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.
Practice questions
If an area has a population of twelve lakh and an area of two thousand square kilometres, what will be its population density?HardLevel 76If two areas have the same population but Area A has half the area of Area B, which will have higher density?HardLevel 76If a state has high total population but low density, what can be the most likely reason?HardLevel 76If a district has medium average density but its city centre is very crowded, which conclusion is correct?HardLevel 76If an area's population increases while its area remains the same, what change will occur in density?HardLevel 76If an area's area doubles while population remains the same, what will happen to density?HardLevel 76If Area A has ten lakh population and five hundred square kilometres area, and Area B has twenty lakh population and two thousand square kilometres area, which has higher density?HardLevel 76If a district has high density but low water availability, what will be the most important planning issue?HardLevel 76If a state has high density but population growth is slowing, what is the correct analysis?HardLevel 76If an area has low density but people are settled only along the river, which study is necessary?HardLevel 76Why is population density considered very high in a state like Bihar?HardLevel 76What can be a balanced reason for low density in an area like Arunachal Pradesh?HardLevel 76If an area has low total population but very small area, why can density be high?HardLevel 76If a city has very high density and very few green spaces, what effect is possible?HardLevel 76Why is population density considered highly useful in development planning?HardLevel 76If an area has high density and weak sanitation, which problem can increase the most?HardLevel 76If an area has medium density but very few job opportunities, what situation can arise?HardLevel 76If digital connectivity and remote work increase, what effect can occur on low-density areas?HardLevel 76If an area has many mineral resources but low water and housing facilities, what is a balanced estimate of density?HardLevel 76If an area has population of fifteen lakh and area of two thousand five hundred square kilometres, what will be its density?HardLevel 76
