Example comparison
UNITED STATES VS CHINA
The United States and China are useful to compare because both sit near the top of total GDP rankings, but their economic scale rests on very different population bases.
GDP makes the two countries look like peer economic systems; population and GDP per capita immediately change that picture. The map helps separate total output from the number of people behind it.
What the data reveals
The comparison changes when the denominator changes
- Nominal GDP puts the United States at about 1.6 times China in this snapshot, while China has about 4.1 times the population.
- That denominator changes the result: United States GDP per person is about 6.5 times China, even though their total GDP figures are much closer.
- Purchasing-power GDP reverses the nominal order, with China about 1.3 times the United States. Their measured land areas differ by only about 0.7%, so territory alone does not explain the economic contrast.

Why one headline ranking is not enough
Viewed only as a table, GDP, population and area can feel like separate facts. On the map, the contrast is easier to read: China has much more population, the United States has higher GDP per person, and land area does not explain the economic gap by itself.
This pair was chosen because it is a familiar headline comparison, but it becomes more useful when you switch metrics instead of treating one ranking as the whole story.
Keep the countries fixed and switch the metric
The preset opens with nominal GDP and places the United States in Group A and China in Group B. Keep that selection while switching to population, purchasing-power GDP, GDP per capita, density or land area to reproduce each contrast discussed above.
