In the whole world there are easily more than one hundred million people with recognizable Portuguese ancestors, due to the colonial expansion and worldwide immigration of Portuguese from the 16th century onwards to India, the Americas, Macau and East-Timor, Malaysia, Indonesia and Africa. Between 1886 and 1966, Portugal lost to emigration more than any West European country except Ireland. From the middle of the 19th century to the late 1950s, nearly two million Portuguese left Europe to live in Brazil and the United States. About 40 million Brazilians have relatively recent Portuguese background, due to massive immigration in the late 19th and early 20th centuries. About 1.2 million Brazilian citizens are native Portuguese (see Geni project Portuguese immigrants to Brazil).
Portuguese Sephardic Jews (mostly descendants) are also important in Israel, the Netherlands, the United States, France, Venezuela, Brazil and Turkey.
In the United States, there are Portuguese communities in New Jersey, the New England states, and California. In the Pacific, Hawaii has a sizable Portuguese element that goes back 150 years , Australia and New Zealand also have Portuguese communities. Canada, particularly Ontario, Quebec and British Columbia, has developed a significant Portuguese community since 1940.
Argentina and Uruguay had Portuguese immigration in the early 20th century. So has Chile where an estimated 50,000 descendants live, as the country's maritime industries attracted a small number of Portuguese as well. Portuguese fishermen, farmers and laborers dispersed across the Caribbean, especially Bermuda, Guyana, Trinidad, St. Vincent and the Grenadines, and the island of Barbados where there is high influence from the Portuguese community.
In the early twentieth century the Portuguese government encouraged white emigration to Angola and Mozambique, and by the 1970s, there were up to 1 million Portuguese settlers living in their overseas African provinces. An estimated 800,000 Portuguese returned to Portugal as the country's African possessions gained independence in 1975, after the Carnation Revolution, while others moved to Brazil and south to South Africa.
As of 1989, some 4,000,000 Portuguese were living abroad, mainly in France, Germany, Brazil, the United Kingdom, South Africa, Canada, Venezuela, and the United States.
Portuguese constitute 13% of the population of Luxembourg.
In 2006 there were estimates to be over half a million people of Portuguese origin in the United Kingdom, this is considerably larger than the around 88,000 Portuguese born people alone residing in the country in 2009 (estimation) (however this figure doesn't include British born people of Portuguese descent). In areas such as Thetford and the crown dependencies of Jersey and Guernsey, the Portuguese form the largest ethnic minority groups at 30% of the population, 20% and 3% respectively. The British capital London is home to the largest number of Portuguese people in the UK, with the majority being found in the borough's of Kensington and Chelsea, Lambeth and Westminster.
As a result of interracial marriage and cultural influence, there are Portuguese influenced people with their own culture and Portuguese based dialects in parts of the world other than former Portuguese colonies, most notably in Malaysia, Singapore and Indonesia, Barbados, Jamaica, Aruba, Curaçao, St. Vincent and the Grenadines, Trinidad and Tobago, Guyana, Equatorial Guinea and Sri Lanka.
