This is why China's gross domestic product (GDP) ranks second in the world, while its per capita GDP is above 100, because there are too many people in China.

Please note, however, that since this is the gross domestic product (GDP), anyone in China, regardless of nationality, should be included. This is the opposite of gross national product (GNP). As the name implies, "national" in GNP refers to all people with China nationality, no matter where they are.
