Population

Citizenship
With very few exceptions, persons who are born in the United States become American citizens regardless of their ethnic backgrounds or of the citizenship and national origins of their parents. In this respect, the United States differs from many other countries that do not automatically confer citizenship on persons merely on the basis of birth within their national jurisdictions. Open acceptance has characterized the American nationality process since the nation's founding, despite changes to laws and regulations over the years.

Did you know?
The first census of the United States was authorized by act of Congress on March 1, 1790, "providing for the enumeration of the inhabitants of the United States." The U.S. population was 80 million in 1902 and 298 million+ on Census Day, April 1, 2006. In 1803, the United States paid France $15 million for the Louisiana Territory — 828,000 square miles of land west of the Mississippi River. The lands acquired stretched from the Mississippi to the Rockies and from the Gulf of Mexico to the Canadian border. The Louisiana Purchase nearly doubled the size of the United States and contained area from which all or part of 13 states were eventually carved.
