arguments, technical snarls – News". Virgin Islands Daily News. Retrieved April 8, 2013. On November 3, 2020, the Virgin Islands held a referendum on whether to convene a sixth constitutional convention. The proposal was approved with nearly 72% voting in favor. Administrative divisions Administratively, the U.S. Virgin Islands are divided into two districts: the St. Thomas and St. John district, and the St. Croix district. However, the U.S. Census Bureau divides each of the three main islands into three separate statistical entities (which are further divided into 20 subdistricts). Below is the U.S. Census Bureau's division model. Each of the three main islands of the U.S. Virgin Islands is counted as a county equivalent by the U.S. Census Bureau, with the following FIPS codes: 78010 for St. Croix, 78020 for St. John, and 78030 for St. Thomas. While a Danish possession, the islands were divided into "quarters" (five on St. John and nine on St. Croix), which were further divided into many dozens of "estates". Estate names are still used to write addresses; estates and quarters are used in describing real estate, especially on St. John and St. Croix. More densely populated towns such as Frederiksted and Christiansted on St. Croix were historically referred to as "districts", in contrast to the surrounding plantation land. Political status A 1993 referendum on status attracted only 31.4% turnout, and so its results (in favor of the status quo) were considered void. No further status referendums have been scheduled since. The territory is classified by the United Nations as a non-self-governing territory. In 2016, the United Nations' Special Committee on Decolonization recommended to the UN's General Assembly that this larger body should "actively pursue a public awareness campaign aimed at assisting the people of the United States Virgin Islands with their inalienable right to self-determination and in gaining a better understanding of the options for self-determination". Governors of the U.S. Virgin Islands Law enforcement Law enforcement services are provided by the United States Virgin Islands Police Department (USVIPD). Military Defense is the responsibility of the United States. There are some military facilities and personnel on the islands, supported by the U.S. government: United States Army Reserve Virgin Islands National Guard Virgin Islands Air National Guard — stationed at St. Croix ANGS Virgin Islands Army National Guard — stationed at St. Croix ANGS Lionel A.
