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.

Planned housing is necessary for more population on limited land. Exam tip: connect high density with housing policy.
View question detailsSafety services may be needed even in low-density risk areas. Exam tip: check risk factors with density.
View question detailsPopulation density is found by dividing the total population by the total area. The answer must be expressed as persons per square kilometre when the area is given in square kilometres. Here, forty lakh means 4,000,000 people, and the area is 10,000 square kilometres. Therefore, density is calculated as \\(4,000,000 \div 10,000 = 400\\) persons per square kilometre. This means that, on average, 400 people live in each square kilometre.
Option A is correct. A quick way is to cancel four zeroes from both numbers: 40 lakh divided by 10,000 gives 400. Option B is half the correct value, while C and D are larger values caused by incorrect division. The important point is to use population as the numerator and area as the denominator, and to retain the correct unit.
Services like education, health and transport attract people. Exam tip: treat services as a density factor.
View question detailsJobs attract people, but without housing planning, unplanned density can grow. Exam tip: write jobs plus planning.
View question detailsIf the same population is divided over less area, people per unit area increase. Exam tip: remember the inverse relation.
View question detailsIf population and area increase in the same ratio, the ratio remains nearly unchanged. Exam tip: use ratio thinking.
View question detailsIn density questions, interpretation is necessary along with calculation. Exam tip: write both formula and planning.
View question detailsPopulation density is a useful planning indicator along with calculation. Exam tip: remember formula, unit and interpretation together.
View question detailsWhen usable settlement area decreases, the same population gets concentrated in a smaller usable area. Exam tip: connect actual usable area with density analysis.
View question detailsDensity is a useful indicator but alone does not show full living conditions. Exam tip: connect density with services and management.
View question detailsWith equal population spread over larger area density becomes lower. Exam tip: understand inverse relation between area and density.
View question detailsNational average can hide local inequalities. Exam tip: analyse smaller scale along with average.
View question detailsWhen population and density are known area is found by dividing population by density. Exam tip: learn to rearrange the formula.
View question detailsLow density does not end service need but can create access challenges. Exam tip: also write planning needs of sparse areas.
View question detailsWith fixed area increasing population raises people per area. Exam tip: connect migration with density change.
View question detailsHigh density can pressure limited resource capacity. Exam tip: connect carrying capacity with resource limit.
View question detailsDensity can show not only pressure but also market and labour availability. Exam tip: give a balanced answer.
View question details(24000 \div 600 = 40) so area is 40 square kilometres. Exam tip: divide population by density to find area.
View question detailsMap interpretation needs both legend and spatial pattern. Exam tip: do not rush by seeing colours only.
