Fisher Island is a census-designated place of metropolitan Miami, Florida, located on a barrier island of the same name. As of the 2010 census, Fisher Island had the highest per capita income of any place in the United States. The CDP had only 226 households and a total population of 132 persons. A relatively small part of the northern part of the island is incorporated as a part of the city of Miami Beach.
Named for automotive parts pioneer and beach real estate developer Carl G. Fisher, who once owned it, Fisher Island is three miles off shore of mainland South Florida. No road or causeway connects to the island, which is accessible by private boat or ferry. Once a one-family island home of the Vanderbilts, and later several other millionaires, it was sold for development in the 1960s. The property sat vacant for well over 15 years before development was begun for very limited and restrictive multi-family use.
