Kiribati

Kiribati is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kiribati rather than just read about it. In short: Kiribati, officially the Republic of Kiribati, is an archipelagic country spanning the Micronesia and Polynesia sub-regions of Oceania in the central Pacific Ocean. The state comprises 32 atolls and other islands and one remote raised coral island, Banaba.

Key takeaways

  • Kiribati belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Kiribati to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Kiribati from memory before moving on to harder problems.

Reference excerpt

Kiribati, officially the Republic of Kiribati, is an archipelagic country spanning the Micronesia and Polynesia sub-regions of Oceania in the central Pacific Ocean. The state comprises 32 atolls and other islands and one remote raised coral island, Banaba. Its total land area is 811 km2 (313 sq mi) dispersed over 3,441,810 km2 (1,328,890 sq mi) of ocean. The spread of the country's islands, from Banaba in the west to Kiritimati in the east straddles the equator and the 180th meridian. The International Date Line goes around Kiribati and swings far to the east, almost reaching 150°W. This brings Kiribati's easternmost islands, the southern Line Islands south of Hawaii, into the same day as the Gilbert Islands and places them in the most advanced time zone on Earth: UTC+14. The permanent population of Kiribati is just over 138,000 as of the 2026 census, and more than half live on Tarawa. There is also a significant number of I‑Kiribati forming a diaspora, the largest of which still growing via emigration is probably in New Zealand; historically, diasporic communities were created through over-population resettlement in the Solomon Islands on Ghizo and Wagina, and through intermarriage in the United Kingdom and United States. Another country with growing diasporic communities born of recent labour immigration is Australia. The I‑Kiribati are a Micronesian people that speaks the Gilbertese language. The Gilberts were politically autonomous of each other, more or less, and anywhere else, until annexed as a protectorate in 1892 by the British; they had no political connection then with the Phoenix or Line islands. This annexation was ended in 1979, when Kiribati gained its independence from the United Kingdom, becoming a sovereign state in 1979. The sovereign state included the Gilberts, the Phoenix and Line islands and Banaba. The capital, Tarawa, now the most populated area, consists of a number of islets, connected by a series of causeways. These comprise about half the area of Tarawa Atoll. Prior to its independence the country exported phosphate, but the mine, on Banaba, is virtually exhausted and no longer viable. The descendants of the Banabans mostly live in exile on Rabi in Fiji but are represented in the Kiribati Parliament. Fisheries, subsistence agriculture and the export of copra drive much of the economy, particularly on outer islands away from Tarawa. Kiribati is one of the least developed countries in the world and its government is highly dependent on fishing licence fees from foreign fleets and international capital aid to finance infrastructure and other projects. Many families rely on remittances from circular labour migrants (seafarers, agricultural workers, urban service workers). They also work for the government or for private business and non-business organisations, or run trade stores and small private cooperative-like businesses. The government now pays benefits to the unemployed on Tarawa and to the elderly. Kiribati is a member of the Pacific Community, Commonwealth of Nations, the International Monetary Fund, the World Bank, and the Organisation of African, Caribbean and Pacific States, and became a full member of the United Nations in 1999. As an atoll (and other low-lying island) nation, Kiribati is acutely vulnerable to sea-level rise and climate change. This is in addition to threats from tsunamis since time-immemorial. Addressing climate change has been a central part of its international policy, as a member of the Alliance of Small Island States. In Kiribati, climate change and extreme weather events are predicted to become more frequent. Additionally, existing socio-economic and environmental pressures are intensifying.

Etymology and pronunciation The name is pronounced KIRR-i-bass, as -ti in the Gilbertese language represents an [s] sound. Similarly, the name of its people, the I-Kiribati, is pronounced ee-KIRR-i-bass.

The name Kiribati was adopted upon the country's independence in 1979. It is the Gilbertese rendition of Gilberts, the plural of the English name of the nation's main archipelago, the Gilbert Islands. It was named îles Gilbert (French for 'Gilbert Islands') in about 1820 by Russian admiral Adam von Krusenstern and French captain Louis Duperrey, after the British captain Thomas Gilbert. Gilbert and captain John Marshall sighted some of the islands in 1788, while charting the "outer passage" route from Port Jackson to Canton. Both von Krusenstern's and Duperrey's maps, published in 1824, were written in French. In French, the Northern Islands were until then called îles Mulgrave and Byron's Island was not part of them. In English, the archipelago, particularly the southern part, was often referred to as the Kingsmills in the 19th century, although the name Gilbert Islands was used increasingly, including for the purposes of the Western Pacific High Commission in the Western Pacific Order-in-Council of 1877 and Pacific Order-in-Council of 1893. The name Gilbert, already in the name of the British protectorate since 1892, was incorporated into the name of the entire Gilbert and Ellice Islands Colony (GEIC) from 1916 and was retained after the Ellice Islands became the separate country of Tuvalu in 1976. The spelling of Gilberts in the Gilbertese language as Kiribati may be found in books in Gilbertese prepared by missionaries, but with the meaning of Gilbertese (demonym and language) (see e.g., Hawaiian Board of Missionaries, 1895). The first mention as a dictionary entry of the word Kiribati as the native name of the country was written down in 1952 by Ernest Sabatier in his comprehensive Dictionnaire gilbertin–français. The indigenous name often suggested for the Gilbert Islands proper is Tungaru (see e.g., Ernest Sabatier, 1952–1953, or Arthur Grimble, 1989). The rendition Kiribati for Gilberts was chosen as the official name of the new independent state by the chief minister, Sir Ieremia Tabai and his cabinet, on such grounds that it was modern, and to indicate the inclusion of islands (e.g., the Phoenix and Line Islands), beyond the Tungaru (i.e., Gilbert) chain.

Worked examples

Example 1 — a first encounter with Kiribati

Start with the simplest possible case. Write down what Kiribati claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kiribati before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kiribati ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kiribati

In research
Kiribati appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Kiribati in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Kiribati is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1979 establishments in Oceania, British Western Pacific Territories, Countries and territories where English is an official language, so understanding it makes those chapters shorter.
In everyday life
Look for Kiribati outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
