Scandinavia is a subregion of Northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. Scandinavia most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer to the Scandinavian Peninsula. In English usage, Scandinavia is sometimes used as a synonym for Nordic countries. Iceland and the Faroe Islands are sometimes included in Scandinavia for their ethnolinguistic relations with Sweden, Norway and Denmark. While Finland differs from other Nordic countries in this respect, some authors call it Scandinavian due to its economic and cultural similarities.

The Somali diaspora or Qurbajoogta refers to Somalis who were born in Greater Somalia and reside in areas of the world that they were not born in. The civil war in Somalia greatly increased the size of the Somali diaspora, as many Somalis moved from Greater Somalia primarily to Europe, North America, Oceania and South Africa. There are also small Somali populations in Asia. The UN estimates that in 2015, approximately 7 million people from Somalia were living outside of the country's borders.
Australians, colloquially known as Aussies, are the citizens, nationals and individuals associated with the country of Australia. This connection may be residential, legal, historical or ethno-cultural. For most Australians, these connections exist and are collectively the source of their being Australian. Australian law does not provide for a racial or ethnic component of nationality, instead relying on citizenship as a legal status, though the Constitutional framers considered the Commonwealth to be "a home for Australians and the British race alone", as well as a "Christian Commonwealth". Since the postwar period, Australia has pursued an official policy of multiculturalism and has the world's eighth-largest immigrant population, with immigrants accounting for 30 percent of the population in 2019.
Nordic and Scandinavian people in the United Kingdom refers to people from the Nordic countries who settled in the United Kingdom, their descendants, history and culture. There has been exchange of populations between Scandinavia and Great Britain at different periods over the past 1,400 years. Over the last couple of centuries, there has been regular migration from Scandinavia to Great Britain, from families looking to settle, businesspeople, academics to migrant workers, particularly those in the oil industry.
English Australians, also known as Anglo-Australians, are Australians whose ancestry originates wholly or partly in England. In the 2021 census, 8,385,928 people, or 33% of the Australian population, stated that they had English ancestry. It is the largest self-identified ancestry in Australia. People of ethnic English origin have been the largest group to migrate to Australia since the establishment of the Colony of New South Wales in 1788.
Hispanic and Latin American Australians refers to Australians who are of Hispanic, and/or Latin American origin irrespective of their ancestral backgrounds, and their descendants. Brazilian Australians make up the largest proportion of Latin American Australians, while Chilean Australians make up the largest group of Hispanic Australians, followed by Salvadoran Australians. Most Hispanic and Latin American Australians speak English but many continue to use Spanish or Portuguese as well.
Danish Australians are Australians with full or partial Danish ancestry. The majority of these people are part of the Danish diaspora.
Ethiopian Australians are immigrants from Ethiopia to Australia and their descendants. However, as Ethiopia is a multi-ethnic country with significant inter-ethnic tensions, not all individuals from Ethiopia accept the label "Ethiopian", instead preferring to identify by their ethnic group. In particular, various Oromo people use the term 'Oromo Australian' instead. In contrast, there are many individuals who prefer to label themselves as Ethiopian Australians. This is because they oppose labelling themselves based on their ethnicity as they see it as divisive and politicising their ethnic identity. This is common among the Amharic-speaking community along with ethnically mixed individuals, compared to others who stand by their ethnic identity.
European Australians are citizens or residents of Australia whose ancestry originates from the peoples of Europe. They form the largest panethnic group in the country. At the 2021 census, the number of ancestry responses categorised within European ancestral groups as a proportion of the total population amounted to more than 57.2%. It is impossible to quantify the precise proportion of the population with European ancestry. For instance, many census recipients nominated two European ancestries, tending towards an overcount. Conversely, 29.9% of census recipients nominated "Australian" ancestry, tending towards an undercount.
