Among countries with the highest number of overseas Chinese on each continent, the largest Chinese diaspora community is living in Indonesia, numbering more than ten million people. Most of these people are descendants from migrants born in China, who have moved to Indonesia a long time ago. On the contrary, a large part of overseas Chinese living in Canada and Australia have arrived in these countries only during the last two decades. China as an emigration country Many Chinese people have emigrated from their home country in search of better living conditions and educational chances. The increasing number of Chinese emigrants has benefited from loosened migration policies. On the one hand, the attitude of the Chinese government towards emigration has changed significantly. Overseas Chinese are considered to be strong supporters for the overall strength of Chinese culture and international influence. On the other hand, migration policies in the United States and Canada are changing with time, expanding migration opportunities for non-European immigrants. As a result, China has become one of the world’s largest emigration countries as well as the country with the highest outflows of high net worth individuals. However, the mass emigration is causing a severe loss of homegrown talents and assets. The problem of talent and wealth outflow has raised pressing questions to the Chinese government, and a solution to this issue is yet to be determined. Popular destinations among Chinese emigrants Over the last decades, English speaking developed countries have been popular destinations for Chinese emigrants. In 2022 alone, the number of people from China naturalized as U.S. citizens had amounted to over 27,000 people, while nearly 68,000 had obtained legal permanent resident status as “green card” recipients. Among other popular immigration destinations for Chinese riches are Canada, Australia, Europe, and Singapore.

As of 2024, over 35 million Indians were living across the world. Of this population, over 15 million were non-resident Indians (NRIs) and the rest were persons of Indian origin (PIO). Indians form the largest diaspora in the world.  Non-Resident Indians An NRI is an Indian citizen living abroad indefinitely for employment, education, business, or other reasons. If an individual spends less than 182 days in a financial year in India, they qualify as an NRI. NRIs can vote in India if they are physically present in their constituency during the voting period. However, NRIs are subject to different tax and investment regulations than Indian citizens. Persons of Indian Origin Persons of Indian origin refer to people who at some point held Indian citizenship or have Indian ancestry, with some exceptions. The Overseas Citizenship of India (OCI) is granted as a lifelong and multipurpose visa to people of Indian origin. It does not confer political rights, but those with this visa enjoy parity with NRIs in economic, financial, and educational benefits such as the acquisition of property (with exceptions), admission to educational institutions, and eligibility for certain housing schemes.

The largest number of immigrants in Germany were from Ukraine, as of 2023. The top three origin countries were rounded up by Romania and Turkey. Immigrants are defined as having left a country, which may be their home country, to permanently reside in another. Upon arriving, immigrants do not hold the citizenship of the country they move to. Immigration in the EU All three aforementioned countries are members of the European Union, which means their citizens have freedom of movement between EU member states. In practice, this means that citizens of any EU member country may relocate between them to live and work there. Unrestricted by visas or residence permits, the search for university courses, jobs, retirement options, and places to live seems to be defined by an enormous amount of choice. However, even in this freedom of movement scheme, immigration may be hampered by bureaucratic hurdles or financial challenges. Prosperity with a question mark While Germany continues to be an attractive destination for foreigners both in and outside the European Union, as well as asylum applicants, it remains to be seen how current events might influence these patterns, whether the number of immigrants arriving from certain countries will shift. Europe’s largest economy is suffering. Climbing inflation levels in the last few months, as well as remaining difficulties from the ongoing coronavirus (COVID-19) pandemic are affecting global economic development. Ultimately, future immigrants may face the fact of moving from one struggling economy to another.

Sikhism is a religion that originated on the Indian subcontinent during the fifteenth century. Sikhs follow the teachings of 'gurus', who descend from the first guru Guru Naruk who established the faith. Followers of Sikhism are monotheists, believing in only one god, and other core beliefs include the need to meditate, the importance of community and communal living, and the need to serve humanity selflessly (or 'seva'). Sikhism and the British Empire In total, there are around 26 million Sikhs worldwide, and over 24 million of these live in India. Outside of India, the largest Sikh populations are mostly found in former territories of the British Empire - the UK and Canada both have Sikh populations of over half a million people. Migration from India to other parts of the British Empire was high in the 19th century, due to the labor demands of relatively newer colonies, as well as those where slavery had been abolished. These countries also remain popular destinations for Sikh migrants today, as many are highly trained and English-speaking. Other regions with significant Sikh populations Italy also has a sizeable Sikh population, as many migrated there after serving there in the British Army during WWI, and they are now heavily represented in Italy's dairy industry. The Sikh population of Saudi Arabia is also reflective of the fact that the largest Indian diaspora in the world can now be found in the Middle East - this is due to the labor demands of the fossil fuel industries and their associated secondary industries, although a large share of Indians in this part of the world are there on a temporary basis.

As of October 2024, the United States had nearly 413,400 Japanese citizens, making it the country with the highest number of Japanese residents outside of Japan itself. The United States counted around four times as many Japanese citizens as second-placed Australia.  Japanese immigrants in the United States Lately, there has been an increase in the migration of Japanese individuals, especially to the United States, which has the largest immigrant population worldwide. This surge in Japanese migration to the United States can largely be attributed to the substantial presence of Japanese companies with offices in the country, which ranks among the highest globally. Consequently, many Japanese nationals choose to relocate to the United States in pursuit of employment opportunities offered by these companies.  Status of immigrants in Japan The total number of foreign residents in Japan has been rising lately, with Tokyo having the highest number of foreign nationals registered among 47 prefectures. The main nationality of foreign residents living in Japan are people from the Asia region: China, Vietnam, and South Korea. The increasing number of foreign nationals working in Japan is indicative of the growing interest in job opportunities within the country.

The two countries with the greatest shares of the world's Jewish population are the United States and Israel. The United States had been a hub of Jewish immigration since the nineteenth century, as Jewish people sought to escape persecution in Europe by emigrating across the Atlantic. The Jewish population in the U.S. is largely congregated in major urban areas, such as New York, Los Angeles, and Chicago, with the New York metropolitan area being the city with the second largest Jewish population worldwide, after Tel Aviv, Israel. Israel is the world's only officially Jewish state, having been founded in 1948 following the first Arab-Israeli War. While Jews had been emigrating to the holy lands since the nineteenth century, when they were controlled by the Ottoman Empire, immigration increased rapidly following the establishment of the state of Israel. Jewish communities in Eastern Europe who had survived the Holocaust saw Israel as a haven from persecution, while the state encouraged immigration from Jewish communities in other regions, notably the Middle East & North Africa. Smaller Jewish communities remain in Europe in countries such as France, the UK, and Germany, and in other countries which were hotspots for Jewish migration in the twentieth century, such as Canada and Argentina.

With nearly 49,000 living in Denmark as of January 1, 2024, most immigrants were from Poland. The second and third largest groups of immigrants were from Ukraine and Romania, amounting to roughly 41,000 and 40,000 people, respectively. Tightening immigration policies Like many European countries, Denmark experienced a heightened influx of immigrants in 2015. In the wake of the refugee situation, however, the number of immigrants, notably asylum seekers, declined in part due to sharpened immigration policies. In 2015, over 21,000 refugees applied for asylum in Denmark, whereas applications fell below 5,000 in 2022. Residence permits Among the different types of residence permits, permits granted based on asylum were the least delivered type of permit. Only 1,400 people were granted asylum in Denmark in 2022. The highest number of asylum seekers came from Ukraine, even when excluding Ukrainians arriving via the temporary protection act. In 2022, Denmark registered around 2,000 applications from Ukrainians.

In 2023, it was estimated that more than four million Brazilians were living outside Brazil. The United States had the largest community, with over two million Brazilian citizens. Portugal was the second country with the largest Brazilian community, namely 513,000 citizens. Brazilians abroad The Brazilian community sought economic opportunities in the United States in the 1980s, leading to the establishment of communities in New York and Boston. Facilitated by the common language and Portugal's favorable laws for the Community of Portuguese-speaking countries, Lisbon became the most popular destination in Europe. This city harbors more than 77,000 Brazilians, with women making up the majority of these. Immigration in Brazil Although more than four million Brazilians live outside of Brazil, the country has had a positive migration rate since 2010, meaning that more people are arriving than leaving. One factor contributing to this is the current humanitarian crisis in Venezuela, which has increased the number of refugees arriving in Brazil each year.

Argentina has the largest Italian population outside of Italy, with around 1.17 million Italians residing in the South American country as of 2023. This community represented almost one fifth of all citizens residing outside the Republic, seven million. Germany hosted the second-largest community, with about 900,000 Italians, while in Brazil lived around 790,000 people with Italian citizenship. In total, three million Italians resided in the Americas, whereas 3.5 million in other European countries. In the nineteenth and twentieth centuries, Argentina was one of the main destinations for Italian emigrants, in particular in the early 1900s. Increasing tendency to emigrate  Between 2006 and 2020, the number of Italians living abroad constantly increased. As of 2020, over five million Italians lived outside their homeland. Data related to the educational level of the emigrated population show that one third of the academics decided to leave the country. In 2017, 32.5 percent of Italians holding a university degree did not reside in Italy. Better jobs and lower taxes  When asked about the reasons why leaving their country, the opportunity to pay lower taxes and have better jobs played an important role. Indeed, about 43 percent of Italians declared to be ready to leave Italy for a place where taxes were lower. In addition, roughly 37 percent could leave Italy for better working chances.

As of 2023, more than 6.1 million Italians lived abroad. In particular, the largest community of migrants was in Argentina, as this country was hosting around 953,000 Italian citizens. Two European states followed in the ranking, Germany and Switzerland, while Brazil had the fourth-largest Italian emigrated population. In total, about 3.32 million emigrants lived in other European countries, while 2.5 million resided in the Americas.

Out of a total of nearly 11.2 million Mexican emigrants around the world in 2020, almost 10.9 million relocated to the United States. The second most popular country of destination for emigrants of this Latin American nation was Canada followed by Spain. In 2019, nearly 47 percent of Mexican emigrants living abroad were women.

In the Middle Ages, it is believed the largest Jewish populations in the world were found in Asia, particularly across the Middle East. Of the estimated total Jewish population of 1.2 million people, over 80 percent are thought to have lived in Asia, while 13 percent lived in Europe, and the remaining six precent lived in (North) Africa. The largest populations were found on the Arabian peninsula, as well as Iran and Iraq, while the Near East (here referring to the Levant region) had a much smaller population, despite being the spiritual homeland of the Jewish people.

These figures are based on the records of Benjamin of Tudela, a Jewish traveller from the Middle Ages who provided one of the most comprehensive collections of population statistics from the period. Benjamin's writings not only recorded the number of Jews living across this part of the world, but also gave an insight into societal structures and the ordinary daily lives within Jewish communities in the medieval period. The source providing these figures, however, has adjusted some of the statistics to account for known populations that were missing from Benjamin of Tudela's records, especially in Europe and Asia.

In 2024, Turkey was the country that hosted the highest amount of Syrian refugees, amounting up to 3.1 million refugees. Lebanon was second, hosting 775,000 Syrian refugees. The data refers to the total number of Syrian refugees in a given country, not considering the date of their application for asylum or the date of their flight.

The United States reported the highest number of emigrants from the Philippines in 2022, with about 18.6 thousand Filipinos choosing to live there permanently. In comparison, Spain had 269 Filipino emigrants that year.An emigrant is a person who has left their own country to live permanently in another.

Over 1.2 million refugees from Ukraine due to the Russian invasion fled to Germany as of April 2025. Furthermore, the second-highest number was recorded in Russia. In total, around 6.4 million Ukrainian refugees were registered across Europe and 6.9 million worldwide as of April 2025. Most of them fled the country by crossing the border with Poland. Ukrainian refugees in Germany As of January 2025, over 1.2 million refugees from Ukraine were recorded in Germany. The first increases in the number of Ukrainian refugees were registered in March and April 2022. At the end of January 2023, over one million refugees were officially counted by the authorities. Germany had the highest monthly financial allowance for Ukrainians who fled the war compared to other European countries as of June 2022. Temporary protection for Ukrainian refugees in the EU European Union (EU) members implemented the Temporary Protection Directive (TPD), which guaranteed access to accommodation, welfare, and healthcare to refugees from Ukraine. People fleeing the war had a right to a residence permit in the EU, enter the labor market, and enroll children in educational institutions. The protection is granted until March 4, 2026, but it can be extended in the future depending on the situation in the country.

The most frequently chosen country for emigration by Romanians in 2022 was Germany, with a share of about 22 percent of the total number of emigrants. Italy ranked second, being chosen by roughly 14 percent of Romanian emigrants.

The largest number of Russians living abroad was recorded in Europe, measuring at nearly 6.2 million people in 2020. Furthermore, over four million Russians resided in Asian countries. Northern America was a residence of nearly 482 thousand people who were born in Russia.

In 2011, 87.2 percent of the total population of the United Kingdom were white British. A positive net migration in recent years combined with the resultant international relationships following the wide-reaching former British Empire has contributed to an increasingly diverse population.

Varied ethnic backgrounds

Black British citizens, with African and/or African-Caribbean ancestry, are the largest ethnic minority population, at three percent of the total population. Indian Britons are one of the largest overseas communities of the Indian diaspora and make up 2.3 percent of the total UK population. Pakistani British citizens, who make up almost two percent of the UK population, have one of the highest levels of home ownership in Britain.

Racism in the United Kingdom

Though it has decreased in comparison to the previous century, the UK has seen an increase in racial prejudice during the first decade and a half of this century. Racism and discrimination continues to be part of daily life for Britain’s ethnic minorities, especially in terms of work, housing, and health issues. Moreover, the number of hate crimes motivated by race reported since 2012 has increased, and in 2017/18, there were 3,368 recorded offenses of racially or religiously aggravated assault with injury, almost a thousand more than in 2013/14.

This graph shows the population distribution of Chinese people living abroad in 2013 and 2023, by continent, according to official Taiwanese sources. By the end of 2023, around 2.44 million people of Chinese birth or descent who were living overseas were living in Europe. The figures of the source are in most cases higher - in some cases considerably higher - than figures published by the UN, as not only first generation migrants are included, but also their descendants.
