Population Growth

जनसंख्या वृद्धि

In Class 9 Geography, within the chapter Population, students study population growth as the change in the number of people over time. The topic explains how birth rates, death rates, and migration influence population size, and helps learners understand why growth patterns vary across places and periods.
