NASA
–
President Dwight D. Eisenhower established NASA in 1958 with a distinctly civilian orientation encouraging peaceful applications in space science. The National Aeronautics and Space Act was passed on July 29,1958, disestablishing NASAs predecessor, the new agency became operational on October 1,1958. Since that time, most US space exploration efforts have led by NASA, including the Apollo Moon landing missions, the Skylab space station. Currently, NASA is supporting the International Space Station and is overseeing the development of the Orion Multi-Purpose Crew Vehicle, the agency is also responsible for the Launch Services Program which provides oversight of launch operations and countdown management for unmanned NASA launches. NASA shares data with various national and international such as from the Greenhouse Gases Observing Satellite. Since 2011, NASA has been criticized for low cost efficiency, from 1946, the National Advisory Committee for Aeronautics had been experimenting with rocket planes such as the supersonic Bell X-1. In the early 1950s, there was challenge to launch a satellite for the International Geophysical Year. An effort for this was the American Project Vanguard, after the Soviet launch of the worlds first artificial satellite on October 4,1957, the attention of the United States turned toward its own fledgling space efforts. This led to an agreement that a new federal agency based on NACA was needed to conduct all non-military activity in space. The Advanced Research Projects Agency was created in February 1958 to develop technology for military application. On July 29,1958, Eisenhower signed the National Aeronautics and Space Act, a NASA seal was approved by President Eisenhower in 1959. Elements of the Army Ballistic Missile Agency and the United States Naval Research Laboratory were incorporated into NASA, earlier research efforts within the US Air Force and many of ARPAs early space programs were also transferred to NASA. In December 1958, NASA gained control of the Jet Propulsion Laboratory, NASA has conducted many manned and unmanned spaceflight programs throughout its history. Some missions include both manned and unmanned aspects, such as the Galileo probe, which was deployed by astronauts in Earth orbit before being sent unmanned to Jupiter, the experimental rocket-powered aircraft programs started by NACA were extended by NASA as support for manned spaceflight. This was followed by a space capsule program, and in turn by a two-man capsule program. This goal was met in 1969 by the Apollo program, however, reduction of the perceived threat and changing political priorities almost immediately caused the termination of most of these plans. NASA turned its attention to an Apollo-derived temporary space laboratory, to date, NASA has launched a total of 166 manned space missions on rockets, and thirteen X-15 rocket flights above the USAF definition of spaceflight altitude,260,000 feet. The X-15 was an NACA experimental rocket-powered hypersonic research aircraft, developed in conjunction with the US Air Force, the design featured a slender fuselage with fairings along the side containing fuel and early computerized control systems

Pacific Ocean
–
The Pacific Ocean is the largest and deepest of the Earths oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bounded by Asia and Australia in the west, the Mariana Trench in the western North Pacific is the deepest point in the world, reaching a depth of 10,911 metres. Both the center of the Water Hemisphere and the Western Hemisphere are in the Pacific Ocean, the oceans current name was coined by Portuguese explorer Ferdinand Magellan during the Spanish circumnavigation of the world in 1521, as he encountered favourable winds on reaching the ocean. He called it Mar Pacífico, which in both Portuguese and Spanish means peaceful sea, important human migrations occurred in the Pacific in prehistoric times. Long-distance trade developed all along the coast from Mozambique to Japan, trade, and therefore knowledge, extended to the Indonesian islands but apparently not Australia. By at least 878 when there was a significant Islamic settlement in Canton much of trade was controlled by Arabs or Muslims. In 219 BC Xu Fu sailed out into the Pacific searching for the elixir of immortality, from 1404 to 1433 Zheng He led expeditions into the Indian Ocean. The east side of the ocean was discovered by Spanish explorer Vasco Núñez de Balboa in 1513 after his expedition crossed the Isthmus of Panama and he named it Mar del Sur because the ocean was to the south of the coast of the isthmus where he first observed the Pacific. Later, Portuguese explorer Ferdinand Magellan sailed the Pacific East to West on a Castilian expedition of world circumnavigation starting in 1519, Magellan called the ocean Pacífico because, after sailing through the stormy seas off Cape Horn, the expedition found calm waters. The ocean was often called the Sea of Magellan in his honor until the eighteenth century, sailing around and east of the Moluccas, between 1525 and 1527, Portuguese expeditions discovered the Caroline Islands, the Aru Islands, and Papua New Guinea. In 1542–43 the Portuguese also reached Japan, in 1564, five Spanish ships consisting of 379 explorers crossed the ocean from Mexico led by Miguel López de Legazpi and sailed to the Philippines and Mariana Islands. The Manila galleons operated for two and a half centuries linking Manila and Acapulco, in one of the longest trade routes in history, Spanish expeditions also discovered Tuvalu, the Marquesas, the Cook Islands, the Solomon Islands, and the Admiralty Islands in the South Pacific. In the 16th and 17th century Spain considered the Pacific Ocean a Mare clausum—a sea closed to other naval powers, as the only known entrance from the Atlantic the Strait of Magellan was at times patrolled by fleets sent to prevent entrance of non-Spanish ships. On the western end of the Pacific Ocean the Dutch threatened the Spanish Philippines, Spain also sent expeditions to the Pacific Northwest reaching Vancouver Island in southern Canada, and Alaska. The French explored and settled Polynesia, and the British made three voyages with James Cook to the South Pacific and Australia, Hawaii, and the North American Pacific Northwest, one of the earliest voyages of scientific exploration was organized by Spain in the Malaspina Expedition of 1789–1794. It sailed vast areas of the Pacific, from Cape Horn to Alaska, Guam and the Philippines, New Zealand, Australia, and the South Pacific. Growing imperialism during the 19th century resulted in the occupation of much of Oceania by other European powers, and later, Japan, in Oceania, France got a leading position as imperial power after making Tahiti and New Caledonia protectorates in 1842 and 1853 respectively. After navy visits to Easter Island in 1875 and 1887, Chilean navy officer Policarpo Toro managed to negotiate an incorporation of the island into Chile with native Rapanui in 1888, by occupying Easter Island, Chile joined the imperial nations

Tuamotus
–
Its major islands are Anaa, Fakarava, Hao and Makemo. The Tuamotu islands were settled by Polynesians, so Tuamotuans share a common culture. French Polynesia is an island group designated as an overseas country of France. The Tuamotus combine with the Gambier Islands to form the Îles Tuamotu-Gambier which is one of the five divisions of French Polynesia. The Tuamotus are grouped into sixteen communes, Anaa, Arutua, Fakarava, Fangatau, Hao, Hikueru, Makemo, Manihi, Napuka, Nukutavake, Puka Puka, Rangiroa, Reao, Takaroa, Tatakoto, and Tureia. The communes on Tuamotu are part of two different electoral districts represented in the Assembly of French Polynesia, the other five communes in western Tuamotu – Arutua, Fakarava, Manihi, Rangiroa, and Takaroa – form the Îles Tuamotu Ouest electoral district. At the 2007 census, the Tuamotus had a population of 18,317 inhabitants, of these,769 inhabitants live in a 215-nautical-mile radius around Mururoa and Fangataufa, the sites of former French nuclear tests. The common language spoken in the Tuamotus is Tuamotuan, except in Puka-Puka which uses the Marquesan language, the islands economy is predominantly composed of subsistence agriculture. The most important sources of income are the cultivation of black pearls. Tourism-related income remains meager, especially by comparison to the industry of the neighboring Society Islands. A modest tourism infrastructure is found on the atolls of Rangiroa, despite the vast spread of the archipelago, it covers a total land area of only about 885 km2. The climate is tropical, without pronounced seasons. The annual average temperature is a relatively continuous 26 °C, water sources such as lakes or rivers are absent, leaving catchments of rain as the only source of fresh water. The annual average rainfall is 1400 mm, rainfall is not markedly different throughout the year, although it is lowest during the months of September and November. Geological stability of the archipelago is high, as it was created by the weakly active Easter Fracture Zone, no volcanic eruptions have been recorded historically. The sparse soil of the coral islands does not permit a diverse vegetation, the coconut palm, which forms the basis for copra production, is of special economic importance. On a few islands, vanilla is also cultivated, agriculture is generally otherwise limited to simple subsistence. Fruit and vegetable staples include yams, taro, and breadfruit, pandanus leaves are traditionally woven together as roof thatch, as well as for other items, such as mats and hats

French Polynesia
–
It is composed of 118 geographically dispersed islands and atolls stretching over an expanse of more than 2,000 kilometres in the South Pacific Ocean. Its total land area is 4,167 square kilometres, among its 118 islands and atolls,67 are inhabited. Tahiti, which is located within the Society Islands, is the most populous island and it has more than 68% of the population of the islands in 2012. Although not a part of its territory, Clipperton Island was administered from French Polynesia until 2007. Following the Great Polynesian Migration, European explorers visited the islands of French Polynesia on several occasions, traders and whaling ships also visited. In 1842, the French took over the islands and established a French protectorate they called Etablissements des français en Océanie, in 1946, the EFOs became an overseas territory under the constitution of the French Fourth Republic, and Polynesians were granted the right to vote through citizenship. In 1957, the EFOs were renamed French Polynesia, French Polynesia as we know it today was one of the last places on Earth to be settled by humans. Scientists believe the Great Polynesian Migration happened around 1500 BC as Austronesian people went on a journey using celestial navigation to find islands in the South Pacific Ocean, the first islands of French Polynesia to be settled were the Marquesas Islands in about 200 BC. The Polynesians later ventured southwest and discovered the Society Islands around AD300, European encounters began in 1521 when Portuguese explorer Ferdinand Magellan, sailing at the service of the Spanish Crown, sighted Puka-Puka in the Tuāmotu-Gambier Archipelago. Over a century later, British explorer Samuel Wallis visited Tahiti in 1767, French explorer Louis Antoine de Bougainville also visited Tahiti in 1768, while British explorer James Cook arrived in 1769. A short-lived Spanish settlement was created in 1774, and for a time some maps bore the name Isla de Amat after Viceroy Amat, in 1772, Dutchman Jakob Roggeveen came across Bora Bora in the Society Islands. Christian missions began with Spanish priests who stayed in Tahiti for a year, protestants from the London Missionary Society settled permanently in Polynesia in 1797. King Pōmare II of Tahiti was forced to flee to Moorea in 1803, he, French Catholic missionaries arrived on Tahiti in 1834, their expulsion in 1836 caused France to send a gunboat in 1838. In 1842, Tahiti and Tahuata were declared a French protectorate, the capital of Papeetē was founded in 1843. In 1880, France annexed Tahiti, changing the status from that of a protectorate to that of a colony, the island groups were not officially united until the establishment of the French protectorate in 1889. In the 1880s, France claimed the Tuamotu Archipelago, which belonged to the Pōmare Dynasty. Having declared a protectorate over Tahuata in 1842, the French regarded the entire Marquesas Islands as French, in 1885, France appointed a governor and established a general council, thus giving it the proper administration for a colony. The islands of Rimatara and Rūrutu unsuccessfully lobbied for British protection in 1888, postage stamps were first issued in the colony in 1892

Gambier Islands
–
Because of their proximity, the Acteon Group, and the nearby atolls of Maria Est, Morane, Marutea Sud and Temoe, all permanently uninhabited, are sometimes included among the Gambiers. The commune of Gambier is made up of the Gambier Islands, the uninhabited Acteon Group to the northwest, and this group of islands and atolls covers an area of 35 km². Although these archipelagos are administered as a municipality, the main village is Rikitea. Temoe atoll, one island and a dozen of motus separated by passes over the corall reef. Acteon Group made of four atolls Tenararo, Vahanga, Tenarunga, apart from the above groups, it also includes the three isolated atolls of Marutea Sud, Maria Est, and Morane. The Gambier Islands, together with the islands in the part of the Tuamotus, form Îles Gambier et Tuamotu Est. Together with the Tuamotus, the Gambier Islands form Îles Tuamotu-Gambier, the Gambier Islands proper have an enclosing coral reef which is broken by only three passages to the open sea. Besides Mangareva, the notable high islands of the group are Akamaru, Angakauitai, Aukena, Kamaka, Kouaku, Makapu, Makaroa, Manui, Mekiro. These are primarily of volcanic origin, a number of others are actually coral islands, hence of secondary volcanic origin, including Papuri, Puaumu, Totengengie and the Tokorua group. The islands proper are located at 23°09′S 134°58′W and are approximately 31 km² in area, the total population in 2007 was 1,641. The primary town is Rikitea, located on Mangareva, as is the highest point in the Gambiers, Mt. Duff, the more distant atolls of the Gambiers in the broad sense are all uninhabited. However, excessive logging by the islanders resulted in almost complete deforestation on Mangareva, with results for the islands environment. The folklore of the records a slide into civil war and even cannibalism as trade links with the outside world broke down. Today, the islands can support a population of only a few hundred, in 1834, the French Picpus priests Honoré Laval and François Caret with their assistant Columba Murphy founded a Roman Catholic mission in the Gambiers. After their success here, they moved to Tahiti in 1836, Mangareva along with its dependencies in the Gambier Islands were ruled by a line of kings and later regents that ruled until the French formally annexed the islands in 1881. A French protectorate was requested on 16 February 1844 by King Maputeoa but was never ratified by the French government, on 4 February 1870, Prince Regent Arone Teikatoara and the Mangarevan government formally withdrew the protectorate request and asked the French to not intervene in the kingdoms affairs. The Gambier Islands were finally annexed on 21 February 1881 under Prince Regent Bernardo Putairi, the Gambiers served as a logistical staging base for French nuclear testing activity in Mururoa, approximately 400 kilometers away. During this time, the French military dragged a chain through some of the reef beds to cut a wider and deeper channel for deep draft vessels

Atoll
–
An atoll, sometimes called a coral atoll, is a ring-shaped coral reef including a coral rim that encircles a lagoon partially or completely. There may be coral islands/cays on the rim, the coral of the atoll often sits atop the rim of an extinct seamount or volcano which has eroded or subsided partially beneath the water. The lagoon forms over the crater or caldera while the higher rim remains above water or at shallow depths that permit the coral to grow. For the atoll to persist, continued erosion or subsidence must be at a slow enough to permit reef growth upwards and outwards to replace the lost height. The word atoll comes from the Dhivehi word atholhu, meaning an administrative subdivision, the distribution of atolls around the globe is instructive, most of the worlds atolls are in the Pacific Ocean and Indian Ocean. The Atlantic Ocean has no large groups of atolls, other than eight atolls east of Nicaragua that belong to the Colombian department of San Andres and Providencia in the Caribbean. Reef-building corals will thrive only in tropical and subtropical waters of oceans and seas. The northernmost atoll of the world is Kure Atoll at 28°24 N, the southernmost atolls of the world are Elizabeth Reef at 29°58 S, and nearby Middleton Reef at 29°29 S, in the Tasman Sea, both of which are part of the Coral Sea Islands Territory. The next southerly atoll is Ducie Island in the Pitcairn Islands Group, at this latitude coral reefs would not develop without the warming waters of the Gulf Stream. However, Bermuda is termed a pseudo-atoll because its general form, while there is no atoll directly on the equator, the closest atoll to the Equator is Aranuka of Kiribati, with its southern tip just 12 km north of the equator. In most cases, the area of an atoll is very small in comparison to the total area. Atoll islands are low lying, with their elevations less than 5 meters, measured by total area, Lifou is the largest raised coral atoll of the world, followed by Rennell Island. More sources however list as the largest atoll in the world in terms of land area Kiritimati, the remains of an ancient atoll as a hill in a limestone area is called a reef knoll. The second largest atoll by dry land area is Aldabra with 155 km², the largest atoll in terms of island numbers is Huvadhu Atoll in the south of the Maldives with 255 islands. In 1842, Charles Darwin explained the creation of coral atolls in the southern Pacific Ocean based upon observations made during a voyage aboard the HMS Beagle from 1831 to 1836. In time, subsidence carries the old volcano below the ocean surface, at this point, the island has become an atoll. Atolls are the product of the growth of marine organisms. Volcanic islands located beyond the water temperature requirements of hermatypic organisms become seamounts as they subside and are eroded away at the surface

Tahiti
–
Tahiti is the largest island in the Windward group of French Polynesia, this overseas collectivity of the French Republic is sometimes referred to as a French overseas country. The island was formed from volcanic activity and is high and mountainous with surrounding coral reefs, the population is 183,645 inhabitants, making it the most populous island of French Polynesia and accounting for 68.5 percent of its total population. Tahiti is the economic, cultural and political centre of French Polynesia, the capital, Papeete, is located on the northwest coast with the only international airport in the region, Faaā International Airport, situated 5 km from the town centre. Tahiti was originally settled by Polynesians between 300 and 800 CE and they represent about 70 percent of the islands population with the rest made up of Europeans, Chinese and those of mixed heritage. The island was part of the Kingdom of Tahiti until its annexation by France in 1880, when it was proclaimed a colony of France, French is the only official language although the Tahitian language is widely spoken. Tahiti is the highest and largest island in French Polynesia lying close to Moorea island and it is located 4,400 kilometres south of Hawaii,7,900 km from Chile and 5,700 km from Australia. The island is 45 km across at its widest point and covers an area of 1,045 km2, the highest peak is Mont Orohena. Mount Roonui, or Mount Ronui in the southeast rises to 1,332 m, the island consists of two roughly round portions centred on volcanic mountains and connected by a short isthmus named after the small town of Taravao, situated there. The northwestern portion is known as Tahiti Nui, while the much smaller portion is known as Tahiti Iti or Taiarapū. Tahiti Nui is heavily populated along the coast, especially around the capital, the interior of Tahiti Nui is almost entirely uninhabited. Tahiti Iti has remained isolated, as its half is accessible only to those travelling by boat or on foot. The rest of the island is encircled by a road which cuts between the mountains and the sea. A scenic and winding road climbs past dairy farms and citrus groves with panoramic views. Tahitis landscape features lush rainforests and many rivers and waterfalls, including the Papenoo River on the side. November to April is the wet season, the wettest month of which is January with 13.2 in of rain in Papeetē, August is the driest with 1.9 inches. The average temperature ranges between 21 and 31 °C with little seasonal variation, the lowest and highest temperatures recorded in Papeete are 16 and 34 °C, respectively. The first Tahitians arrived from Southeast Asia in about 200 BCE and this hypothesis of an emigration from Southeast Asia is supported by a number of linguistic, biological and archaeological proofs. For example, the languages of Fiji and Polynesia all belong to the same Oceanic sub-group, Fijian-Polynesian, in 1769, for instance, James Cook mentions a great traditional ship in Tahiti that was 33 m long, and could be propelled by sail or paddles

Coconut
–
The coconut tree is a member of the family Arecaceae and the only species of the genus Cocos. The term coconut can refer to the coconut palm or the seed, or the fruit. The spelling cocoanut is a form of the word. The term is derived from the 16th-century Portuguese and Spanish word coco meaning head or skull, coconuts are known for their great versatility, as evidenced by many traditional uses, ranging from food to cosmetics. They form a part of the diets of many people in the tropics and subtropics. Coconuts are distinct from other fruits for their quantity of water. When mature, they can be used as seed nuts or processed to give oil from the kernel, charcoal from the hard shell, the endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, when dried, the coconut flesh is called copra. The oil and milk derived from it are used in cooking and frying, as well as in soaps. The husks and leaves can be used as material to make a variety of products for furnishing and decorating, the coconut also has cultural and religious significance in certain societies, particularly in India, where it is used in Hindu rituals. Cocos nucifera is a palm, growing up to 30 m tall, with pinnate leaves 4–6 m long. Coconuts are generally classified into two types, tall and dwarf. On fertile soil, a coconut palm tree can yield up to 75 fruits per year. Given proper care and growing conditions, coconut palms produce their first fruit in six to ten years, botanically, the coconut fruit is a drupe, not a true nut. Like other fruits, it has three layers, the exocarp, mesocarp, and endocarp, the exocarp and mesocarp make up the husk of the coconuts. Coconuts sold in the shops of nontropical countries often have had the exocarp removed, the mesocarp is composed of a fiber, called coir, which has many traditional and commercial uses. The shell has three germination pores or eyes that are visible on its outside surface once the husk is removed. A full-sized coconut weighs about 1.44 kg and it takes around 6,000 full-grown coconuts to produce a tonne of copra

Cassytha filiformis
–
Cassytha filiformis, common name love-vine, is a species of obligate parasitic vine in the family Lauraceae. Cassytha filiformis is a vine with an orange to pale green stem. Leaves are reduced to scales about 1 mm long, flowers are borne in spikes or sometimes solitary. There are six tepals, each 0. 1-2.0 mm long, fruit is a drupe about 7 mm in diameter.

Amaranthaceae
–
Amaranthaceae is a family of flowering plants known as the amaranth family. It now includes the former goosefoot family Chenopodiaceae, and contains about 165 genera and 2,040 species, making it the most species-rich lineage within the flowering plant order of Caryophyllales. Most of these species are annual or perennial herbs or subshrubs, some are shrubs, many species have stems with thickened nodes. The wood of the stem has a typical anomalous secondary growth. The leaves are alternate, sometimes opposite. The simple leaves are flat or terete, their shape is extremely variable, in some species, the leaves are reduced to minute scales. In most cases, neither basal or terminal aggregations of leaves occur, the flowers are solitary or aggregated in cymes, spikes, or panicles and typically perfect and actinomorphic. Bracts and bracteoles are either herbaceous or scarious, flowers are regular with a herbaceous or scarious perianth of mostly five tepals, often joined. One to five stamens are opposite to tepals or alternating, inserting from a hypogynous disc, the anthers have two or four pollen sacs. In tribe Caroxyloneae, antheres have vesicular appendages, the pollen grains are spherical with many pores, with pore numbers from a few to 250. One to three carpels are fused to a superior ovary with one basal ovule, the diaspores are seeds or fruits, more often the perianth persists and is modified in fruit for means of dispersal. Sometimes even bracts and bracteoles may belong to the diaspore, more rarely the fruit is a circumscissile capsule or a berry. The horizontal or vertical seed often has a thickened or woody seed coat, the green or white embryo is either spirally or annular. The basic chromosome number is mostly 8-9, widespread in the Amaranthaceae is the occurrence of betalain pigments. The former Chenopodiaceae often contain isoflavonoids, in phytochemical research, several methylenedioxyflavonols, saponins, triterpenoids, ecdysteroids, and specific root-located carbohydrates have been found. With around 800 species that are C4-plants, the Amaranthaceae represent the largest group with this photosynthesis pathway among the eudicots, within the family, several types of C4-photosynthesis occur, and about 17 different types of leaf anatomy are realized. Therefore, this photosynthesis pathway seems to have developed about 15 times independently during the evolution of the family. About two-thirds of the C4-species belong to the former Chenopodiaceae, the first occurrence of C4-photosynthesis dates from the early miocene, about 24 million years ago, but in some groups, this photosynthesis pathway has evolved much later, about 6 million years ago

Ahe
–
Ahe, Ahemaru or Omaru, is an almost entirely-enclosed coral atoll, located in the northern Tuamotu Archipelago, just 14 km to the west of Manihi, in French Polynesia. Ahe Atolls ring shape is broken by only a small passage into the lagoon. Length 23.5 km, width 12.2 km and it has a land area of approximately 12 km2 and a lagoon area of 138 km2. As of 2012, Ahe Atoll had 553 inhabitants, the only village in Ahe is Tenukupara with approximately 100 inhabitants. It is located on an island in the side of the Atoll. Geographically Ahe Atoll is part of the King George Islands subgroup, there are several pearl farms in Ahes lagoon. In the late 1970s, the famous single-handed sailor Bernard Moitessier lived on Ahe for a couple of years, the first recorded Europeans to arrive to Ahe Atoll were Dutch mariners Willem Schouten and Jacob Le Maire in 1616. Ahe was later visited by the historic United States Exploring Expedition, charles Wilkes called the atoll Peacock Island after one of the ships of the expedition. This atoll has sometimes suffered damages caused by cyclones, Ahe has a territorial airport which was inaugurated in 1997.

Communes of France
–
The commune is a level of administrative division in the French Republic. French communes are roughly equivalent to civil townships incorporated municipalities in the United States or Gemeinden in Germany, the United Kingdom has no exact equivalent, as communes resemble districts in urban areas, but are closer to parishes in rural areas where districts are much larger. Communes are based on historical geographic communities or villages and have received significant powers of governance to manage the populations, the communes are the fourth-level administrative divisions of France. A French commune may be a city of 2.2 million inhabitants like Paris, communes typically are based on pre-existing villages and facilitate local governance. All communes have names, but not all named geographic areas or groups of people residing together are communes, a commune is a town, city, or municipality. Use of commune in English is a habit, and one that might be corrected. There is nothing in commune in French that is different from town in English. The French word commune appeared in the 12th century, from Medieval Latin communia, as of January 2015, there were 36,681 communes in France,36,552 of them in metropolitan France and 129 of them overseas. This is a higher total than that of any other European country. The whole territory of the French Republic is divided into communes and this is unlike some other countries, such as the United States, where unincorporated areas directly governed by a county or a higher authority can be found. There are only a few exceptions, COM of Saint-Martin and it was previously a commune inside the Guadeloupe région. The commune structure was abolished when Saint-Martin became an overseas collectivity on 22 February 2007, COM of Wallis and Futuna, which still is divided according to the three traditional chiefdoms. It was previously a commune inside the Guadeloupe region, the commune structure was abolished when Saint-Barthélemy became an overseas collectivity on 22 February 2007.88 square kilometres. The median area of metropolitan Frances communes at the 1999 census was even smaller, the median area is a better measure of the area of a typical French commune. This median area is smaller than that of most European countries. In Italy, the area of communes is 22 km2, in Belgium it is 40 km2, in Spain it is 35 km2, and in Germany. Switzerland and the Länder of Rhineland-Palatinate, Schleswig-Holstein, and Thuringia in Germany were the places in Europe where the communes had a smaller median area than in France. The communes of Frances overseas départements such as Réunion and French Guiana are large by French standards and they usually group into the same commune several villages or towns, often with sizeable distances among them
