That's a LOT of people!
I was just over 1 year old when the U.S. population hit 200 million on Nov. 20, 1967. Now, less than a month before my 40th birthday, we have reached a new milestone.
According to an Associated Press article, the nation's population officially hit 300 million at 7:46 a.m. EDT Tuesday, when the Census Bureau's population clock rolled over to the big number.
I wonder what year it will be when we hit 400 million? And what new problems that will bring?
