Population Density

Correct answer: A. Pressure of people in an area

Density shows how concentrated people are in an area. Exam tip: link density with population pressure.

Correct answer: C. 382 persons per square kilometre

In 2011 India's average population density was 382 persons per square kilometre. Exam tip: remember 2011 and 382 together.

Correct answer: A. Population and area

Total population and total area are needed to calculate density. Exam tip: see both figures together.

Correct answer: A. वह क्षेत्र जहाँ प्रति इकाई क्षेत्रफल अधिक लोग रहते हों

A densely populated area has a large number of people living per unit area; therefore, option A is correct. Option B describes a sparsely populated area, while rural settlements or a declining population do not by themselves determine population density. Exam tip: remember population density as the number of people in relation to area.

Correct answer: A. Where fewer people live per area

The direct answer is A: a sparsely populated area is one where few people live per unit of area. The word sparse means thinly spread or not crowded. Step by step, consider the size of the land; count the people living there; if the population is small compared with the area, the population density is low and the area is sparsely populated. Option A is correct because it states low population per area. Option B is the opposite: many people indicate dense or thick population. Option C is not a definition, because markets may exist in both dense and sparse places. Option D is also not a definition; a place with only metropolises would generally be highly urban and potentially dense. Sparse does not mean completely empty; it means people are few and widely spread. Exam cue: sparse = few people per unit area.

Correct answer: A. High

Plains are favourable for farming settlement and transport. Exam tip: link fertile plains with high density.

Correct answer: A. Limited water availability and unfavourable living conditions

Desert regions receive very little rainfall, so water is scarce. Extreme temperatures, sparse vegetation, and difficulty in farming also restrict permanent settlement, resulting in low population density. Option B is the opposite of the correct idea because deserts generally have low rainfall. Exam tip: link climate and water availability with population density.

Correct answer: A. Steep slopes and difficult transport

The direct answer is A: steep slopes and difficult transport are reasons for low density in hilly areas. Relief, or the shape and height of land, affects where people can live and work. Step by step, steep slopes make house construction and roads difficult; transport becomes costly and slow; farming land is often limited and machines are harder to use; jobs and services may therefore be fewer; many people may choose flatter, more accessible places. Option A is correct because it gives two connected physical difficulties. Option B is wrong because very level land generally makes construction and transport easier. Option C is wrong because ports are found near suitable coasts or waterways, not everywhere in hills. Option D is wrong because farming is not always easy on steep land. Memory cue: difficult relief often means difficult roads, farming and settlement.

Correct answer: A. City with jobs and facilities

The direct answer is A: a city with jobs and facilities. Population density means the number of people living in a unit of area, often expressed as people per square kilometre. Cities commonly offer employment, markets, schools, hospitals, transport, housing and other services, so they attract migrants and support concentrated settlement. Option A is correct because these attractions make high density more likely, although every city does not have exactly the same density. Option B is wrong because a waterless desert has severe limits on drinking water, farming and daily life, so settlement is usually sparse. Option C is wrong because permanent snow areas have extreme cold, difficult transport and very limited economic activity. Option D is wrong because inaccessible mountains often have steep slopes, poor connectivity and fewer services, which generally discourage dense settlement. The question asks which area is most likely, not which area must always be dense. Exam cue: jobs plus services plus accessibility usually point to high population density.

Correct answer: A. Housing water and transport

High density increases demand for basic services. Exam tip: connect high density with service demand.

Correct answer: A. Comparing concentration of people in different areas

Density makes concentration of population in different areas comparable. Exam tip: remember density as a comparison tool.

Correct answer: A. Higher

The same population gives higher density in a smaller area. Exam tip: density rises when area decreases.

Correct answer: A. Higher

In the same area more population increases density. Exam tip: density rises when population increases.

Correct answer: A. Employment opportunities

Employment attracts people to settle in an area. Exam tip: consider jobs as a reason for high density.

Correct answer: A. Harsh climate

Harsh climate can make living and working difficult. Exam tip: remember climate as a density factor.

Correct answer: A. Bihar

According to 2011 Bihar had the highest population density among states. Exam tip: remember Bihar for highest density state.

Correct answer: A. Arunachal Pradesh

According to 2011 Arunachal Pradesh had the lowest density among states. Exam tip: remember Arunachal Pradesh for lowest density state.

Correct answer: A. Population density

More people per square kilometre increase density. Exam tip: treat per square kilometre as a unit clue.

Correct answer: A. To plan schools, hospitals, water supply and other services

Population density shows how many people live per unit area. Densely populated areas generally need more schools, hospitals, housing, water supply, transport and other public facilities, so administrators can distribute resources and plan services appropriately. The age of rocks, rainfall amount and the exact timing of earthquakes cannot be determined from population density. Exam tip: link population density with planning public services and allocating resources.

Correct answer: A. More

Population density means the number of people living in a unit of area, such as one square kilometre. When density is high, many people occupy a comparatively small space. This often produces greater crowding and stronger pressure on houses, roads, water, transport, schools, hospitals, and other services. High density does not describe every personal experience of crowding, but it is a clear general indicator of possible crowding.

Option A, “More,” follows directly from the meaning of high density. Options B and C contradict that meaning because they suggest little or no crowding. Option D is also unsuitable because crowding is not always exactly the same; it can vary between neighbourhoods and according to the amount of space and services available. Thus, high density generally means more crowding or pressure.

Correct answer: A. Far apart

In low density people are spread over a large area. Exam tip: link low density with scattered settlement.

Correct answer: A. Development of markets and services may become easier

More people increase demand for markets and services. Exam tip: remember both benefits and pressure of high density.

Correct answer: A. Pressure on resources

High density can increase pressure on water land and services. Exam tip: link density with resource pressure.

Correct answer: A. Distance may be high because people live far apart

In sparse settlement providing schools hospitals and roads can be difficult. Exam tip: link sparse density with access problems.

Correct answer: A. More people in less area

Population density compares the number of people with the amount of land they occupy. A small area containing many people has a high density because people are concentrated in that space. This idea is different from total population: a large region may have many people but still have low density if its area is very large. Therefore, both population and area must be considered when identifying density.

Option A is correct because “more people in less area” describes concentration, the simplest sign of high density. Option B describes the opposite pattern: few people spread over a large area, which usually indicates low density. Options C and D do not describe a population comparison at all. A forest may be dense in vegetation, but that does not by itself indicate high human population density.
