Honolulu is the capital and largest city of the U.S. State of Hawaii. In the Hawaiian language, honolulu means "sheltered bay" or "place of shelter." The census-designated place (CDP) is located along the southeast coast. The term also refers to the District of Honolulu (see Geography below). As of July 1, 2004, the United States Census Bureau estimate for Honolulu puts the population at 377,260 and that of the city and county (essentially, the Island of Oʻahu) at 900,000. In Hawaii, local governments operate only at the county level, and the City & County of Honolulu encompasses all of the Island of Oʻahu (approximately 600 square miles).
