Processes of Population Change

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.
