The address of the White House is 1600 Pennsylvania Avenue. The address of the White House serves as the residence of the president.
You can think of the address of the White House in different ways. The first way is the actual physical address of the white house, which is 1600 Pennsylvania Avenue. The site for the White House was chosen by George Washington and Pierre L'Enfant, the designer for the city of Washington D.C. Construction of the mansion at 1600 Pennsylvania Avenue did not begin until the fall of 1792.
The second context in which the address of the white house is often taken is in the form of a speech. This address to the people of the United States is also known as a Presidential address. This is because the entity of the President and the White House are often interchangeable entities. Anything that comes from the "White House" or the address of the White House as in "Pennsylvania Avenue" is also usually interpreted to mean that the information, quote or information is coming from the President of the United States. The reason that the building and the President are so inextricably entwined is because every single President since John Adams has made the large white mansion on Pennsylvania Avenue his home. Although many people believe that every president has lived in the White House; George Washington served as prior during the construction of the White House and thus did not actually live there.
Depending on who the president is and what his style of relating to the people is, an address of the White House can happen once a year or it can happen once a week. Contemporary presidents such as George Bush prefer to make an address of the White House at least once a week. Usually this address is televised nationally and after the speech the president is quizzed in a question and answer session by reporters.
