The United States Minor Outlying Islands is a statistical designation applying to the minor outlying islands and groups of islands that comprise eight United States insular areas and territories in the Pacific Ocean (Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Palmyra Atoll, and Wake Island) and one in the Caribbean Sea (Navassa Island).
It is defined by the International Organization for Standardization's ISO 3166-1 code. The entry code is ISO 3166-2:UM.
While the islands scattered across Polynesia and Micronesia are relatively small, they are strategically important and are rich in history and nature. The nearly barren Howland is famous for being the island renowned American pilot Amelia Earhart intended to land on before she vanished during her round-the-world flight in 1937. Wake, home to a now extinct flightless bird, was the site of a pitched World War II battle in 1941, and was an essential stopover for aircraft transiting the Pacific in the mid-20th century. Likewise, Midway Atoll is home to many corals and birds and was also the center of a major battle of WWII, which helped turn the tide of the Pacific War. Other islands are rich in unique biodiversity, such as Palmyra, the site of a WWII base. Johnston Atoll was a famous island for its Cold War base, when it was expanded and used to destroy chemical weapon stockpiles; it was also the site of a nuclear accident. Johnston was heavily modified with land expansion, while others are nearly untouched nature reserves.
History
In 1936, a colonization program began to settle Americans on Baker, Howland, and Jarvis islands. All were evacuated in 1942 due to World War II.
The International Organization for Standardization (ISO) introduced the term "United States Minor Outlying Islands" in 1986. From 1974 until 1986, five of the islands (Baker Island, Howland Island, Jarvis Island, Palmyra Atoll, and Kingman Reef) were grouped under the term United States Miscellaneous Pacific Islands, with ISO 3166 code . The code of Midway Atoll was , the code of Johnston Atoll was , and the code of Wake Island was . Before 1986, Navassa Island, along with several small islands in the Caribbean Sea that are no longer under U.S. sovereignty, were grouped under the term United States Miscellaneous Caribbean Islands, with FIPS country code .
The populated Stewart Islands, called Sikaiana and now effectively controlled by the Solomon Islands, are not included in official lists of U.S. Minor Outlying Islands. In 1856, the Kingdom of Hawaii Privy Council and King Kamehameha IV voted to accept their voluntary cession. The Kingdom later became the Republic of Hawaii, all of which was annexed by the United States in 1898. In 1959, the resulting federal U.S. Territory of Hawaii, excluding only Palmyra Atoll and Midway Atoll, became a U.S. state. Residents of the Stewart Islands, who are Polynesian like the native Hawaiians rather than Melanesian, claimed to be citizens of the United States since the Stewart Islands were given to King Kamehameha IV in 1856 and were part of Hawaii at the time of the United States annexation in 1898. The U.S. federal and Hawaii state governments informally accept the recent claim of the Solomon Islands over the Stewart Islands, and the United States makes no official claim of sovereignty.
Overview

Except for Palmyra Atoll, all of these islands are unincorporated unorganized territories of the United States. Currently, none of the islands have any known permanent residents. However, military personnel, U.S. Fish and Wildlife Service personnel, and temporarily stationed scientific and research staff are posted to some islands. The 2000 census counted 315 people on Johnston Atoll and 1 person on Wake Island. The Territory of Palmyra Atoll is an incorporated territory, separated in 1959 from the rest of the former incorporated Territory of Hawaii when Hawaii became a state.
There has been no recorded modern Indigenous population, except at the 1940 census. During the late 2010s, the U.S. military began reinvesting in the airfield and other assets on Wake Island.
The islands are grouped for statistical convenience. They are neither administered collectively nor share a single cultural or political history beyond being uninhabited islands under the sovereignty of the United States. They are all outside the customs territory of the United States and have no customs duties. Except for Midway Atoll, the Pacific islands are surrounded by large exclusive economic zones and are within the bounds of the Pacific Islands Heritage Marine National Monument.
They are collectively represented by the ISO 3166-1 alpha-2 code UM. The individual islands have ISO 3166-2 numerical codes.
The Internet country code top-level domain (ccTLD) ".um" has historically been assigned to the islands; however, the .um ccTLD was retired in January 2007.
Most of the U.S. Minor Outlying Islands islands are closed to the public. Visitors to islands such as Jarvis Island need a permit. Palmyra Atoll is open to the public, but there is no easy way to reach it.
