The Greeks or Hellenes (Έλληνες) are an ethnic group native to Greece, Cyprus, Albania, Anatolia, Southern Italy, and other regions. They also form a significant diaspora, with Greek communities established around the world. Greek colonies and communities have been historically established on the shores of the Mediterranean Sea and Black Sea, but the Greek people have always been centered around the Aegean and Ionian seas, where the Greek language has been spoken since the Bronze Age. Until the early 20th century, Greeks were distributed between the Greek peninsula, the western coast of Asia Minor, the Black Sea coast, Cappadocia in central Anatolia, Egypt, the Balkans, Cyprus, and Constantinople. Many of these regions coincided to a large extent with the borders of the Byzantine Empire of the late 11th century and the Eastern Mediterranean areas of ancient Greek colonization. The cultural centers of the Greeks have included Athens, Thessalonica, Alexandria, Smyrna, and Constantinople at various periods. Most ethnic Greeks live nowadays within the borders of the modern Greek state and Cyprus. The Greek genocide and population exchange between Greece and Turkey nearly ended the three millennia-old Greek presence in Asia Minor. Other longstanding Greek populations can be found from southern Italy to the Caucasus and southern Russia and Ukraine and in the Greek diaspora communities in a number of other countries. Today, most Greeks are officially registered as members of the Greek Orthodox Church.CIA World Factbook on Greece: Greek Orthodox 98%, Greek Muslim 1.3%, other 0.7%. Greeks have greatly influenced and contributed to culture, arts, exploration, literature, philosophy, politics, architecture, music, mathematics, science and technology, business, cuisine, and sports, both historically and contemporarily.

Retrieved July 2, 2008. Utah is the most religiously homogeneous state in the United States, the only state with a Mormon majority, and the only state with a majority population belonging to a single church. The state is a center of transportation, education, information technology and research, government services, mining, and a major tourist destination for outdoor recreation. In 2013, the U.S. Census Bureau estimated that Utah had the second fastest-growing population of any state. St. George was the fastest–growing metropolitan area in the United States from 2000 to 2005.
