History provides us with many examples of notable diasporas.
This is an incomplete list, which may never be able to satisfy particular standards for completeness. You can help by expanding it with reliably sourced entries.
Note: the list below is not definitive, and includes groups that have not been given significant historical attention. Whether the migration of some of the groups listed fulfills the conditions required to be considered a diaspora may be open for debate.
Eurominority.eu map (the European Union) Peoples of the World, includes some diasporas and underrepresented/ stateless ethnic groups - 
Argentine diaspora - People from Argentina known as Argentines whom live overseas in communities across western Europe (esp. Spain, Italy, Germany, France and the U.K.), North America (the U.S., Canada and Mexico) and elsewhere (i.e. Australia), mainly are political refugees from the military junta in the late 1970s and 1980s, (see also Argentine Americans).
Chilean diaspora - A small but widespread community, mostly of political refugees who fled the Augusto Pinochet regime after the 1973 coup. Overseas Chilean communities are in Argentina, Australia, Brazil, Canada, France, Great Britain, Italy, Mexico, Spain, Sweden and the U.S. (see Chilean Americans), but smaller communities are found in Belgium, Japan, Norway, New Zealand, and the Netherlands. During the Pinochet era, many refugees moved to East Germany when it was a communist country before reunification with Germany in 1990.
Colombian diaspora - over five million Colombians, either displaced by war, left for economic opportunity, and placed in exile to avoid political persecution. The Colombian diaspora lives across the Americas (i.e. Canada, Mexico, Costa Rica, and South American nations, especially Venezuela), and across Europe (i.e. Spain, France, Italy, Germany and the United Kingdom). The largest overseas Colombian population is the U.S. where they are over 2 million Colombian Americans, one of the largest Latino nationalities in the country.
Danish people a.k.a. Danes who originate in the small Nordic country of Denmark. They have historically migrated all over Europe, and about a million Danish emigrants in the last two centuries to all the world's six continents. An example of Danish culture overseas is in Solvang, California in the US.
Flemings, a subgroup of Dutch/Low German speaking people of the country of Belgium, about 50-55% of the country's population speaks Flemish, one of Belgium's two major and three official languages. Flemings migrated to all the six continents of the world, sometimes in droves to nearby countries of France and the Netherlands, other European nations of the UK, Germany and Sweden, and they founded new settlements. The Azores, a Portuguese territory was once called the Islas de las Flamandes (the Fleming Islands) in the 16th century. The West Flemish population in the Nord département of France struggle to preserve their endangered language.
Frisians, an ethnic group related to the Dutch live in the Frieslands on the northern half of the Netherlands, along with northwestern Germany and southernmost Denmark. The Frisians have their own language, history and customs. Frisians are thought to date back 5,000 years, migrated to the Rhine delta by the North Sea and were successful in draining out the marshes to make it inhabitable to establish cities and farmland. Frisians also migrated worldwide, a number of them were employed in the oceanic fishing markets.
Dominican people from the Dominican Republic formed a Dominican diaspora. Today, over a million Dominicans live in the US (see Dominican American), followed by Canada, Latin America (see Dominican Argentine), Spain and elsewhere. Dominicans lived outside the country in over a century (since 1900) but especially since the 1960s, Dominicans leave the country in search of available work and employment opportunities. Dominican immigration to Puerto Rico beginning in 1990 became very high in numbers per ratio to Puerto Rico's population, including illegal entries on dangerous rafts through the Mona Passage between the two islands (see Hispaniola).
Ecuadorian diaspora - People from Ecuador who reside in countries across the Americas (i.e. the U.S., see Ecuadorian Americans, also in Canada, Mexico, Argentina and Brazil), Europe (esp. Spain and Italy, with some in France and elsewhere), and smaller numbers in Japan and Australia.
EgyptianCopts, members of the Coptic Christian Church based in Egypt for about 2,000 years. Copts are thought to be connected with cultures and peoples of Ancient Egypt, then the religion was displaced by the arrival of Islam 1,400 yrs. ago. About 3 million Coptic Christians live around the world, the largest numbers are in North America and Australia; and Great Britain, Germany, Greece, Italy, Norway and Sweden in Europe.
Eritrea - Around half a million of the total five million Eritreans fled the country during the thirty-year Eritrean War of Independence. They have formed communities all over the western world (i.e. US in Washington D.C., and Los Angeles; and Europe: Sweden, Germany and Italy). There are more than half a million Eritreans in refugee camps (most in Sudan).
Estonians - When Estonia was invaded by the Soviet Army in 1944, large numbers of Estonians fled their homeland on ships or smaller boats over the Baltic Sea. Many refugees who survived the risky sea voyage to Sweden and/or Germany later moved from there to Canada, the United Kingdom, the United States and/or Australia. Also, with the June deportation of 1941 and March deportation of 1949, the Soviet Union forcibly transferred tens of thousands of Estonians to Siberia. Some of these refugees and their descendants returned to Estonia after the nation regained its independence in 1991. The Russian Empire displaced a fairly high number of Estonians into exile, maybe the number of descendants (the 3.5 million outside Estonia) to have assimilated into Russian society. The Estonian people are generally small in size (0.9 million within Estonia), but doesn't it include Estonian sub-groups: the Chudes, Livonians, Setos and Voros in neighboring lands of Russia, Latvia and Lithuania. There is no way to know the corrected number of Estonians, unless to count 100,000 dual nationals in the former USSR or the number of expatriates in the EU countries (esp. Finland).
Filipino diaspora is a large-sized diaspora made up of a variety of ethnic, linguistic and regional groups that are originally from the Philippines live around the world. Many have left the Philippines after its independence in 1946 from U.S. territorial rule, often for East Asia, Southeast Asia, Australia, New Zealand, Guam and Northern Marianas, North America, Europe, and the Middle East. Overseas workers have their own political party in the Philippine Congress.
The Acadian diaspora - the Great Expulsion (Grand Dérangement) occurred when the British expelled about 10,000 Acadians (over three-fourths of the Acadian population of Nova Scotia) between 1755 and 1764. The British split the Acadians between different colonies to impose assimilation. Most of the French-speaking Acadians resettled in the then French colony of Louisiana, now a state of the US where the "Cajuns" influenced the ethnological background of Louisiana and its cultural center of New Orleans, along with high admixture with Anglo-American, African, Spanish and other ethnicities introducing Jazz music and Creole cooking.
Walloons, a sub-group of French-speaking peoples in the southern half of Belgium and Luxembourg. In Belgium, due to Walloon culture, the French language was historically official, then the Flemish language and German in the easternmost parts are given co-official status. Many Walloon miners, factory workers and farmers migrated to France, Germany, Netherlands, Sweden and the UK; and other French and Dutch/Belgian colonial lands (i.e. Zaire).
"Speak French, Be Clean" written across the wall of a Southern French school, a byproduct of the French Government policy to eradicate Occitan and all regional languages in the late 19th and early 20th centuries.
Occitans are persons from Southern France, some are known to speak the Occitan language or Langue D'Oc for thousands of years, but in general decline from pressures by the French Republican government since the early 19th century. Occitans were often felt denied the right of their cultural heritage and some relocated out of France in quiet protest to other countries, esp. French-speakingCanada and other parts of La Francophonie (French Empire and French-speaking areas of Europe). Also there have been Occitan-speaking settlers in Pigüé, Argentina; sporadically Mexico and Chile; and even into the US in Valdese, North Carolina. Occitania is a regional-cultural movement that developed since the 1970s throughout the southern half of France with adjacent parts of Switzerland, Italy and Spain.
"Ossi(e)s" - a term for former East Germans of the former East Germany or the German Democratic Republic in contrast to the "Wessies" or West Germans. The two countries reunified in 1990, but there is a level of Ostalgie (means East-Nostalagia) for the past and cultural aspects of East Germany. When the Berlin Wall fell and the East-West German border was demolished, hundreds of thousands of Eastern Germans moved to the west side not only for freedom, but for the additional quality of life and economic opportunities available in the west, but after reunification a good percentage returned to what is now the same country. The 5 states of the former East (see New states of Germany) remained culturally distinct, mainly the older generation whom grew up in the GDR era. In 1989, there was an influx of East Germans into opened countries of the Soviet Bloc: Hungary, Czechoslovakia and Poland with some western embassies, esp. East Germans went to obtain passports from the Federal Republic of (West) Germany; and others went to neutral nations like Austria, Belgium, Denmark, Netherlands, Scandinavia and Switzerland for political reasons as some were still sympathetic to communist ideals. Some smaller numbers of East Germans chose to move in various countries of Western Europe and the Americas as well the former Soviet Union, but most returned home in the course of the 1990s. Germany may be reunified, but some "Ossie" cultural identity remains.
Gerashi diasporas - The people of Gerashi origin (of Iran) who have migrated to the Arab States of the southern Persian Gulf in search of necessities and basic human rights. It has continued since the early 20th century bombing of the city by Reza Shah and the federal forces.
Greek diaspora - refers to any ethnic Greek populations living outside the borders of Greece and Cyprus as a result of modern or ancient migrations. There is a Department of Diaspora Affairs in the Greek government. An estimated three million Greeks live in North America (the United States and Canada), Africa, Australia (especially Melbourne, the third largest 'Greek' city), across Europe - the largest groups being established in Germany, Sweden and Belgium - and the Middle East. Ancient Greek communities in what is now Turkey were destroyed due to the fallout from World War I and persecution. A Greek community remains in Istanbul according to the terms of the Lausanne treaty, but persecution in the 1950s and 1960s led most to flee. Only a small community (Pontic Greeks) remain in Turkey. A similarly ancient community of Greeks in Alexandria and Cairo was ordered to leave Egypt in the 1960s under Nasser's nationalisation programme. In addition, many Greek-speaking Cypriots migrated to Britain in the 20th century.
Hapa - The modern term for mixed-race persons of Asian-Americans of white/Caucasian and Native Hawaiian ancestry. (see also Multiracial American) They tend to live across the US and western Canada, due to historic migration of Hawaiians into North America.
Inuit people, their homeland spans across 4,000 miles (6,400 km) of northern most reaches of North America along the Arctic Ocean. About 800,000 Inuit (a.k.a. "Eskimos") live in four countries: The U.S. (Alaska), Canada (Nunavut is a territorial government established in 1999), Greenland (the "Greenlandic" people, the majority are of Inuit and Danish-European ancestry), self-ruling territory of Denmark, and about 3,000 in the Chukchi Peninsula, Russia facing the Bering Strait.
The Vietnamese diaspora - fled communist rule in Vietnam following their victory in the Vietnam War (see South Vietnam) went to the United States (see Vietnamese Americans), the migration peaked in the 1980s and 1990s (esp. the largest Vietnamese-American community is in Orange County, California). The Vietnamese also went to Canada, France (and overseas territories), Germany (also the Vietnamese guest workers in the former Communist East Germany), Italy, the Middle East, Australia, and other Asian countries (most went to Hong Kong, when it was a British colony, before the handover to the People's Republic of China in 1997, and Macau, which was under Portuguese rule until the handover to the People's Republic of China in 1999).
Some millions of Indochinese were of ethnic Chinese descent, the majority of Chinese/Sino-Vietnamese from Vietnam, Chinese-Cambodians of Cambodia and Thai-Chinese of Thailand had emigrated in the late 20th century.
Minangkabau diaspora - two of three Minangkabau people live in diaspora. Matrilineal system indirectly caused the diaspora in Minangkabau community. Nowadays, over a million Minangkabau people living outside of Indonesia, mainly in Malaysia and Singapore, but they recently joined the Indonesian emigration to Australia, China, Europe, Japan, South Korea, Taiwan and the Philippines.
Javanese diaspora - occurred in the Dutch colonial era. Vast numbers of Javanese send to other of Dutch colony as coulies. Most of them were send to Suriname, New Caledonia, and East Sumatra, as well in the late 20th century the Javanese were introduced to the island of New Guinea by Indonesian government endorsed settlement programs in the West Papua province. But others live in Malaysia, Europe, North America, the Middle East, South Africa and Australia.
Indo diaspora - During and after the Indonesian National Revolution, which followed the World War II, (1945–1965) around 300.000 people, pre-dominantly Indos, left Indonesia to go to the Netherlands. This migration was called repatriation. The majority of this group had never set foot in the Netherlands before.
Irish diaspora - consists of Irish emigrants and their descendants in countries such as the United States (see Irish Americans), the United Kingdom, Canada, Australia, New Zealand, Argentina, South Africa, and nations of the Caribbean and continental Europe, where small but vibrant Irish communities continue to exist. The diaspora contains over 80 million people and it is the result of mass migration from Ireland, due to past famines and political oppression. The term first came widely into use in Ireland in the 1990s when the then-President of Ireland, Mary Robinson began using it to describe all those of Irish descent. Notable people of the global Irish diaspora are United States presidents John F. Kennedy, Ronald Reagan, Bill Clinton, Barack Obama and Chilean liberator Bernardo O'Higgins.
Istrian exodus- The real diaspora of the 20th century came after the end of World War II, with 350,000 Italians leaving their homeland on the eastern front after the capture of Istria and Dalmatia by the Yugoslavs. Most of them were relocated in Italy itself; a lower percentage flew overseas (the racer Mario Andretti for example).
Jaffnese/Ceylonese Diaspora - refers to the diaspora of Sri Lankan Tamils, especially those post-1983 due to the civil conflict in Sri Lanka. This has created huge Tamil communities in countries such as Canada, the United States, Australia, the United Kingdom, Germany and other European countries. In many ways, the Jaffnese Diaspora is compared to the Jewish Diaspora, both historically, socially and economically. It is a subset of the greater Tamil Diaspora.
Jamaican diaspora - An estimated 3 million Jamaicans live outside the island country of Jamaica, an English-speaking majority African descendant country in the Caribbean. The main destinations for Jamaican immigration in the 20th century are the U.S., Great Britain and Canada. But, Jamaican immigration across the Caribbean, to Latin America, Australia and New Zealand, and even Africa are well noted. Jamaicans living aboard, such as Bob Marley introduced the music form of reggae to the international music market in the 1970s.
Okinawans - An Asian people closely related to the Japanese in terms of culture and language, from the island of Okinawa, politically part of Japan since 1878. After WWII, the U.S. briefly ruled Okinawa from 1945 to its return to Japanese rule in 1972. Since then, tens of thousands of Okinawans settled in the U.S. and in the 1960s, massive settlement programs of Okinawan farmers into Latin America, the majority in Brazil and Peru, and some Okinawan transplants in Ecuador, Bolivia (the Santa Cruz, Bolivia province area) and Paraguay (i.e. the Gran Chaco) to develop their countries' agricultural farmlands.
Jewish diaspora - in its historical use, refers to the period between the Roman invasion and subsequent occupation of Judea beginning CE 70, to the establishment of Israel in 1948. In modern use, the 'Diaspora' refers to ethnic Jews who continue to live outside of Israel. A minor faction of Jews, particularly assimilationist Reform-Jews and recent reform-converts, do not regard themselves as part of a diaspora community.
Jewish groups and histories greatly vary from one another in each country, notably large communities represented in the global Jewish diaspora. Currently, North America and Europe are home to the vast majority of diaspora Jews.
Sephardic-Jewish Diaspora - in 1492 Isabella and Ferdinand of Spain expelled all persons who were not members of the Roman church specifically Jews and Christians of Jewish origin. The Sephardi Jews, as they were known, resettled across Southern Europe, North Africa and the Middle East, but others went to Germany and the Netherlands (where they merged with the local Ashkenazi), and some went to Britain, North and South America, and other colonies of the British and Spanish empires by the late 16th century.
Kaszubian diaspora - the Kaszubians are a Slavic, Roman Catholic people who have lived and maintained their language and unique traditions for centuries despite living on the boundary between the Germanic and Polish cultures. Between 1850 and 1900, many Kaszubians moved to North America, to Brazil, and to Australia and New Zealand.
Khmer people - The main ethnic group of Cambodia have historically emigrated in the 18th, 19th and esp. 20th centuries. The largest Cambodian communities are in the US, Canada, France, Thailand, Vietnam, China (with Hong Kong), Malaysia, Singapore, Australia, New Zealand, Great Britain and Arabia (i.e. the U.A.E).
Korean diaspora - a people from the Korean peninsula located between China and Japan. The first wave of Korean diaspora was during the Japanese colonial occupation (1910–1945), the peace treaty division of the Korean peninsula into two republics, the Korean War (1950–53) produced a wave of millions of war refugees who fled to the United States, Canada, China, Japan, the Philippines, South Vietnam until 1975, and the USSR, now Russia. Today, Korea remains a politically divided geographic unit. South Korea was under military rule 1953-1987, now a civilian democracy, but economic problems and a sense for adventure made over 500,000 South Koreans emigrate to the United States and Canada, and 100,000 more to Europe, Australia and South America (i.e. Brazil and Argentina). North Korea remains under an isolationist military state under Communism since 1948, while millions of political refugees fled to nearby China for freedom in the late 20th century.
Kurdish diaspora - Kurdish diaspora is the Kurdish populations found in regions outside their ancestral homeland Kurdistan. The United Nations declared the Kurds the largest ethnic nationality (over 40 million) without a country in the world.
Lebanese diaspora - An estimated 15-16 million Lebanese live worldwide. Over half of the country's population are of Muslim faith and the rest are Christians,but in the world Christians Lebanese outnumber Muslims by 3:1. Lebanese are found in over 150 countries, the largest known Lebanese community is in the Brazil, U.S. followed by Canada; and Australia, where Lebanese immigration has occurred in large numbers since the civil war. Although there are millions of Lebanese descendants in Europe, the Middle East, South Asia and Latin America, the Lebanese are also present in much of the continental span of Africa.
Lithuanian diaspora - the majority of post-WWII Lithuanians live in North America (Canada and the United States) and across Europe (France, Germany, Ireland, Poland, Sweden, Netherlands and England), but are scattered across Russia and the former USSR, and smaller numbers in Mexico and Brazil. The Lithuanians and their ethnological kin, the Latvians may be the oldest Indo-European speaking peoples known and may resided in the Baltic states for 5,000 years. Between 1880 and 1910, over 40,000 Lithuanian Jews immigrated to South Africa to avoid persecuation. To date around 80% of the 75,000 Jews in South Africa (around 60,000) are of Lithuanian descent.
Latvian diaspora - the majority of Latvians whom left Latvia in WWII reside in North America (the US and Canada), across Europe mainly in Eastern countries and the former USSR with just as many in Western Europe and Scandinavian nations, and the rest in former Latvian lands in the Baltic states (Estonia, Lithuania, Poland, Russia and Belarus). The most Russified of the three Baltic states, Latvia struggles with the issue of national identity after one million ethnic Russians and other Russian speaking people settled there since 1940.
Latgalians, a predominantly Catholic people in eastern Latvia in the region of Latgale and have a close history with Lithuania, due to differences in church denomination between them and Latvians who are a majority Lutheran along with Estonians not ethnically related to Latvians and Lithuanians.
Algerian-French residents make up an estimated 5 to 8 percent of the ethnic makeup of France's population, despite the French government does not keep data records on race and ethnicity. Algerians resided in France for over 150 years as a result of the French colonial period in Algeria from 1830 to 1962, when the seven-year Algerian War brought independence. The largest North African French communities are in (and surrounding) Marseille, Paris, Lille, Nice and Lyon. A growing community in Canada and UK came to light during the 90s and the Algerian Civil War.
Moroccans are found throughout the world, mainly in the Maghreb nations of North Africa, Egypt and the Middle East (a large Jewish colony in Israel) and expatriate communities in Europe (i.e. the largest being in France, followed by Belgium, Spain, Italy, Germany, the Netherlands, Sweden, Norway, Portugal, Great Britain and Ireland) developed by Moroccan immigration since the 1950s.
Maltese diaspora: established mainly in the United Kingdom, Australia, Canada and the U.S. as well throughout Europe and the Americas. Large communities existed in Algeria, Tunisia, Libya and Egypt but were mostly dispersed by the mid-20th century when these countries acquired independence. Since Malta's membership of the EU in 2004, new communities were established such as the one in Belgium.
Moluccan diaspora - Begins in 1950s as the result of the end of its occupation over Dutch Indies, the Netherland government decided to transport around 12,000 Moluccan KNIL (The Royal Netherlands East Indies Army) the remaining men and their families to Europe. They were discharged on arrival and 'temporarily' housed in camps until it was possible for them to return to the Moluccan islands. Although The South Moluccan Republic has been declared on 25 April 1950, this movement was defeated by Indonesian government and the rest of RMS (Republik Maluku Selatan) followers leave their homeland and formatting a Government in Exile in the Netherlands since 1966. Nowadays, at least 200,000 Moluccan living side by side with Dutch people and becoming the biggest ethnic groups outside native Dutch in The Netherlands. The second wave happened during the civil war in Maluku 1999 to 2003, causing over 800,000 left the country. Most of the refugees moved to United States (mainly concentrated in Maryland, Florida, California and New York), Netherlands, France, Israel (mostly by Moluccan Jewish), Italy, Denmark, United Kingdom, Russia (mainly in St. Petersburg), Australia, Brazil, Portugal and Austria. After prosecuted, scattered, and finally settle down among the nations, latest statistics reporting the number of Moluccan in diaspora including their descendants (make up to 1.4 million) is a bit smaller than those who are staying in Indonesia (nearly 2.5 million).
Moravian Church - has a nickname "the Moravian Diaspora" named from a religious, not ethnic' identity, having been founded in the province of Moravia, now in the Czech Republic. During the 16th and 17th centuries, religious persecution drove the majority of church members to other countries, and by the late 18th and 19th centuries, the church had managed to grow, thrive and survive. There are hundreds of thousands of Moravian church members in small communities in Europe (the Netherlands), the Americas (the United States), Africa (South Africa), east Asia (South Korea), the Indian subcontinent (India), and Oceania (Australia). However, the vast majority of these would consider themselves natives of the country where they live - the nickname (presumably) being of only historic interest.
Mormons, a Christian religious group whose official name is The Church of Jesus Christ of Latter-day Saints, headquartered in Salt Lake City, Utah, as well smaller other churches based on Mormonism. Just under 50 percent of all Mormons live in the United States, while about three-fourths of the population of Utah are Mormon and form large minorities in 8 to 10 other Western U.S. states; and California is said to have the most LDS church members by population. Mormonism began as a small following of Christians who followed the teachings of Joseph Smith, founder of the Latter Day Saint movement in the early 19th century. The following were often forced to migrate and lived in the states of New York, Ohio, Illinois and Missouri by 1840. The Mormons were expelled by mob violence (Joseph Smith was killed) and persecution by neighbors in the 1840s and their new leader Brigham Young took the Mormons throughout the Great Plains and Rockies to settle the Salt Lake Valley, then a part of Mexico but soon to become part of the U.S., in 1847. Mormons play a fundamental role in the development of Utah and most other Western states, with Utah becoming a state in 1896. Today, an estimated 13 million Mormons are found around the world, after missionary activity and conversion programs extended the L.D.S. and other Mormon-based churches worldwide, the largest concentrations of Mormons other than the U.S. are Mexico, Canada, South America, the South Pacific (esp. in Fiji, Samoa and Tonga), Scandinavia, Britain and East Asia, but the fastest growth in Mormonism in the late 20th century was in Africa, India and Eastern Europe.
Montenegrins, a diaspora of South Slavs in the country of Montenegro who had a 650-year tradition of independence and autonomy. They were a former republic of pre-1991 Yugoslavia and later a co-republic with Serbia until Montenegro declared independence in 2006. Over 1.3 million Montenegrins live in the Balkans, while half a million more are in Western Europe, 600,000 live in the US and another 1 million around the world (i.e. Canada, Brazil, Argentina, South Africa and Australia).
New CaledoniaKanaks - a Melanesian people native to the overseas French territory brought to Australia and New Zealand, and across Polynesia (The French territory of Tahiti) as agricultural workers in newly founded plantations during the late 19th and early 20th centuries. Most Kanak laborers in Australia were deported back to New Caledonia in the 1910s due to racial fears of Kanaks live among the country's white European-descent majority. Today, an estimated 30,000 Australian descendants of Kanaks live in the state of Queensland, where the main concentration of Australian plantation agriculture took place.
Newfie, a colloquial name for people from the Canadian province of Newfoundland and Labrador, originally for inhabitants of the Island of Newfoundland. The Newfie diaspora frequently emigrated to other provinces of Canada foir employment opportunities in the tens of thousands since the 1920s, while some Newfoundlanders went to the US and the UK in a lesser extent. Newfoundland became Canada's 10th province in 1949, after 350 years of British rule.
Nigerian diaspora, people from the country of Nigeria, the most populous country in Africa. Over 3 million Nigerians live outside the country, as immigrants are known to live in the US, the UK and South Africa, among other nations.
The Five congressional districts in Oklahoma. The Map shows districts 1 and 2 with parts of 3 4 and 5 are former Indian Territory from 1830 to 1907. The largest American Indian tribal groups live there in the eastern half of the state, most notably the Cherokee, Choctaw and Creek Indian Nations, whose populations mostly live outside of them.
Oromo and other Ethnic Groups of Ethiopia, an estimated 30-50 million who have gone by different ethnological names like "Abyssinians", "Erthyreneans" and "Amharics". Ethiopia's population is highly diverse. Most of its people speak a Semitic or Cushitic language. The Oromo, Amhara, and Tigreans make up more than 3/4s of the population, but there are more than 80 different ethnic groups within Ethiopia. Some of these have as few as 10,000 members. They live across the continent of Africa, while a mass movement of Ethiopian immigrants during the 20th century into the Middle East (one major area of choice is Israel), Europe, South Asia, East Asia, Australia, North America (esp. the U.S. and Canada), and Latin America has created a global Ethiopian diaspora.
Pakistani Diaspora - People who are originally from Pakistan and have settled abroad. Are mainly economic migrants and settled mainly in the Middle East and Britain. The total population is approximately 7 million.
Persian Diaspora - A.k.a. Iranians are a major community in Los Angeles, and California in the US, as the major number of Persians in Los Angeles are located in the community of Westwood, Los Angeles a.k.a Little Persia, and even the mayor of the nearby city of Beverly Hills is Persian (see Iranian Americans). Other large Iranian communities exist throughout the U.S., Canada, Europe, the Middle East, east Asia and Australia, make up a total of 10 million belonged to the Persian/Iranian diaspora, the majority are political refugees who fled the overthrow of the Mohammad Reza Pahlavi regime in 1978 and Islamic Revolution of 1979.
Peruvian diaspora - People who originally came from Peru. The largest Peruvian communities are in the United States (see Peruvian Americans), Canada, Europe (i.e. Spain, Italy and France), Japan and Australia.
Puerto Rican diaspora - a mass migration of Puerto Ricans from the island territory of Puerto Rico to the United States mainland began during the first half of the 20th century and has become a subject often studied in colleges, because of Puerto Ricans who achieved success in the United States. The largest Puerto Rican communities in the mainland U.S. are in New York City (about 1 to 2 million in the New York City metro area), New Jersey, Pennsylvania and Florida, but other Puerto Ricans live in all 50 states including Hawaii, and also a smaller community each in Canada and Spain in Europe. Some Puerto Ricans from New York call themselves Nuyoricans. Puerto Ricans everywhere commonly refer to themselves as Boricuas, referring to Borinquen, or Puerto Rico's Native American name before the arrival of the Spanish.
Rhodesian diaspora. Southern Rhodesia had the distinction amongst Britain's African colonies of being a self-governing Crown Colony. As a result most Southern Rhodesians did not regard Great Britain as home but instead regarded Southern Rhodesia as home, though they did recognise cultural ties to Great Britain. During and following the Bush War (1966–1979, during which period the former Southern Rhodesia was known as Rhodesia) more than half of Rhodesia's population of European descent emigrated mainly to Australia, New Zealand and Canada. For many South Africa was the first destination, where some have settled, but most of these migrants where transient and later reached further destinations. Others recognising their cultural ties to Great Britain emigrated there. This trend continued after Rhodesia became Zimbabwe-Rhodesia in June 1979 and increased when Zimbabwe-Rhodesia became Zimbabwe in March 1980 (following a brief 85-day period during which the land's name formally reverted to "Southern Rhodesia" for reasons of political expediency); it is estimated that the population of European descent decreased from a peak 275,000 in 1970, to 120,000 in 1999. British citizens resident in the region joined in this migration and did not in all cases return to Great Britain, or in some cases did so only temporarily before moving on. Northern Rhodesians of European descent also emigrated to these same destinations, though their migration began earlier when Northern Rhodesia became Zambia in 1964 and was not the result of war but economic pressure. People of European descent also emigrated from Nyasaland after 1964 and followed the same routes as Northern Rhodesians, for the same reason. See: Federation of Rhodesia and Nyasaland.
Romanians - who emigrated for the first time in larger figures between 1910 and 1925, and left in mass after the fall of communist regime in Romania in 1989, and comprise the Romanian diaspora, are found today in large numbers in Italy, Spain, Portugal, France, Germany, Greece, Israel, Russia, Turkey, the Netherlands, the U.K., China, Japan, Australia, the U.S., Canada, Mexico, Brazil and Argentina. Today there are over 12 mil. people of Romanian descent outside the country.
Scottish diaspora - includes the Auld Alliance and the Scottish Wars of Independence which led countless Scots to emigrate to mainland Europe to escape persecution and hardship. The Highland clearances which depopulated large parts of the Scottish Highlands and had lasting effects on Scottish Gaelic culture; the Lowland Clearances which resulted in significant migration of Lowland Scots to Canada and the United States after 1776; the Ulster-Scots, descended primarily from Lowland Scots who settled Ulster during the Plantation of Ulster in the 17th century and subsequently fled to the Americas in mass numbers throughout the 18th century due to religious and cultural persecution as well as other socio-economic factors. Other Scots and Ulster Scots went to Australia, New Zealand, South Africa and a smaller but important community in Argentina. (See also British diaspora, above).

Tamil diaspora - denotes people of Tamil Nadu and Sri Lankan Tamil origin who have settled in many parts of rest of India, Sri Lanka, Malaysia, Singapore, Reunion, South Africa, Mauritius, Fiji, Guyana, Trinidad and Tobago, French Caribbean islands, Europe, Australia and North America (US and Canada).
The Romani (English terms: Gypsy, Gypsies) - a traditionally 'dispersed' people in Europe, with origins in South Asia (or perhaps, northern India) for 800-some years, are even more 'dispersed' today, following the Holocaust of Nazi Germany. (See Some names for the Roma) Over 10 million Romani live across Europe, the majority in Eastern countries (Russia, Ukraine, Belarus, Latvia, Lithuania, Romania, Bulgaria, Hungary, Poland, Albania, Greece, Serbia, Slovakia, Slovenia, Croatia, Bosnia and Herzegovina, Montenegro and Macedonia), and estimates of 250,000 Romani are known to live in North America (the US and Canada).
Spanish diaspora - Refers to the migration of millions Spanish people over the last 500 years all over the world, for a great variety of reasons, especially to America, Africa (Spanish Guinea, Spanish Morocco, and the Canary Islands), and other Spanish territories in Europe. This has resulted in the diffusion of the Spanish language and the large number of Spanish names in the places mentioned. During the 20th century, the Spanish diaspora was increased due to the political and economic emigrants who left Spain during the Francoist dictatorship (1930s but his death in 1975 brought democratic reform back to Spain). Notable communities were established in Argentina, Cuba, France, Italy, Mexico, Russia, the United Kingdom and across Latin America.
Sudanese from the African nation of Sudan and the new independent country of South Sudan inhabited by the mostly Christian Dinka and Nuer peoples. Many Sudanese of both countries immigrated into Europe, esp. the UK and scattered across the Middle East. There has been substantial growth of Sudanese in the US and Canada, esp. in the Midwest and Central States (see Sudanese American), and were areas of resettlement of tens of thousands of (many Southern) Sudanese refugee children known the Lost Boys of Sudan in the 1990s and 2000s (decade).
Swedish diaspora. Large numbers of Swedes (and Swedish speaking Finns from Finland also under Russian rule) migrated to the US in the late 19th and early 20th centuries. It is estimated that about eight million Americans have some Swedish ancestry. Swedish Americans constitute 10% of the population of Minnesota and other large numbers settled in Wisconsin, Illinois, New York and Pennsylvania. A large colony of Swedes settled towns in the US like Lindsborg, Kansas and Kingsburg, California in the late 19th century. Large Swedish migration took place in Canada in the same time period along with other ethnic Scandinavians from Norway, Denmark and Iceland. Smaller waves of Swedish expatriates live across Europe, east Asia, Australia and Latin America, usually made up of retirees and businessmen in the late 20th century. It is estimated that between 80,000 and 100,000 Swedes live in Norway (2012), many of whom being young workers.
Swiss diaspora, some 9% of Swiss citizens live across the globe. Swiss nationals and descendants live in the U.S., Canada, Mexico, Peru, Bolivia, Argentina, Brazil and nearby nations of France, Germany, Italy and Austria. In the late 19th century, an immigration settlement program brought tens of thousands of Swiss Germans, ethnic Germans and Austrians alike into southern Chile, and the imprint of Germanic culture remains strong there. Also to note West African nations such as Liberia and Ghana are known for several thousands of Swiss expatriates.
Ukrainian diaspora, represented by Ukrainians who left their homeland in several waves of emigration, settling mainly in the Americas (United States, Canada, Mexico, Brazil and Argentina), but also Australia, east Asia (China) and across Europe. Also includes the tens and millions of Ukrainians who migrated from Ukraine to other parts of the former Soviet Union (mainly Russian Federation) during the Soviet time. Ukrainians in the Middle East should be noted and the large-scale Ukrainian with Russian Jewish emigration to Israel.
Ruthenians and Carpathians, self-titles for Slavic peoples from the small region of Ruthenia, encompasses easternmost Slovakia, southeast parts of Poland, northern edges of Hungary and westernmost Ukraine, had preserved a unique ethnocultural identity, but lacked an independent country of their own for almost a millennia. In the late 19th century and again between World Wars I and II, over a million Ruthenians fled their homeland and settled across Western Europe (France, Germany and Austria), North America (the U.S. and Canada) and the USSR (Russia), but lesser numbers settled in East Asia (China), the Middle East (Turkey), South America (Brazil) and Australia in the late 20th century.
The Venezuelan diaspora - People from Venezuela who live outside of their territory: Mainly in the United States, Mexico, Brazil, Spain and Italy. Most of them arrived to escape from the military dictatorship of the 1950s and the political repressions in the 1960s. Recently, there's been a growing number of Venezuelans in Canada almost all of them working for the Oil industry after the 2002 strike. See also Venezuelan American. Since the arrival of President Hugo Chávez, a significative growing number of young Venezuelans are feeling their country in search of better living standards and work opportunities.
Welsh diaspora - The Welsh (or in the Welsh language - Cymry) are a Celtic people from Wales one of the four countries of the United Kingdom who manage to preserve their Celtic heritage after a millennia of English and then British rule. An estimated 5 million people of Welsh ancestry live globally in areas formerly part of the British Empire (Canada, Australia, New Zealand and lesser numbers in Latin America) and about 2 million Americans are of Welsh descent. In the 19th century, over 500,000 Welsh miners migrated out of Wales throughout the British Empire, western Europe, the Americas (the U.S. such as Jackson County, Ohio was nicknamed Little Wales) and South Africa for mining jobs, but others came as shepherds, factory workers and fishermen. The Welsh fought hard to preserve their culture, such as the revived Welsh language and their sense of identity in face of forced assimilation to the Anglo-British fabric. In the late 19th century, a small but solid group of Welsh people settled in Patagonia, creating the Welsh community known as Y Wladfa that survived to this day in the Argentinan provinces of Chubut and Santa Cruz. Many there are bilingual in Spanish and Welsh.
Various Native Americans of the United States have diaspora legends, stories and identity, but this applies only after contact with Europeans and removal of entire tribal peoples by post-colonial white European governments from the 16th to 19th centuries.
Various ethnic minorities from areas under Russian and Soviet control following the Russian Revolution, continuing through the mass forced resettlements under Joseph Stalin.
Various groups fled in large numbers from areas under Axis control during World War II, or after the border changes following the war, and formed their own diasporas. Only a few larger sized ethnic groups and nationalities were able to restore autonomy after the fall of Communism and the disbanding of the Soviet Union (1990–91).
