a wrong conclusion?If in migration is high but skill training is weak what challenge will arise?In which condition can international migration change a country's service planning?If both births and deaths are high but their difference is small what will natural increase be like?In which condition will comparison of natural increase be misleading?Why can boundary change affect comparison of population change?
