Emigration from the United States is the process where citizens from the United States move to live in other countries, creating an American diaspora (overseas Americans). The process is the reverse of the immigration to the United States. The United States does not keep track of emigration, and counts of Americans abroad are thus only available based on statistics kept by the destination countries.
Due to the flow of people back and forth between the United Kingdom and its colonies, as well as between the colonies, there has been an American diaspora of a sort since before the United States was founded. During and immediately after the American Revolutionary War, a number of American Loyalists relocated to other countries, chiefly Canada and the United Kingdom. Residence in countries outside the British Empire was unusual, and usually limited to the wealthy, such as Benjamin Franklin, who was able to self-finance his trip to Paris as a U.S. diplomat.
