Population Game: Higher or Lower

How to play

1. Two countries appear side by side (stacked on a phone). The first shows its population; the second keeps its value hidden.
2. Decide whether the second one is higher or lower and press Higher or Lower.
3. The hidden value counts up and your answer is judged. When you are right, the second card moves across and a new one takes its place.
4. One wrong answer ends the run. There is no timer, and values stay fixed for the whole run. Countries without a value for this measure sit out, and two countries whose values read the same are never paired.
5. Your result is saved in this browser. Once enough people have played a game, the results also show how your score ranks, and you can copy or share an image of your result, or replay.

Understanding the comparison

Land area is the trap: Canada, Australia and Kazakhstan are vast and thinly populated, while Bangladesh, the Philippines and Vietnam pack far more people into far less space. Nigeria and Ethiopia are larger than most people guess, and Egypt outweighs every other country in its region.

Population is not population density

This game compares the total number of residents. A densely settled small country can contain fewer people than a much larger, more sparsely populated country. Neither the size of its flag nor the apparent size of its map tells you the answer.

Try separating your estimate into land area and how intensively it is inhabited. This is a memory aid, not a calculation: deserts, mountain ranges and major urban regions make average density uneven. The year below matters because the answer is a dated population estimate, not a live headcount.

How this measure is defined

The value counts everyone resident in the country during the reference year, regardless of citizenship. It is a mid-year estimate compiled from censuses and registers rather than a live count, and it is a total rather than a density, so it says nothing about how crowded a country feels.

Everyone resident in the country during the reference year, regardless of citizenship. This is a mid-year estimate, not a live count or a land measurement.

The collection date tells you when we retrieved the source, not when every underlying observation was made. A failed refresh does not advance that date. For comparisons, the snapshot loaded for your run supplies the answers.
