Overview

Overview

American Samoa at a glance

Settled as early as 1000 B.C., Samoa was not reached by European explorers until the 18th century. International rivalries in the latter half of the 19th century were settled by an 1899 treaty in which Germany and the US divided the Samoan archipelago. The US formally occupied its portion - a smaller group of eastern islands with the excellent harbor of Pago Pago - the following year.

National Infrastructure

🇦🇸 American Samoa’s critical and strategic infrastructure, sustaining output, agility and endurance

The National Infrastructure Index maps the physical assets national life runs on — power stations and grids, water systems, ports, railways and airports, data networks, payment systems and launch sites. Each asset is placed in a Strategic Infrastructure capability group, so it can be read against the ratings in the National Capability index above.

Assets are chosen for how much of the economy and state depends on them and how hard they would be to replace. Each card records what the asset is, the category it belongs to, what it does and where it is.

National Developments

🇦🇸 American Samoa’s major milestones and key developments

The National Development Index tracks the events that move a nation's capability — policy decisions, technological milestones, economic turns and external shocks — and places each one on the record with the date it happened and what followed from it. It is the narrative counterpart to the indices: where a rating says where American Samoa stands, the index says how it arrived there.

Recent developments cover the current cycle, close enough that their consequences are still unfolding. Historical developments are the inflection points behind the present position — the decisions and events a reader needs in order to read the ratings above in context.

Historical Developments

1000 B.C.Polynesian voyagers settled the Samoan islands 3026 years ago

Samoa was settled as early as 1000 BC by Austronesian peoples, making it one of the earliest inhabited island groups of Polynesia.

18th centuryEuropean explorers reached Samoa 326 years ago

Although settled for millennia, Samoa was not visited by Europeans until the 18th century, when Dutch and French navigators sighted the islands.

1722Jacob Roggeveen became the first known European to sight the Samoan Islands 304 years ago

The Dutch navigator Roggeveen sighted the archipelago and named it the Baumann Islands after one of his captains. This marked the beginning of recorded European contact with a group inhabited by Polynesians since prehistoric times.

1768Louis-Antoine de Bougainville visited and named the group the Îles des Navigateurs 258 years ago

The French explorer was the next European to reach the Samoan Islands after Roggeveen. His naming of the islands fixed them on European charts and drew further Pacific expeditions towards the archipelago.

1773James Cook recorded the island names without landing 253 years ago

The British explorer noted the Samoan island names in his records but never visited the group. The entry added the islands to British navigational knowledge of the Pacific.

December 1784Lapérouse landed two exploration parties on Tutuila 242 years ago

The French navigator put parties ashore from the Boussole at Fagasā and from L'Astrolabe at Aʻasu on Tutuila's north shore. It was among the earliest recorded European landings on the island that would become the territory's centre.

1789Lapérouse's expedition lost its second-in-command in the Massacre Bay killings on Tutuila 237 years ago

While attempting to obtain water on Tutuila, Captain de Langle, the scientist Robert de Lamanon and several crew were surrounded by over a thousand Samoans and killed. Lapérouse named the island Massacre Island, and the bay near Aasu still bears the name, shaping European perceptions of Samoa for decades.

1791HMS Pandora under Admiral Edward Edwards visited Tutuila while hunting the Bounty mutineers 235 years ago

The Royal Navy vessel called at the island during its Pacific search for the mutineers of HMS Bounty. The visit reflected the islands' growing position on naval routes through the South Pacific.

1830John Williams of the London Missionary Society began Christian mission work in the Samoas 196 years ago

Williams arrived from the Cook Islands and Tahiti in late 1830 to begin missionary activity. Christianity became overwhelmingly dominant in Samoan society, a religious character the territory retains.

1839The United States Exploring Expedition surveyed the Samoan Islands 187 years ago

The American expedition visited the islands as European and American vessels increasingly used Pago Pago Harbor as a coaling and whaling stop. The visit marked early United States interest in the archipelago's strategic harbour.

February 1872Commander Richard W. Meade and High Chief Mauga agreed exclusive US naval station rights at Pago Pago 154 years ago

Meade sailed the USS Narragansett from Hawaiʻi to Pago Pago, tasked by the US minister to Hawaiʻi with securing American interests. Mauga granted the United States exclusive rights to build and maintain a naval station in exchange for American friendship and protection, and Meade also set commercial port regulations. This was the foundation of the American presence at Pago Pago Harbor.

March 1889American and German naval forces faced off at Apia until a typhoon wrecked both fleets 137 years ago

An Imperial German naval force destroyed American property in a Samoan village, and three American warships confronted three German warships in Apia harbour. A typhoon wrecked the ships of both sides before shots were fired, forcing a compulsory armistice and underscoring the great-power rivalry over Samoa.

1899Germany and the United States partitioned the Samoan Islands under the Tripartite Convention 127 years ago

The convention divided the archipelago, with the eastern group passing to the United States and the western islands becoming German Samoa, while Britain abandoned its Samoan claims in exchange for German concessions in Tonga, the Solomons and West Africa. It followed the Washington Conference of 1887, the Treaty of Berlin of 1889 and the Anglo-German Agreement on Samoa. The partition created the enduring division between American Samoa and Samoa.

1900The United States Navy secured the Deed of Cession of Tutuila and formally annexed the eastern islands 126 years ago

After taking possession of eastern Samoa, the Navy obtained a Deed of Cession from Tutuila's chiefs on behalf of the US government and expanded the coaling station at Pago Pago Bay into United States Naval Station Tutuila. The cession remains the legal foundation of American Samoa's relationship with the United States, and 1900 also fixed the baseline for freehold land ownership.

1904Tui Manuʻa Elisala signed the Deed of Cession of Manuʻa as its last sovereign 122 years ago

The last Tui Manuʻa ceded the Manuʻa group following a series of US naval trials known as the Trial of the Ipu, held in Pago Pago, Taʻu and aboard a Pacific Squadron gunboat. The cession completed American possession of the eastern Samoan islands and ended an ancient paramountcy.

July 1911The US Navy officially renamed the territory American Samoa 115 years ago

After Governor William Michael Crose conveyed Manuʻan resentment at being excluded from the name Naval Station Tutuila, the Navy Department invited the people to choose a name, and traditional leaders selected American Samoa. The solicitor general of the Navy authorised the proclamation on 7 July and it took effect on 17 July 1911, giving the territory its enduring identity.

1918Governor John Martin Poyer imposed quarantine and prevented any influenza deaths 108 years ago

Hearing radio reports of the pandemic, Poyer requested quarantine ships from the US mainland and sealed the territory, making American Samoa one of very few places worldwide with no influenza deaths. Neighbouring Western Samoa lost around 20 per cent of its population; Poyer was awarded the Navy Cross and regarded locally as a hero.

1920sSamuelu Ripley and the American Samoa Mau led a protest movement suppressed by the US Navy 106 years ago

Echoing the Mau movement in New Zealand-administered Western Samoa, a World War I veteran from Leone village organised opposition in American Samoa after meetings on the US mainland. He was barred from disembarking on his return and the movement was suppressed by the Navy, though the agitation kept the territory's status in question.

June 1922Tutuila saw the start of its first bus service 104 years ago

The island's first bus operations began on 8 June 1922. It marked the beginning of organised public land transport on the territory's main island.

August 1924Margaret Mead arrived to begin the fieldwork behind Coming of Age in Samoa 102 years ago

Mead reached American Samoa aboard the SS Sonoma to conduct fieldwork for her Columbia University doctorate under Franz Boas. Her resulting 1928 book became the most widely read work in anthropology at the time, projecting American Samoa into global intellectual debate.

1925The United States annexed Swains Island to American Samoa 101 years ago

Swains Island, previously listed among the guano islands appertaining to the United States under the Guano Islands Act, was annexed by Public Resolution 68–75. The annexation followed the United Kingdom's dissolution of the Gilbert and Ellice Islands Protectorate and extended the territory's reach northwards.

1929The United States vested territorial powers in the President under the Ratification Act of 1929 97 years ago

The Act classified American Samoa as an unincorporated territory and vested all civil, judicial and military powers in the President of the United States. It provided the constitutional framework under which the territory has been governed ever since.

1930The US Congress sent a committee to investigate the territory's status 96 years ago

Congress despatched an investigating committee led by Americans who had taken part in the overthrow of the Kingdom of Hawaii. The inquiry followed Mau agitation and reflected unresolved questions about American Samoa's political future.

1938The US Congress gave American Samoa special exemptions in the Fair Labor Standards Act 88 years ago

The Act contained special wage provisions for American Samoa from its inception, citing the territory's limited economy. These exemptions shaped the territorial labour market and the viability of its tuna canning industry for decades.

1941–45US Marines and Samoan recruits turned the territory into a wartime military base 85 years ago

During the Second World War Marines stationed in Samoa outnumbered the local population and exerted a large cultural influence, while Samoan men from the age of fourteen received combat training. Samoans served as combatants, medical and code personnel and ship repairmen, beginning the territory's enduring tradition of high military enlistment.

January 1942A Japanese submarine shelled Tutuila from off Fagasa Bay 84 years ago

At 2:26 a.m. on 13 January 1942 a submarine surfaced between Southworth Point and Fagasa Bay and fired about fifteen shells from its deck gun. The attack brought the Second World War directly to the territory and underlined its strategic exposure.

1949Samoan chiefs led by Tuiasosopo Mariota defeated Organic Act 4500 and won a territorial legislature 77 years ago

An Interior Department-sponsored bill to incorporate American Samoa was introduced in Congress and defeated chiefly through the efforts of Samoan chiefs. Their campaign led instead to the creation of the American Samoa Fono, the territorial legislature meeting at Fagatogo, entrenching local self-rule while preserving unincorporated status.

1950The Department of the Interior took over administration of American Samoa from the Navy 76 years ago

Civil administration of the territory passed from naval to Interior Department control. The transfer ended half a century of direct naval government and began the modern civil administration.

1951President Harry Truman delegated territorial authority by Executive Order 10264 75 years ago

Truman transferred the presidential powers over American Samoa vested by the Ratification Act of 1929 to the Secretary of the Interior. This established the Interior Department as the territory's supervising federal authority.

1956Peter Tali Coleman replaced the naval appointee as the first locally chosen governor 70 years ago

By 1956 the US Navy-appointed governor had been succeeded by Coleman, a Samoan. His accession marked the beginning of indigenous leadership of the territorial executive.

Recent Developments

2022American Samoa formally designated Samoan and English as official languages 4 years ago

The two languages were designated official for the territory, restating the recognition first made in 1999. The measure entrenches the position of the Samoan language alongside English in public life.

July 2021The Legislature of American Samoa unanimously passed a resolution opposing birthright citizenship 5 years ago

On 20 July 2021 the Fono voted unanimously in support of the Tenth Circuit's reversal. The resolution confirmed that resistance to further integration into the US system, evident since the Deeds of Cession, is locally driven.

December 2019The Tenth Circuit Court of Appeals reversed a ruling granting birthright citizenship to American Samoans 7 years ago

District Judge Clark Waddoups struck down 8 U.S.C. § 1408(1) as facially unconstitutional, holding that people born in American Samoa are US citizens under the Citizenship Clause, but the Tenth Circuit reversed and upheld the statute. The outcome preserved the territory's distinctive national-but-not-citizen status.

2012American Samoans in Tuaua v. United States sued for birthright US citizenship 14 years ago

A group of American Samoans brought suit seeking recognition that persons born in the territory are US citizens under the Fourteenth Amendment. The litigation opened a long constitutional contest over the status of the territory's people, who remain US nationals rather than citizens.

2010Voters of American Samoa rejected constitutional amendments on legislative eligibility 16 years ago

A package of territorial constitutional amendments was defeated at the polls, including a provision restricting legislative service by US citizens to those of Samoan ancestry. The vote reflected continuing caution about altering the territory's settled political arrangements.

September 2009An 8.1 magnitude earthquake triggered a tsunami that killed more than 170 people 17 years ago

The largest earthquake of 2009 struck 120 miles off American Samoa at a depth of 11.2 miles on 28 September. The resulting tsunami killed over 170 people across the Samoa Islands and Tonga.

2009Samoa Packing (Chicken of the Sea) closed its tuna cannery, laying off 2,041 workers 17 years ago

The plant shut citing minimum wage increases and, chiefly, rising foreign competition. The closure removed a pillar of the private economy; StarKist began laying off up to 800 workers from August 2010 for similar reasons, leaving a single cannery.

2007The US Congress passed the Fair Minimum Wage Act of 2007 19 years ago

The Act began raising the territorial minimum wage by 50 cents an hour annually towards the federal rate of $7.25. The change was highlighted in Congress at the request of delegate Eni Faleomavaega and had severe consequences for the canning industry.

2001–2003The United States failed to remove the territory from the UN decolonization list 25 years ago

Washington twice argued unsuccessfully that American Samoa should not be considered a colony. The territory remains on the United Nations list of non-self-governing territories, a listing disputed by its own government officials.

August 1999The United Nations granted American Samoa observer seat status 27 years ago

The observer seat was granted on 13 August 1999. Six days later the territory officially recognised both Samoan and English as its official languages, a designation reaffirmed in 2022.

1997American Samoa hosted the 1997 South Pacific Mini Games 29 years ago

The bid to host 23 participating countries was approved in May 1993, with groundbreaking in January 1994 and construction of 1,500-seat stands. Around 2,000 athletes, coaches and sponsors from 19 countries competed in 11 sports, and American Samoa fielded 248 athletes in the biggest international event ever staged in the territory.

1992The American Samoa Government banned hunting of fruit bats and pigeons 34 years ago

Hunting bans were imposed to allow bat and pigeon populations to recover. The Samoa flying fox population held stable at about 900 on Tutuila and 100 in the Manuʻa Islands between 1995 and 2000, though scientists still counted fewer than 5,500 Pacific flying foxes by 2000.

November 1988President Ronald Reagan signed the bill creating the National Park of American Samoa 38 years ago

Reagan signed the legislation on 1 November 1988, after the National Park Service began establishing the park in July 1987 and an initial appropriation of $400,000 in 1989. Governor Peter Tali Coleman and Interior Secretary Manuel Lujan signed the formalising leases on 19 September 1991, creating the fiftieth US national park.

1987American Samoa became the 167th member of the International Olympic Committee 39 years ago

Membership gave the territory its own Olympic representation. It was an early instance of American Samoa acting in its own name in international bodies.

1984Congressman Fofō Iosefa Fiti Sunia introduced a bill bringing the territory into the Federal Fish and Wildlife Restoration Act 42 years ago

The measure was urged by Paul Cox, High Chief Nafanua of Falealupo and the Bat Preservers Association. It connected American Samoa to federal wildlife conservation funding and frameworks.

1983The courts ruled the territory's citizenship-based taxation unconstitutional 43 years ago

American Samoa's incorporation of the US tax code led it to tax on the basis of citizenship, a practice struck down in 1983. The territory continues to tax worldwide income of residents and locally generated income of non-residents under modified rules based on the 2000 US code.

1982Pope John Paul II created the Diocese of Samoa-Pago Pago 44 years ago

The diocese was erected through the bull Studiose quidem as a suffragan see of the Archdiocese of Samoa-Apia. It gave the territory's Catholics, served by at least eighteen churches and twenty-nine parishes, their own ecclesiastical structure.

1980The territorial legislature established a Department of Parks and Recreation and Parks Commission 46 years ago

The department and commission were created by law, and Governor Peter Tali Coleman appointed Fuga Tolani Teleso as director in 1981. The move institutionalised public recreation and conservation administration in the territory.

1978The US Congress created the office of delegate to the House of Representatives 48 years ago

The territory gained a non-voting delegate's seat, first filled in 1981 by Democrat Fofō Iosefa Fiti Sunia. Only three people have held it, with Eni Faleomavaega serving 1989–2015 and Aumua Amata Radewagen from 2015, giving American Samoa a permanent voice in Washington.

January 1974Pan Am Flight 806 crashed at Pago Pago International Airport, killing 86 52 years ago

The flight from Auckland crashed on approach at 10:41 pm on 30 January 1974 with 91 passengers aboard; 86 died, including the captain. It remains the territory's worst aviation disaster and was revisited in a documentary filmed locally in 2014.

1972The United States designated American Samoa's seven National Natural Landmarks 54 years ago

Seven sites in the territory were given National Natural Landmark status. The designation was an early formal recognition of the islands' distinctive natural heritage.

November 1970Pope Paul VI made a papal visit to American Samoa 56 years ago

The pope was received in a brief but lavish greeting during a stopover. The visit reflected the depth of Christian, and specifically Catholic, attachment in the territory.

1970American Samoa Community College was founded to provide post-secondary education 56 years ago

The college was established as the territory's institution of higher education. It remains the principal provider of post-secondary education on the islands.

1969–1972American Samoa and Pago Pago International Airport served as the recovery gateway for Apollo missions 57 years ago

Astronaut crews of Apollo 10, 12, 13, 14 and 17 were retrieved a few hundred miles from Pago Pago and flown by helicopter to the airport before transfer to Honolulu aboard C-141 Starlifters. The role gave the territory a prominent place in the American space programme.

1967Interior Secretary Stewart Udall promulgated the Revised Constitution of American Samoa 59 years ago

Ratified in 1966 and promulgated on 2 June 1967, the constitution took effect on 1 July 1967 and made the territory self-governing with separate executive, legislative and judicial branches. Although American Samoa remains technically unorganised, the constitution has been the basis of domestic government ever since.

1964Governor Rex Lee introduced the territory's public television system 62 years ago

Educational television was launched with some 6,000 programmes produced annually at its peak. By 1981 the system had contracted to a single series of 40-minute English-language lessons.

June 1963Paramount Chief Tuli Leʻiato was installed as the first Secretary of Samoan Affairs 63 years ago

The Fagaʻitua paramount chief was sworn in on 21 June 1963 in the newly created post. The office institutionalised traditional Samoan leadership within the territorial government.

1961The matai and naval governor opened the territory's first high school at Utulei 65 years ago

Pressure from the matai on the naval governor converted the old Marine barracks at Utulei into American Samoa's only high school. With a median age of fifteen, demand grew rapidly: three more high schools opened by 1968 and six public and private high schools served 2,800 students by 1979.

1960sThe territorial government began efforts to develop a tourism industry 66 years ago

From the mid-1960s deliberate steps were taken to build tourism in American Samoa. It marked an attempt to diversify an economy dominated by government employment and tuna canning.

Economy - overview

American Samoa has a traditional Polynesian economy in which more than 90% of the land is communally owned. Economic activity is strongly linked to the US with which American Samoa conducts most of its commerce. Tuna fishing and tuna processing plants are the backbone of the private sector with canned tuna the primary export. The two tuna canneries account for 80% of employment. In late September 2009, an earthquake and the resulting tsunami devastated American Samoa and nearby Samoa, disrupting transportation and power generation, and resulting in about 200 deaths. The US Federal Emergency Management Agency is overseeing a relief program of nearly $25 million. Transfers from the US Government add substantially to American Samoa's economic well being. Attempts by the government to develop a larger and broader economy are restrained by Samoa's remote location, its limited transportation, and its devastating hurricanes. Tourism is a promising developing sector.
