Population Density

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

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

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

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

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

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

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

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

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.

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.

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

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

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

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

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.

In inaccessible and dry areas, scarcity of water, difficult transport, and limited farming opportunities discourage settlement. Therefore, such areas are likely to have low population density. In contrast, industrial cities attract people because of employment opportunities. Exam tip: areas lacking water, fertile land, transport, and jobs generally have low population density.

Irrigation and fertile land support farming and settlement. Exam tip: link irrigated area with high density.

When the same population spreads over a larger area density decreases. Exam tip: density falls when area rises.

More population in the same area increases density. Exam tip: link population increase with density increase.

Density does not tell income but tells concentration of people. Exam tip: do not mix density with income.
