Population Explosion: The U.S. population has grown by more than 13,000 percent since the nation declared independence.
1776: 2.5 million people* / 2025: 342 million people. *The first U.S. Census wasn’t conducted until 1790, so population data for the year 1776 is estimated. Indigenous populations weren’t included in the Census then, but hundreds of thousands of Indigenous people lived in the territory at the time.
