Population Density

Population density means the number of people living per unit area. Since 400 persons per square kilometre is greater than 200 persons per square kilometre, the first area has a higher concentration of population. Option D is not necessarily correct because total population also depends on the area of the region. Exam tip: while comparing density, compare the values stated per square kilometre.

Density is an average value and can hide local differences. Exam tip: distinguish average and local pattern.

Average density may not clearly show town village difference. Exam tip: focus on internal variation.

An area with low population density can still be very important because of minerals, energy resources, border location, or defence value. Thus, low density does not imply low economic or strategic importance. Options B, C, and D describe situations associated with high population density. Exam tip: treat population density and an area's economic or strategic importance as separate ideas.

Effect of high density depends on service capacity. Exam tip: understand density in context of services.

High density with inadequate services creates pressure. Exam tip: link capacity with density.

Carrying capacity is linked with limits of resources. Exam tip: connect pressure with resources and density.

Population density means the number of people living per unit area. Therefore, a density above the national average means that the area has more people per unit area than the national average. It does not necessarily mean that its total population is larger, because even a small area can be very densely populated. Exam tip: In density questions, focus on population divided by area, not on total population alone.

Lower density indicates lower concentration. Exam tip: understand lower than average as low concentration.

When population density rises in a city, more people need places to live, work, travel, study, and receive services. This can increase demand for land for housing, roads, schools, hospitals, markets, parks, and other facilities. If the available land is limited, competition between different uses may become stronger, and buildings may become more closely packed or grow vertically. Planning is needed to provide services while protecting open spaces and managing congestion.

Option A is correct because higher urban density can raise the demand for land for housing and services. The word “can” allows for different outcomes depending on planning and city expansion. Option B is unreasonable because people still require land and facilities. Option C is the opposite of the likely effect, and option D is physically unrelated. Rising density changes the pressure and pattern of land use; it does not eliminate land.

Density makes areas of different sizes comparable. Exam tip: treat density as a comparison tool.

Small area and high population together give high density. Exam tip: remember small area plus population.

Roads can increase local settlement by improving access. Exam tip: link accessibility with density factor.

Industries attract population by providing jobs. Exam tip: write industry as an economic pull factor.

When more people depend on limited farmland land pressure rises. Exam tip: understand land pressure.

A small area can give high density even with low total population. Exam tip: separate total and density.

A large area can spread high population and keep density low. Exam tip: check the denominator that is area.

Density helps estimate demand for water land and services. Exam tip: link density with demand estimation.

High population density does not always produce severe resource pressure if a place has strong systems for managing resources and delivering services. Efficient water supply, sanitation, waste collection, public transport, housing policy, health care, and energy distribution can help many people use limited resources more effectively. Good planning can also reduce waste, improve infrastructure, and match services with population needs. Thus, density describes concentration, while pressure depends partly on capacity and management.

Option A is correct because strong resource management and service capacity can reduce the pressure felt by residents, even where many people live close together. This does not mean that every problem disappears or that high density has no challenges. Options B, C, and D would normally increase hardship rather than reduce it, because the absence of water, closed services, or unavailable housing makes resources and living conditions more difficult. The question asks when pressure may feel lower, not when it vanishes.

In low density distance and access problems can make life difficult. Exam tip: understand practical effect of sparse settlement.
