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
In which situation will population density information be most useful for disaster management?HardLevel 75If a city has very high density why does public transport become more important?HardLevel 75When density increases in an area what change may be needed in water supply planning?HardLevel 75If an area has very low density but is developing through tourism how can local density change?HardLevel 75In which condition can food supply pressure rise when density is high?HardLevel 75If an area has high density but few open public spaces what effect is possible?HardLevel 75A state has low average density but mining towns are dense which conclusion is correct?HardLevel 75If an area has high population density and few schools what should be the main basis of education planning?HardLevel 75If an area's population density is much higher than national average which question is most important?HardLevel 75If an area has low density but is very large what administrative challenge may occur?HardLevel 75Why can land value rise when density increases in a city?HardLevel 75If two cities have the same density but one has better transport why can living pressure differ?HardLevel 75Which option gives the correct analytical difference between density and distribution?HardLevel 75Why is density important while planning disease control in a dense area?HardLevel 75If an area has low density but health centre is very far what will be the main problem?HardLevel 75If high density and low housing availability exist together in an area what result is possible?HardLevel 75If industrial employment grows in an area but housing and water planning do not grow what will be the effect of density?HardLevel 75Which information should be seen together for correct interpretation of population density in an area?HardLevel 75What is the most mature conclusion in the topic of population density?HardLevel 75If population is not decreasing in a dense area but water supply is improved what is the correct conclusion about density and resource pressure?HardLevel 74
