At the western end of the Samoan Island chain lies Savai'i. Stretching over 1,682 sq km (649 sq mi), Savai'i is one of the largest landmasses in Polynesia. The mountainous island is a shield volcano that reaches its highest altitude, 1,858 m (6,095 ft), near the center of the island. The region's tropical, humid climate sustains vegetation that carpets much of the island.
A jagged line of small, round volcanic craters extends east-west across the island (top of image). South of this uneven line, two deep, parallel valleys extend toward the south. The semicircular contours of the valleys suggest that they might be the remains of an ancient caldera or collapsed magma chamber that was modified by the later eruption of additional lava.
With the exception of a few brown crater rims, and a coastal settlement along the image's left edge, the landscape appears in varying shades of green. Dense rainforests cover the island's rugged interior, and thick vegetation also thrives along the coastal plains.
Savai'i has remained volcanically active into historical times, with two eruptions occurring in the early 20th century. The eruptions sent big lava flows to the island's northern coast, destroying several villages. Photo courtesy of NASA.
The topography of Savai’i (background) and Upolu (forefront), the two large islands of the Independent State of Samoa, is well shown in this color-coded perspective view from a NASA Shuttle Radar Topography Mission. Image courtesy of NASA.

This is the population pyramid for Samoa. A population pyramid illustrates the age and sex structure of a country's population and may provide insights about political and social stability, as well as economic development. The population is distributed along the horizontal axis, with males shown on the left and females on the right. The male and female populations are broken down into 5-year age groups represented as horizontal bars along the vertical axis, with the youngest age groups at the bottom and the oldest at the top. The shape of the population pyramid gradually evolves over time based on fertility, mortality, and international migration trends.

Background
The first Austronesian settlers arrived in Samoa around 1000 B.C., and early Samoans traded and intermarried with Fijian and Tongan nobility. The fa’amatai system of titles and nobility developed, which dominates Samoan politics to this day; all but two seats in the legislature are reserved for matai, or heads of families. Dutch explorer Jacob ROGGEVEEN was the first European to spot the islands in 1722. Christian missionaries arrived in the 1830s, converting most of the population. In the 1850s, Apia became a center for Pacific trading and hosted an American commercial agent and British and German consuls. In 1892, American traders convinced the Samoan king to align his country’s date with the US, moving to the east of the International Date Line.
Following the death of the Samoan king in 1841, rival families competed for his titles, devolving into civil war in 1886 with factions getting support from either Germany, the UK, or the US. All three countries sent warships to Apia in 1889, presaging a larger war, but a cyclone destroyed the ships and Malietoa LAUPEPA was installed as king. Upon LAUPEPA’s death in 1898, a second civil war over succession broke out. The war ended in 1899 and the Western powers abolished the monarchy, giving the western Samoan islands to Germany and the eastern Samoan islands to the US. The UK abandoned claims in Samoa and received former German territory in the Solomon Islands.
The Mau, a non-violent popular movement to advocate for Samoan independence, formed in 1908. New Zealand annexed Samoa in 1914 after the outbreak of World War I. Opposition to New Zealand’s rule quickly grew. In 1918, a New Zealand ship introduced the Spanish flu, infecting 90% of the population and killing more than 20%. In 1929, New Zealand police shot into a crowd of peaceful protestors, killing 11, in an event known as Black Sunday. In 1962, Samoa became the first Polynesian nation to reestablish its independence as Western Samoa but dropped the “Western” from its name in 1997. The Human Rights Protection Party dominated politics from 1982 until current Prime Minister FIAME Naomi Mata'afa's Fa'atuatua i le Atua Samoa ua Tasi or FAST party gained a majority in elections in 2021.
In the late 2000s, Samoa began making efforts to align more closely with Australia and New Zealand. In 2009, Samoa changed its driving orientation to the left side of the road, in line with other Commonwealth countries. In 2011, Samoa jumped forward one day - skipping December 30 - by moving to the west side of the International Date Line so that it was one hour ahead of New Zealand and three hours ahead of the east coast of Australia, rather than 23 and 21 hours behind, respectively.

Telecommunication systems
general assessment: Samoa was one of the first Pacific Island countries to establish a regulatory infrastructure and to liberalize its telecom market; the advent of competition in the mobile market saw prices fall by around 50% and network coverage increase to more than 90% of the population; Samoa also boasts one of the highest rates of mobile phone coverage in the Pacific region; the growth of fixed-line internet has been impeded by factors including the high costs for bandwidth, under investment in fixed-line infrastructure; Samoa’s telecoms sector has been inhibited by a lack of international connectivity; Samoa has had access to the Samoa-America-Samoa (SAS) cable laid in 2009, this cable has insufficient capacity to meet the country’s future bandwidth needs; this issue was addressed with two new submarine cables that became available in 2018 and 2019; combined with the Samoa National Broadband Highway (SNBH), have improved internet data rates and reliability, and have helped to reduce the high costs previously associated with internet access in Samoa; in April 2022, the Samoan government announced its decision to take over control of the Samoa Submarine Cable Company, looking to the cable to generate additional revenue for the state (2022)
domestic: fixed-line is 3 per 100 and mobile-cellular teledensity 32 telephones per 100 persons (2021)
international: country code - 685; landing points for the Tui-Samo, Manatua, SAS, and Southern Cross NEXT submarine cables providing connectivity to Samoa, Fiji, Wallis & Futuna, Cook Islands, Niue, French Polynesia, American Samoa, Australia, New Zealand, Kiribati, Los Angeles (US), and Tokelau; satellite earth station - 1 Intelsat (Pacific Ocean) (2019)

Samoa has a "shiprider" agreement with the US, which allows local maritime law enforcement officers to embark on US Coast Guard (USCG) and US Navy (USN) vessels, including to board and search vessels suspected of violating laws or regulations within Somoa's designated exclusive economic zone (EEZ) or on the high seas; "shiprider" agreements also enable USCG personnel and USN vessels with embarked USCG law enforcement personnel to work with host nations to protect critical regional resources (2023)
Country name
conventional long form: Independent State of Samoa
conventional short form: Samoa
local long form: Malo Sa'oloto Tuto'atasi o Samoa
local short form: Samoa
former: Western Samoa
etymology: the meaning of Samoa is disputed; some modern explanations are that the "sa" connotes "sacred" and "moa" indicates "center," so the name can mean "Holy Center"; alternatively, some assertions state that it can mean "place of the sacred moa bird" of Polynesian mythology; the name, however, may go back to Proto-Polynesian (PPn) times (before 1000 B.C.); a plausible PPn reconstruction has the first syllable as "sa'a" meaning "tribe or people" and "moa" meaning "deep sea or ocean" to convey the meaning "people of the deep sea"
