America at 300 Million: Breaking Down the Numbers
An Informal Poll
Estimates on how many people live in the United States vary widely on the National Mall.
In 1790, the U.S. population was just shy of 4 million people. By 1915, the population had reached 100 million.
Immigration, the post-war baby boom, longer life expectancies and better medical care doubled the population by 1967. Just 33 years later, we've reached a new milestone: 300 million.
Here are just a few glimpses into American life at 100, 200, and 300 million people.
