Is Mexico City the Largest City in the United States? True or False

The statement that Mexico City is the largest city in the United States is false. Mexico City is the capital and most populous city of Mexico, a sovereign nation separate from the United States. Geographically and politically, it lies entirely outside U.S. borders.

The largest city in the United States by population is New York City, followed by Los Angeles and Chicago. Mexico City, however, ranks among the largest metropolitan areas in the world, with a population exceeding 21 million in its greater metropolitan area.
