What percent of the world's population lives in the United States?

The correct answer is that approximately 4% of the world's population lives in the United States. This figure is drawn from the total world population, which is estimated to be around 8 billion people as of late 2023. With the population of the United States being roughly 330 million, this translates to about 4% of the global population. It's important to remember that demographic statistics can fluctuate slightly based on current population counts and estimates, but the commonly accepted percentage is around 4%.

This means that while other options suggest a higher percentage, they do not align with the actual demographic data regarding the distribution of the global population. Understanding these statistics is crucial for contextualizing discussions about economics, politics, and social issues at both national and international levels.
