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 a region has low average density but border areas are strategic, what caution is needed in planning?HardLevel 76If housing is costly but the employment centre is dense, how can the spread of population density change?HardLevel 76If markets and services increase after a road is built in an area, what possible effect will occur on density?HardLevel 76If two areas have the same density but one has higher total population, what can be said about it?HardLevel 76If an area has high density but weak public transport, which pressure can increase?HardLevel 76If an area has low density but health centres are very far, what will be the planning challenge?HardLevel 76If an area's density is eight hundred persons per square kilometre, what does it mean?HardLevel 76If an area has low density but industries begin to develop, what is possible in future?HardLevel 76In which situation can planning pressure be lower despite high density?HardLevel 76If a district has population of thirty lakh and area of six thousand square kilometres, what will be its density?HardLevel 76If a town has high density and few employment opportunities, which result is possible?HardLevel 76If an area's average density is low but one mining town is very dense, what does it indicate?HardLevel 76If population density is very high, is reducing population the only solution?HardLevel 76If an area has low density but everyone is settled in a small valley, what limitation of the measure appears?HardLevel 76If an area has high flood risk but also high density, what should be understood?HardLevel 76If density is increasing in an area but the number of schools remains the same, what pressure will arise?HardLevel 76If an area has high density but water, housing and jobs are all adequate, how should the conclusion be?HardLevel 76If an area has low density but roads and internet improve, what change is possible?HardLevel 76If an area has population of eighteen lakh and area of three thousand square kilometres, what will be its density?HardLevel 76If a state has high population density but most population is concentrated in a few towns, what caution is needed at state level?HardLevel 76
