GDP per Capita Quiz

How to play

1. Two countries appear side by side (stacked on a phone). The first shows its GDP per person; 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

Population is the trap. China and India have huge economies and middling figures per person, while Luxembourg, Ireland, Switzerland and several Gulf states sit at the top. Small financial and resource economies score higher than their visibility suggests. Ireland’s figure is inflated by multinationals booking profits there.

An average, not a typical pay cheque

GDP per person divides economic output by population. It is not a wage, household income or the amount paid to every resident. Two countries with similar averages can have very different income distributions.

This game uses current US dollars, so exchange rates and local price levels affect how the comparison should be interpreted. It is not adjusted for purchasing power. A useful strategy is to think about output per resident instead of recalling which countries have the largest total economies.

How this measure is defined

Gross domestic product divided by population, in current US dollars converted at market exchange rates. Exchange-rate conversion makes countries with weak currencies look poorer than a purchasing-power comparison would. It is an average, so it says nothing about how that income is distributed.
