Population Geography Quiz: 20 Questions on People and Migration

Conceptual illustration of people with travel bags moving between a small village and a denser town along a path crossing a stream.


This population geography quiz tests how well you interpret population change and migration, not how many country rankings you remember. Work through 20 questions on density, fertility, age structure, migration and displacement, with explanations for every answer.

Population geography studies where people live and how populations change; migration geography examines movement and its connections between places. This combined practice set includes hypothetical calculations and scenarios. All information needed for the numerical questions is supplied, and legal definitions are identified where the distinction matters.

Medium

1. A hypothetical region has 100,000 people, 1,000 square miles of land (about 2,590 km²), and 200 square miles of arable land (about 518 km²). What are its arithmetic and physiological densities, respectively, per square mile?
Show answer

Correct answer: 100 people; 500 people.

Arithmetic density uses all land: 100,000 ÷ 1,000 = 100. Physiological density uses arable land: 100,000 ÷ 200 = 500. Both numerators count the entire population, not just farmers.

Easy

2. A hypothetical country records 6,000 live births in a year and has a midyear population of 400,000. What is its crude birth rate per 1,000 people?
Show answer

Correct answer: 15.

Divide 6,000 births by 400,000 people, then multiply by 1,000: the result is 15. The denominator is the total population, not only women of reproductive age.

Medium

3. In a hypothetical year, a region records 12,000 births, 9,000 deaths, 4,000 arrivals and 8,000 departures. With fixed boundaries, complete counts and no statistical adjustment, what happens to its population?
Show answer

Correct answer: It decreases by 1,000.

Natural change is +3,000, while net migration is −4,000. Adding them gives −1,000. Positive natural increase does not necessarily mean the total population grows.

Hard

4. Two populations have the same death rates within every age group. Why might the population with more older adults still have a higher crude death rate?
Show answer

Correct answer: Its age structure gives more weight to ages with higher mortality.

A crude death rate mixes age groups. Older ages generally have higher mortality, so a larger older share can raise the overall rate even when age-specific risks are identical. This is why age structure matters in comparisons.

Medium

5. A period total fertility rate of 1.8 births per woman is best understood as what?
Show answer

Correct answer: A hypothetical lifetime total if that period’s age-specific fertility rates continued.

Period TFR combines age-specific fertility rates into a synthetic lifetime measure. It is neither a count of this year’s births per woman nor the completed fertility of an actual birth cohort.

Hard

6. Why is replacement-level fertility not exactly the same number in every population?
Show answer

Correct answer: Survival to reproductive ages and the sex ratio at birth differ.

Replacement fertility depends on whether enough daughters survive to replace their mothers. Mortality and the sex ratio at birth therefore matter. A single replacement-fertility figure should not be treated as universal.

Medium

7. In two hypothetical population pyramids, children aged 0–4 are 10% of Region A’s 1 million people and 5% of Region B’s 3 million people. Which region has more children aged 0–4?
Show answer

Correct answer: Region B: 150,000 compared with Region A’s 100,000.

Convert each share into a count: 0.10 × 1,000,000 = 100,000 and 0.05 × 3,000,000 = 150,000. A wider percentage bar does not necessarily represent more people when total populations differ.

Hard

8. A hypothetical population has 30,000 people aged 0–14, 60,000 aged 15–64 and 10,000 aged 65+. Using these age bands, what is its total age dependency ratio per 100 people aged 15–64?
Show answer

Correct answer: About 66.7.

Add the two dependent-age groups and divide by the stated working-age group: (30,000 + 10,000) ÷ 60,000 × 100 ≈ 66.7. This is an age-composition measure, not a count of actual workers and financially dependent people.

Medium

9. In the classical demographic-transition model, what produces rapid natural increase during the early transition?
Show answer

Correct answer: Death rates fall while birth rates remain high.

The widening gap between births and deaths produces rapid natural increase. This is a simplified transition pattern, not a universal timetable. Real trajectories vary, and migration also affects actual population totals.

Hard

10. A youthful population reaches replacement-level fertility, mortality stays constant and net migration is zero. Why can it still grow for a time?
Show answer

Correct answer: Large cohorts entering reproductive ages can keep births above deaths.

This is positive population momentum: inherited age structure can sustain growth after fertility falls. Large reproductive-age cohorts can produce more births than the smaller older cohorts produce deaths. Replacement fertility does not fix the annual number of births.

Medium

11. Assume a hypothetical population continues to grow by 2% each year. Using the rule of 70, approximately how long would it take to double?
Show answer

Correct answer: 35 years.

The rule gives 70 ÷ 2 = 35 years. It assumes a constant percentage growth rate and is approximate; a changing growth rate would change the doubling time. It is not a forecast for a real country.

Medium

12. A hypothetical census reports 80,000 foreign-born residents on one reference date. A separate series records 5,000 immigrants during the preceding year. Which interpretation is correct?
Show answer

Correct answer: 80,000 is a stock; 5,000 is an annual flow.

A stock measures a defined population at a point in time. A flow measures movement during a period. The foreign-born stock may include people who arrived many years earlier, so it cannot be treated as this year’s inflow.

Easy

13. A hypothetical country receives 8,000 immigrants and records 8,000 emigrants in the same year. What can be concluded about its net migration?
Show answer

Correct answer: It is zero, despite substantial movement in both directions.

Net migration is arrivals minus departures: 8,000 − 8,000 = 0. Equal opposing flows do not mean nobody moved. Births and deaths can still change the country’s population.

Easy

14. Someone changes their usual residence from one Australian state to another. How is the move classified at the national scale?
Show answer

Correct answer: Internal migration.

The residence changes across a state boundary but stays within Australia. That is interstate migration, a type of internal migration. The relevant boundary and usual residence matter; citizenship need not change.

Easy

15. A family is forced from home by flooding but remains within its country’s internationally recognized borders. Which term fits this displacement?
Show answer

Correct answer: Internal displacement.

They are internally displaced people. Forced movement within a country does not by itself make someone a refugee under the international refugee definition.

Hard

16. For a person with a nationality, which situation matches the core 1951 Refugee Convention criteria, assuming no exclusion clause applies?
Show answer

Correct answer: Outside their country of nationality, with a well-founded fear of persecution on a Convention ground and unable or unwilling because of that fear to seek its protection.

Convention grounds include race, religion, nationality, membership of a particular social group and political opinion. Regional definitions can be broader. Recognition confirms refugee status rather than creating it.

Medium

17. Someone has applied for international protection and is awaiting a final decision. What does describing them as an asylum-seeker establish?
Show answer

Correct answer: They seek protection; the label alone does not settle their refugee status.

A pending claim is not a decision on eligibility. Some asylum-seekers meet refugee criteria, while others ultimately will not be recognized.

Hard

18. Two households face similar wage gaps between home and a possible destination, but only one can afford travel and obtain permission to move. What does this show about a simple push–pull explanation?
Show answer

Correct answer: Opportunities alone are insufficient; resources and constraints shape who can move.

Reasons to move are not the same as the ability to move. Money, policy and social ties can enable or restrict movement. Lived constraints also complicate a simple voluntary-versus-forced binary, without erasing distinct legal protection categories.

Medium

19. Earlier migrants help friends from their home region find housing and work in the same destination. Which process does this most clearly illustrate?
Show answer

Correct answer: Chain migration through social networks.

Existing social ties can pass on information and practical help, lowering barriers for later movers. This is the network mechanism behind chain migration; the defining clue is help passed from earlier to later movers.

Easy

20. A person living abroad regularly sends money to a household in their country of origin, without buying goods or acquiring ownership. Which label best fits the transfer?
Show answer

Correct answer: A personal remittance.

This is a household-to-household personal transfer. Such transfers are part of the World Bank’s personal-remittances measure, which also includes compensation of employees. Remittances can be cash or in kind and are distinct from aid or investment.

  • Check what is being divided. Total land, arable land, the whole population and a specified age group answer different questions. A percentage is not an absolute count.
  • Separate the components of change. Births minus deaths give natural change. Arrivals minus departures give net migration. A positive value for one component can be outweighed by a negative value for the other.
  • Read models as conditional explanations. Age structure matters, replacement fertility varies, and constant-growth doubling time is an approximation. None is a guaranteed forecast for a real place.
  • Keep movement and protection categories precise. Stocks differ from flows, internal moves differ from international ones, and displacement does not automatically establish refugee status. Social ties, resources and restrictions also shape who can move.

What Did We Learn Today?

Population geography depends on choosing the right denominator, time period and geographic boundary. Age structure helps explain why fertility and mortality measures do not translate directly into immediate population growth or decline. Migration adds another component of change, but its stocks, flows and net balance measure different things. Understanding movement also means recognizing both people’s choices and their constraints, while keeping legal protection definitions precise.

Sources & Data Notes

All numerical examples and described scenarios are hypothetical practice exercises, not reported country statistics. Age dependency uses ages 0–14 and 65+ relative to ages 15–64; it does not measure actual financial dependency. The refugee question specifies the 1951 Convention, while regional definitions and other protection frameworks can be broader. Sources support stable concepts rather than current rankings. Difficulty levels are editorial, not a standardized assessment.
