The Question: After China, India, and the U.S., what is the most populous nation?
China and India each have more than 1.3 billion people — to put that huge number into perspective, if each lost a billion people, they would still be the two most populous countries in the world. After those two Asian giants comes the United States, with a comparatively paltry 330 million residents. In fourth place overall is the archipelagic nation of Indonesia, with 273 million inhabitants.
The correct answer is Indonesia.
