Distribution of Population

Correct answer: C. Transport strongly influences where people live because it changes travel time, accessibility, and the cost of reaching jobs and services. When high-speed rail connects nearby towns to a central city, residents can live outside the main city and still commute to employment, education, health care, and other facilities. Satellite towns may offer cheaper housing, more space, or a quieter environment. As a result, population can spread outward in a connected metropolitan pattern rather than remaining concentrated in the centre. A is wrong because improved transport can encourage some households to move away from the core city. B is wrong because connectivity usually makes nearby towns more attractive, not empty. D is wrong because transport accessibility is an important influence on residential choice. The likely result is decentralisation with continuing links to the central city. Memory cue: better transport often spreads population while preserving metropolitan connections.

Correct answer: B. Population distribution changes through more than one process. Mortality is part of natural change: when deaths rise, the number of people may decrease if other conditions remain similar. Outward migration is a spatial movement in which residents leave the region for another place. If both processes occur together, studying only mortality would ignore the movement of people, while studying only migration would ignore deaths within the region. Area size is useful for calculating density, but it does not by itself explain why people are present or absent. Therefore, a complete interpretation must examine the combined effects of natural demographic change and migration, along with the conditions that produced them. A and C are incomplete because each considers only one process. D is wrong because area alone cannot explain population distribution. B is correct. Memory cue: population change has two broad pathways—natural change and migration; examine both when both are mentioned.

Direct answer: D is correct. Population distribution means how people and settlements are spread across space. First, a bridge reduces travel time and improves accessibility between the delta and the industrial zone. Second, workers can commute more easily, while industries can receive labour, goods, and services. Third, demand for houses, shops, schools, transport stops, and other facilities may rise near the bridge. As a result, settlement may grow in a linear pattern along the corridor or around important junctions. A is wrong because a bridge does not automatically depopulate a delta. B is wrong because its effects are not limited to river flow. C is wrong because better transport commonly influences commuting and settlement location. Memory cue: new transport routes often attract people, jobs, and services.

Direct answer: A is correct. Population distribution is connected not only with residence but also with access to employment, education, health care, administration, and other services. Here, many households live in suburbs, whereas important services are concentrated in the centre. People therefore travel regularly from suburban homes to the central area. This creates daily commuting and functional separation: the place of residence and the place where major activities occur are different. B is wrong because central services do not force every household to move into the centre. C is wrong because suburban housing remains important as the residential base. D is wrong because service location strongly affects travel and movement patterns. Memory cue: suburban homes plus central services usually means longer or more frequent commuting.

Direct answer: B is correct. Remittances are money sent by migrants to families in their place of origin. They may help households repair or build houses, pay for education, or improve consumption. However, receiving money does not necessarily mean that migrants have returned. If working-age people continue living and working elsewhere, the rural source region loses part of its active labour force. Its relative share of children, older people, or dependants may consequently rise, even while buildings and household incomes improve. A is wrong because remittances do not guarantee return migration. C is wrong because migration changes age and labour composition. D is wrong because housing is only one visible part of population distribution. Memory cue: money can return without the migrant returning.

Direct answer: C is correct. Environmental quality is an important factor in deciding where people are willing to live. When pollution controls make an old industrial district cleaner, health risks, unpleasant conditions, and negative perceptions may decline. If housing, transport, schools, health facilities, and employment are also adequate, former residents may return or new residents may be attracted. This can produce residential redistribution and urban regeneration. A is wrong because a district is not permanently empty merely because it was once polluted. B is wrong because population depends on several physical, economic, social, and institutional factors. D is wrong because effective pollution control can make settlement more attractive rather than less attractive. Memory cue: cleaner surroundings can reopen a place to residential use, but other facilities still matter.

Direct answer: D is correct. A freight corridor improves the movement of raw materials, finished goods, and commercial consignments. It may encourage logistics centres, warehouses, and industries at selected nodes. However, freight trains do not directly carry residents to work, schools, markets, or services. Without passenger services, many households cannot use the corridor for everyday travel, so broad residential redistribution may remain limited. A is wrong because logistics and industry can create employment. B is wrong because population is influenced by many factors, not passenger rail alone. C is wrong because freight movement does not always prevent housing, although noise or safety concerns may matter locally. Memory cue: freight supports production; passenger transport supports daily residential mobility.

Direct answer: A is correct. Population change has two broad components: natural change and migration. Natural increase depends mainly on births minus deaths. A low birth rate may reduce or slow natural increase, but it does not automatically make the total population fall immediately. If many people immigrate for jobs, education, health care, safety, or other opportunities, the inflow can offset the low number of births. The city may therefore retain a large and concentrated population. B is wrong because demographic effects are not instant. C is wrong because immigration directly adds residents. D is wrong because births and migration also matter. Memory cue: population change equals natural change plus migration.

Direct answer: B is correct. A favourable climate and efficient transport can attract residents by making a place comfortable and accessible. However, population attraction does not automatically create enough homes. Strict construction rules can restrict the supply of new dwellings, raise housing costs, and reduce the number of people who can settle legally or affordably. Thus, demand may be strong while actual settlement expansion remains limited. A is wrong because regulations can restrict, not expand, housing supply. C is wrong because land-use rules influence where and how many people can live. D is wrong because transport improves access but does not itself construct houses. Memory cue: attractiveness creates demand; housing capacity determines how much settlement can actually occur.

Direct answer: D. High-rise construction increases the number of people who can live in a small area, so residential density rises. However, population capacity is not determined by buildings alone. Water networks must supply enough water, and sewer systems must safely remove wastewater. If these systems remain unchanged, residents may experience shortages, interruptions, sanitation problems and declining living conditions. Over time, some households may prefer better-served neighbourhoods, while new residents may avoid the poorly serviced area. Option A is wrong because density can improve access to services only when capacity keeps pace. B is wrong because infrastructure is essential for healthy urban living. C is wrong because height alone does not measure carrying capacity. The memory cue is: more floors require more pipes, treatment and services.

Direct answer: A. Daily mobility depends on both where people live and where jobs are located. When many residents are concentrated in one or a few areas but employment is spread across several places, workers will have different destinations. Some may travel north, others south, east or west, depending on their workplaces. This produces multi-directional commuting flows rather than one single stream toward one centre. Option B is wrong because scattered jobs do not imply one common destination, and walking is not inevitable. C is wrong because the separation between homes and jobs creates a reason for commuting. D is wrong because residential density alone cannot explain movement; employment geography is equally important. Memory cue: concentrated homes plus scattered jobs equals many origin-destination links.

Good roads and reliable electricity create favorable conditions for economic activity, services, and accessibility, so they can attract population. However, prolonged political uncertainty can weaken investment, employment security, and people's confidence in long-term settlement. As a result, population concentration may remain lower than expected despite strong infrastructure. Therefore, the third option is correct. In examinations, population distribution should be analyzed through the combined influence of supportive and restrictive human factors such as infrastructure and political stability rather than through any single factor.

The correct answer is B: river valleys can support dense settlement. To understand this, population distribution means the way people are spread over the Earth. People usually prefer places where water, food, level land, transport and work are available. River valleys often provide dependable water, fertile alluvial soil, relatively flat land and routes for movement and trade. These advantages have supported agriculture, towns and civilizations over long periods. A is wrong because ice-covered land is generally unsuitable for regular farming and permanent dense settlement. C is wrong because steep, high mountains usually make construction, farming and transport difficult, although some valleys and accessible locations are exceptions. D is wrong because hot deserts generally have severe water shortages. Memory cue: water plus level, fertile land usually encourages settlement.

The correct answer is B: extensive level plains. Relief affects how easily people can build homes, cultivate land, move goods and expand settlements. On broad plains, construction and the development of roads, railways, irrigation systems and cities are generally easier and less expensive. Level land can also support larger fields and mechanised farming where other conditions are suitable. A is wrong because very steep slopes increase construction, transport and cultivation difficulties and may create erosion or landslide risks. C is wrong because an active glacial surface is unstable, extremely cold and unsuitable for ordinary permanent settlement. D is wrong because deeply dissected badlands have broken relief, poor connectivity and limited cultivable land. This is a general tendency, not an absolute rule: technology, resources and local conditions can create exceptions. Memory cue: flat land lowers the cost of building, farming and connecting places.

Industrialisation created jobs around production centres, expanded transport and market networks, and encouraged the growth of education, health care and other urban services. These attractions stimulated migration from rural or less prosperous areas, producing strong population concentration in certain industrial regions. Therefore option A is correct. Industrialisation did not eliminate farmland globally, nor did it cause universal migration to mountains. In exams, link industrial population concentration with employment opportunities, infrastructure development, migration and urbanisation working together.

Ports connect coastal cities with national and international markets. When ports expand, they often attract trade, factories, warehouses, transport companies, banks, offices, hotels, and other services. These activities create many kinds of jobs, so workers and their families move toward the metropolitan region. Better roads, railways, and communication may further strengthen this concentration. Thus, the direct link is between port-based economic activity and population growth.

Option A is correct because it includes the main economic forces that draw people to coastal cities. Seawater does not naturally become safe drinking water, so B is not a normal population factor. A ban on coastal agriculture would discourage settlement, not increase it. Coastal climates are not identical everywhere, making D incorrect. The answer is therefore A.

Transport routes strongly influence where people settle because they connect places with markets, jobs, schools, hospitals and supplies. When houses and activities appear in a narrow line along a road or railway, the pattern indicates that accessibility and movement are shaping settlement. This is a human and economic influence supported by infrastructure.

Roads and railways reduce travel time and transport costs. Stations, junctions and roadside locations attract shops, warehouses, industries, workers and services, so population grows along the route instead of spreading evenly in all directions. Rainfall, soil colour or latitude may influence settlement in other situations, but they do not best explain this clearly linear pattern. Therefore, option A is correct.

Dense population usually develops where several favourable conditions work together. A suitable climate makes daily life and farming easier, water supports drinking and irrigation, and fertile land produces food. Economic opportunities such as industry, trade, transport, education and services attract and retain people. Thus, population concentration is not explained by one physical factor alone; it commonly results from the combined influence of nature and human activity.

Option A is correct because it includes the main natural and economic advantages that encourage settlement. Extreme cold, permanent ice, severe aridity, inaccessible slopes and isolation generally discourage large settlements, so options B, C and D describe conditions more often linked with sparse population. The word “combination” is important: densely populated regions usually have both environmental suitability and opportunities for earning a livelihood.

Fertile land can support many people, but fertility alone does not guarantee a high local density. Population density also depends on jobs, services, transport, security, and the ability of people to remain in the area. If farming cannot provide enough income, residents may leave for education, factories, offices, or better services elsewhere.

Therefore, continuing large-scale out-migration can keep local density limited even while the total population grows or the land remains productive. Option A correctly identifies this balancing effect: people may be born or live in the region, but many working-age residents move away. The other choices make absolute claims that are not geographically valid.

Climate is important for settlement, but it is not the only influence on where people live. Employment, industry, transport, public services, history and security can make one place much more attractive than another, even when their natural conditions are similar.

Option A compares two regions with similar climates but different population densities and identifies different economic opportunities as the reason. This is strong comparative evidence because it holds climate broadly constant while showing another variable changing with population distribution. The other choices describe physical features but do not test whether climate alone is sufficient.

Being near the sea does not automatically make a region densely populated. Coastal settlement also depends on climate, terrain, accessibility, harbours, transport, jobs, and links with inland markets. A coast that is extremely cold, difficult to reach, and weakly connected may offer few reasons for people and businesses to settle there.

Therefore, option A is correct. The other choices describe conditions that usually encourage population concentration: ports and industries create jobs, favourable climate and broad plains support living and farming, and strong trade links improve movement and economic opportunity. Distance from the sea alone is not the deciding factor.

Population does not depend only on untouched natural conditions. People can use natural resources more effectively when dams regulate water, irrigation supports farming, and roads connect villages with markets and services. These facilities make a river valley more useful and attractive for settlement, so population may rise rapidly.

The valley already had water, level land, and other natural advantages. Infrastructure improves access to these advantages and creates opportunities in agriculture, energy, transport, trade, and services. Therefore, option A is correct. Option B is wrong because natural factors do not disappear; option C is wrong because water remains important; option D ignores the clear role of planned development.

Social factors arise from the way people organise their cultural, religious and social life. A place with religious or cultural importance may attract pilgrims, workers, traders, teachers and service providers. As these activities grow, people may settle permanently nearby, so the settlement becomes more concentrated.

Option A shows this direct social influence. The other choices describe physical factors: falling temperature with height is related to relief and climate, low rainfall is a climatic condition, and sediment deposition is a geomorphological process. Therefore A is the clearest example of a social or cultural factor shaping population distribution.

Government policy can influence where people live by changing the opportunities and facilities available in particular places. It cannot alter natural facts such as Earth’s latitudes, remove mountains instantly, or permanently eliminate oceans. However, it can invest in planned settlements, industries, roads, railways, irrigation, public services, and resettlement programmes. These measures make some previously less attractive areas more suitable for residence and employment.

Option A is correct because new industrial towns and transport corridors can create jobs, improve accessibility, attract investment, and encourage families and workers to settle there. Options B, C, and D describe physical changes that are not realistic direct actions of ordinary population policy. The example illustrates that government can reshape population distribution indirectly through planned economic and infrastructural development.

Natural resources attract economic activity, but they do not automatically create a large permanent settlement. A mineral-rich region may be remote, difficult to reach, very cold, dry, or otherwise harsh. High transport costs, limited water, weak infrastructure, and poor access to schools and health services can discourage families from settling there permanently.

Such a place may have temporary mining camps or workers who rotate in and out, while the long-term resident population remains small. Thus option A is correct because physical difficulty and isolation can outweigh the attraction of minerals. A metropolitan region, irrigated plain, or busy port normally offers better accessibility and services, so those choices do not best fit the question.
