Greek Americans are Americans of full or partial Greek ancestry. They number at least 1.2 million, of whom 264,066 (22%) over the age of five speak Greek at home.
The United States is home to the largest number of Greeks outside Greece, followed by Cyprus and Australia. Greek Americans have the highest concentrations in New York City, Boston, and Chicago, but have settled in major metropolitan areas across the United States. In 2000, Tarpon Springs, Florida, was home to the largest community of Greek Americans proportionally, at just over 10%.
