The 20 questions

  1. What is the population threshold for a city to count as a megacity?

    • More than 100,000 people
    • More than 1 million people
    • More than 10 million people
    • More than 50 million people

  2. Roughly how many megacities were there in 1950?

    • Fifty
    • Twenty
    • None
    • Two

  3. Roughly how many megacities are there today?

    • Fewer than five
    • About ten
    • More than 30
    • More than 300

  4. Which city has a population of about 37 million people, making it one of the largest megacities in the world?

    • Delhi
    • Norwich
    • Lagos
    • Tokyo

  5. Is Norwich, with about 0.2 million people, a megacity?

    • No, it is far below 10 million people
    • Yes, because it is in the United Kingdom
    • It depends on the number of tourists each year
    • Yes, because it has a famous cathedral

  6. Which of these cities has over 15 million people?

    • Norwich
    • Sydney
    • Santiago
    • Lagos

  7. What does a proportional-symbol map show?

    • The height of mountains shown with coloured shading
    • The depth of the ocean shown in metres
    • The average temperature for each season
    • Data size shown through the size of the symbol

  8. On a proportional-symbol map, what does a bigger circle show?

    • A greater distance from the equator
    • A bigger population
    • A higher price of food
    • A colder climate

  9. Which continent contains the cluster of the largest megacity symbols?

    • Australia
    • Antarctica
    • Asia
    • Europe

  10. Which of these best describes clustering in a distribution?

    • Symbols that all have the same size
    • Symbols placed randomly with no pattern at all
    • Symbols grouped tightly together in one area
    • Symbols that appear only on the edge of the map

  11. What is an anomaly in a distribution?

    • A line showing the average population
    • A place that does not fit the general pattern
    • A legend that explains each symbol
    • The most common pattern on the whole map

  12. Which is a sound way to describe a distribution?

    • Describe only the colours used on the map
    • Say they are everywhere, then list the largest cities one by one with no reference to the map
    • List every city alphabetically with no pattern
    • Give the general pattern, describe clustering, quote evidence, then name an anomaly

  13. Why is Australia described as an anomaly in the megacity pattern?

    • It has no megacity symbols despite being a large continent
    • It has the largest population of any continent
    • It has more megacities than any other continent
    • It is covered in ice all year round

  14. Why are cities growing fastest in Asia and Africa?

    • Governments there have banned all births in cities, so growth can only come from rural migration
    • Industrial jobs pull people in, and young populations have high birth rates
    • Cities in Asia and Africa cannot offer any jobs at all
    • Rich countries are sending all their people to Asia

  15. Why do European cities grow slowly today?

    • Europe urbanised about a century ago, so its cities now grow slowly
    • European cities are banned from accepting migrants, so every city has a fixed and unchanging population
    • European cities are banned from accepting migrants
    • Europe has more megacities than Asia each decade

  16. Roughly how many people does Lagos grow by each year?

    • About 500,000
    • About 5 million
    • About 50,000
    • About 5,000

  17. Urban population (millions): Asia 1,000 (1990), 1,750 (2010), 3,300 (2035); Africa 200, 400, 900; Europe 500, 530, 580. Which region's urban population rises the most in absolute terms?

    • Asia
    • Europe
    • Africa
    • All three rise by the same amount

  18. Europe's urban population (millions) was 500 in 1990 and 530 in 2010. By how much did it rise?

    • About 530 million
    • About 30 million
    • About 3 million
    • About 300 million

  19. Which reason best explains the megacity cluster in South and East Asia?

    • Governments in Asia forbid rural people from moving to cities
    • Industrialisation brings factory jobs and there are many large, young populations
    • Megacities there are only tourist resorts with no residents
    • The climate there prevents people from living in the countryside, so every family is forced to move into cities

  20. Which statement best evaluates migration against natural increase in city growth?

    • Both forces stop once a city passes 10 million people
    • Natural increase is the only reason any city grows
    • Migration never affects city size at all, because newcomers always leave again after a single year
    • Both matter: migration brings people in, while natural increase grows the city from within
