Geography
Population Density
जनसंख्या घनत्व
In this Class 9 Geography topic from the chapter Population, students learn how population density measures the number of people living in a unit area, usually per square kilometre. They explore the population-density formula, interpret maps and data, and compare densely and sparsely populated regions. The topic also explains how relief, climate, soil, water availability, transport, industries and employment influence settlement patterns and the distribution of population in India and around the world.
