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.

  3. Area doubles
  4. Population becomes half
Hard · Level 74 · population density,river valleys,himalayas,physical factors,settlement patterns,class 9 geography
View options
  1. Because both regions have similar relief and climate
  2. Because river valleys offer fertile land, water and transport facilities, whereas high altitude and rugged relief in the Himalayas make settlement difficult
  3. Because high Himalayas have more level land for agriculture
