Context paragraphs:
Northwestern Hawaiian Islands: The Northwestern Hawaiian Islands or the Leeward Islands are the small islands and atolls in the Hawaiian island chain located northwest (in some cases, far to the northwest) of the islands of Kauai and Niihau.  Politically, they are all part of Honolulu County in the U.S. state of Hawaii, except Midway Atoll, which is grouped as one of the United States Minor Outlying Islands.  The United States Census Bureau defines this area, except Midway, as Census Tract 114.98 of Honolulu County.  Its total land area is 3.1075 sqmi .  All the islands except Nihoa are north of the Tropic of Cancer, making them the only islands in Hawaii that lie outside the tropics.

Howland Island: Howland Island is an uninhabited coral island located just north of the equator in the central Pacific Ocean, about 1700 nmi southwest of Honolulu.  The island lies almost halfway between Hawaii and Australia and is an unincorporated, unorganized territory of the United States.  Geographically, together with Baker Island it forms part of the Phoenix Islands.  For statistical purposes, Howland is grouped as one of the United States Minor Outlying Islands.

Midway Atoll: Midway Atoll ( ; also called Midway Island and Midway Islands; Hawaiian: "Pihemanu Kauihelani") is a 2.4 sqmi atoll in the North Pacific Ocean at .  As its name suggests, Midway is roughly equidistant between North America and Asia.  Midway Atoll is an unorganized, unincorporated territory of the United States.  Midway continues to be the only island in the Hawaiian archipelago that is not part of the state of Hawaii.  Unlike the other Hawaiian islands, Midway observes Samoa Time (, i.e., eleven hours behind Coordinated Universal Time), which is one hour behind the time in the state of Hawaii.  For statistical purposes, Midway is grouped as one of the United States Minor Outlying Islands.  The Midway Atoll National Wildlife Refuge, encompassing 590991.50 acre of land and water (mostly water) in the surrounding area, is administered by the United States Fish and Wildlife Service (FWS).  The refuge and most of its surrounding area are part of the larger Papahānaumokuākea Marine National Monument.

United States Minor Outlying Islands: The United States Minor Outlying Islands, a statistical designation defined by the International Organization for Standardization's ISO 3166-1 code, consist of eight United States insular areas 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).

Line Islands: The Line Islands, Teraina Islands or Equatorial Islands, is a chain of atolls (with partially or fully enclosed lagoons) and coral islands (with a surrounding reef).  Kingman Reef is a largely submerged and Filippo Reef is shown on some maps, although its existence is doubted.  The islands were formed by volcanic activity and are located in the central Pacific Ocean, south of the Hawaiian Islands.  The 11 islands stretch for 2,350 km in a northwest–southeast direction, making it one of the longest island chains of the world.  Eight of the islands form part of Kiribati, while the remaining three are United States territories grouped with the United States Minor Outlying Islands.  Only Kiritimati and Tabuaeran atolls and Teraina Island have a permanent population.

.um: . um was the Internet country code top-level domain for the United States Minor Outlying Islands.  It was administered by the United States Minor Outlying Islands Registry.  Until late 2006 USMIR was housed at the University of Southern California Information Sciences Institute (USC-ISI), which was the original administrator of . us prior to NeuStar absorbing that role.

Wake Island: Wake Island (also known as Wake Atoll) is a coral atoll in the western Pacific Ocean in the northeastern area of the Micronesia subregion, 1,501 mi east of Guam, 2,298 mi west of Honolulu and 1,991 mi southeast of Tokyo.  The island is an unorganized, unincorporated territory of the United States Minor Outlying Islands that is also claimed by the Republic of the Marshall Islands.  Wake Island is one of the most isolated islands in the world and the nearest inhabited island is Utirik Atoll in the Marshall Islands, 592 mi to the southeast.

Johnston Island Air Force Base: Johnston Island Air Force Base is a former United States Air Force base on the Johnston Atoll in the United States Minor Outlying Islands, in the Pacific Ocean several hundred kilometers southwest of Hawaii.  After its closure, it briefly operated as Johnston Atoll Airport, until its closure in 2005.

List of islands of Hawaii: The following is a list of islands of Hawaii.  The state of Hawaii, consisting of the Hawaiian Islands, has the fourth-longest ocean coastline of the 50 states (after Alaska, Florida, and California) at 750 miles (1,210 km).  It is the only state that consists entirely of islands with 6,422.62 mi² (16,635 km²) of land.  The Hawaiian Island archipelago extends some 1,500 miles (2,400 km) from the southernmost island of Hawaiʻi to the northernmost Kure Atoll.  Despite being within the boundaries of Hawaii, Midway Atoll, comprising several smaller islands, is not included as an island of Hawaii, because it is classified as a United States Minor Outlying Islands and is therefore administered by the federal government and not the state.

Hawaiian Islands: The Hawaiian monarchy was overthrown in 1893 and the United States annexed the islands in 1898.  The U.S. state of Hawaii now occupies the archipelago almost in its entirety (including the uninhabited Northwestern Hawaiian Islands), with the sole exception of Midway Island, which instead separately belongs to the United States as one of its unincorporated territories within the United States Minor Outlying Islands.
