⚠️ Top Mistakes to Avoid on This Topic
- Confusing emigration and immigration: Emigration = Exit (leaving). Immigration = In (arriving). Think: E = Exit, I = In.
- Not classifying push/pull factors: Always label each factor as economic, political, social, or environmental.
- Confusing population density with total population: Density = people per area. A country can have a large population but low density (e.g., Canada).
- Forgetting to address both positive AND negative effects: Questions about urbanisation and migration usually want both sides.
Question 1 Easy
Define population density and calculate for Japan.
1
Definition: Population density is the number of people living per unit of area, usually expressed as people per square kilometre (people/km²).
2
Formula: Population density = Total population ÷ Total area.
3
Calculate: 126,000,000 ÷ 378,000 km² = ~333 people/km².
Population density = people per km². Japan: 126M ÷ 378,000 = ~333 people/km².
Question 2 Easy
Difference between emigration and immigration.
1
Emigration: The act of leaving one’s home country to live in another country. The person is an emigrant from the perspective of the country they are leaving.
2
Immigration: The act of arriving in a new country to live there. The person is an immigrant from the perspective of the country they are entering.
3
Example: If a person moves from Mexico to the United States, they are an emigrant from Mexico and an immigrant to the United States. Same person, same move — two different terms depending on perspective.
Emigration = leaving a country (Exit). Immigration = entering a country (In). Example: a person leaving Mexico emigrates; arriving in the USA, they immigrate.
Question 3 Easy
List two push factors and two pull factors, classified.
1
Push factor 1: War or political persecution (political push factor) — people flee conflict zones to survive.
2
Push factor 2: Natural disaster or drought (environmental push factor) — crops fail, homes are destroyed.
3
Pull factor 1: Better job opportunities (economic pull factor) — higher wages and more jobs attract workers.
4
Pull factor 2: Family reunification (social pull factor) — people move to be near relatives who have already migrated.
Push: war (political), drought (environmental). Pull: jobs (economic), family (social).
Question 4 Medium
Three factors that attract large populations to a place.
1
Access to water: Freshwater rivers, lakes, and coastlines provide drinking water, irrigation for agriculture, and transportation routes. Most of the world’s largest cities are located near rivers or coasts (e.g., Cairo on the Nile, London on the Thames).
2
Fertile land for agriculture: Flat, fertile plains with good soil support farming, which feeds large populations. River floodplains and deltas are especially productive (e.g., Ganges Delta in Bangladesh, Nile Valley in Egypt).
3
Moderate climate: Areas with temperate climates (not too hot, not too cold, adequate rainfall) are more comfortable for human settlement and agriculture. Extreme climates (polar, desert) tend to have low population density.
Water access (rivers/coasts), fertile land (agriculture), moderate climate (comfortable living and farming).
Question 5 Medium
Voluntary vs. forced migration with examples.
1
Voluntary migration: The person chooses to move, usually for economic or social reasons. Historical example: Irish immigrants moving to the USA in the 1800s seeking better economic opportunities. Modern example: A software engineer moving from India to Silicon Valley for a higher-paying job.
2
Forced migration: The person is compelled to move due to war, persecution, natural disaster, or government policy. Historical example: The Atlantic slave trade (16th–19th centuries), in which millions of Africans were forcibly transported to the Americas. Modern example: Syrian refugees fleeing the Syrian Civil War (2011–present), with millions displaced to Turkey, Jordan, Lebanon, and Europe.
Voluntary = choice (Irish to USA for jobs). Forced = compelled (slave trade; Syrian refugees fleeing war).
Question 6 Medium
Urbanisation: definition, two positive and two negative effects.
1
Definition: Urbanisation is the process of population shifting from rural areas to cities, resulting in the growth of urban areas. It is driven by industrialisation, economic opportunities, and rural push factors.
2
Positive 1 — Economic growth: Cities offer more jobs, higher wages, and better access to markets, boosting economic development.
3
Positive 2 — Better services: Cities provide better access to healthcare, education, public transportation, and cultural opportunities.
4
Negative 1 — Overcrowding and housing shortages: Rapid urbanisation can lead to slums, homelessness, and inadequate housing (e.g., favelas in Rio de Janeiro, Brazil).
5
Negative 2 — Pollution and environmental damage: More vehicles, factories, and waste generation lead to air and water pollution, loss of green spaces, and strain on water supplies.
Urbanisation = rural-to-urban population shift. Positive: economic growth, better services. Negative: overcrowding/slums, pollution.
Question 7 Medium
High birth rate + falling death rate: what happens?
1
a) Population effect: The population grows rapidly. More people are being born than are dying, creating a “population explosion.”
2
b) Challenges: Strain on resources (food, water, housing), overcrowded schools and hospitals, youth unemployment, environmental degradation, and potential for poverty if the economy cannot keep up with population growth.
3
c) Demographic pattern: This is characteristic of Stage 2 of the Demographic Transition Model (DTM). In Stage 2, death rates fall (due to improved medicine, sanitation, and food supply) while birth rates remain high, leading to rapid population growth. Many countries in Sub-Saharan Africa are currently in this stage.
a) Rapid population growth. b) Strain on resources, overcrowding, youth unemployment. c) Stage 2 of the Demographic Transition Model.
Question 8 Hard
Compare population distribution of Japan and Canada.
1
a) Japan’s density: 126,000,000 ÷ 377,000 km² = ~334 people/km².
2
a) Canada’s density: 38,000,000 ÷ 9,980,000 km² = ~3.8 people/km².
3
b) Why Japan is so dense: Japan is mostly mountainous (~73%), so the population is concentrated on narrow coastal plains. The Kanto Plain (Tokyo area) alone holds ~35 million people. Japan’s temperate climate and fertile valleys support dense settlement. Limited habitable land + large population = very high density.
4
b) Why Canada is so sparse: Canada is the world’s second largest country by area, but most of its northern territory is subarctic/arctic tundra, boreal forest, and permafrost — too cold for agriculture and comfortable living. About 90% of Canada’s population lives within 160 km of the US border, in the temperate southern strip. Vast northern areas are essentially uninhabited.
Japan: ~334/km² (dense — limited flat land, mountains concentrate people on coasts). Canada: ~3.8/km² (sparse — vast cold northern territory, people cluster near US border).
Question 9 Hard
Refugee vs. economic migrant — why does the distinction matter?
1
Refugee: A person who has been forced to flee their country due to war, persecution, or violence and cannot safely return. Defined by the 1951 UN Refugee Convention. Refugees have legal protections under international law — countries are obligated not to send them back to danger (non-refoulement).
2
Economic migrant: A person who moves voluntarily to another country seeking better economic opportunities (higher wages, better jobs). They are not fleeing persecution. Economic migrants do not have the same legal protections as refugees — countries can choose whether to admit them.
3
Why the distinction matters: Under international law, refugees have the right to asylum and protection. Countries that signed the UN Convention must accept and protect refugees. Economic migrants are subject to each country’s immigration laws and can be denied entry or deported. Misclassifying refugees as economic migrants can put vulnerable people in danger.
4
Real-world example: The Syrian refugee crisis (2011–present) has displaced over 13 million Syrians. Millions fled to neighbouring Turkey (~3.6 million), Lebanon, Jordan, and Europe. As refugees, they are entitled to international protection and cannot legally be sent back to a war zone.
Refugee = forced to flee (war/persecution), legally protected (non-refoulement). Economic migrant = voluntary, subject to immigration law. Distinction matters because refugees have legal rights to asylum. Example: Syrian refugee crisis (13M+ displaced).
Question 10 Hard
Effects of migration on source and destination countries.
1
Source country — Positive: Remittances — migrants send money back home, boosting the economy. Example: Remittances to Mexico from the USA totalled ~$60 billion in 2023, supporting families and local businesses.
2
Source country — Negative: Brain drain — the most educated and skilled workers leave, depriving the home country of talent needed for development. Example: Many doctors and engineers emigrate from African countries to Europe or North America, creating shortages at home.
3
Destination country — Positive: Labour force boost — immigrants fill labour shortages, often in jobs that are hard to fill locally (agriculture, construction, healthcare). Example: The US agriculture industry relies heavily on migrant workers.
4
Destination country — Negative: Social tension — rapid immigration can create competition for jobs, housing, and public services, sometimes leading to anti-immigrant sentiment or cultural friction. Example: Debates over immigration policy in Europe following the 2015 migration crisis.
Source: positive (remittances), negative (brain drain). Destination: positive (labour force), negative (social tension over resources/jobs).
