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.

As of May 2024, a total of 5.4 million Indian migrants were estimated to live in the United States of America, followed by over three million in the United Arab Emirates (UAE). India has over 35 million overseas Indians living across the world.

The United Arab Emirates (UAE) had over 3.5 million overseas Indians residing in the country as of May 2024. Saudi Arabia had the second-highest Indian population among other GCC countries. 25 percent of overseas Indians reside in GCC countries. GCC, or the Gulf Cooperation Council, is a group of six nations – Saudi Arabia, UAE, Oman, Kuwait, Qatar and Bahrain.

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.

Delhi had over 21 percent of the external migrant population, the highest among all states in India. Himachal Pradesh and Punjab followed it with over 8 percent share each.

As of 2024, Romanians were Italy's largest foreign population, with over one million Romanians living in Italy during the period considered. Albania and Morocco followed with 416,000 and 412,000 people, respectively. From a regional perspective, the Northern regions had the largest foreign population. Lombardy had some 1.1 million foreign residents, the largest in the country.

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.

In 2020/21 there were approximately 696,000 Polish nationals living in the United Kingdom, the highest non-British population at this time. Indian and Irish were the joint second-largest nationalities at approximately 370,000 people.

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.

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.

In 2021, there were approximately 357,000 Indian residents living in London, the most of any foreign nationality. Nigerian nationals numbered 142,000, and were the second most common nationality in this year.
