Bhojpuri is an Indo-Aryan language native to the Bhojpur-Purvanchal region of India and the Terai region of Nepal. It is chiefly spoken in western Bihar, eastern Uttar Pradesh and northwestern Jharkhand. It is an eastern Indo Aryan language and as of 2000 is spoken by about 5% of India's population. Bhojpuri is a descendant of Magadhi Prakrit and is closely related to Maithili, Magahi, Bangla, Odia, Assamese, etc. languages.
Indo-Caribbean or Indian-Caribbean people are Indian people in the Caribbean who are descendants of the Jahaji Indian indentured laborers brought by the British, Dutch, and French during the colonial era from the mid-19th century to the early 20th century.

South Asian ethnic groups are an ethnolinguistic grouping of the diverse populations of South Asia, including the nations of Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka. While Afghanistan is variously considered to be a part of both Central Asia and South Asia, Afghans are generally not included among South Asians.
Bihari is a demonym given to the inhabitants of the Indian state of Bihar. Bihari people can be separated into three main Indo-Aryan ethnolinguistic groups, Bhojpuris, Maithils and Magadhis. They are also further divided into a variety of hereditary caste groups. In Bihar today, the Bihari identity is seen as secondary to caste/clan, linguistic and religious identity but nonetheless is a subset of the larger Indian identity. Biharis can be found throughout India, and in the neighbouring countries of Nepal, Pakistan and Bangladesh. During the Partition of India in 1947, many Bihari Muslims migrated to East Bengal. Bihari people are also well represented in the Muhajir people of Pakistan because of Partition.
Bihari Muslims are adherents of Islam who identify linguistically, culturally, and genealogically as Biharis. They are geographically native to the region comprising the Bihar state of India, although there are significantly large communities of Bihari Muslims living elsewhere in the Indian subcontinent due to the Partition of British India in 1947, which prompted the community to migrate en masse from Bihar to East Pakistan.
Indo-Mauritians are Mauritians who trace their ethnic ancestry to the Republic of India or other parts of the Indian subcontinent in South Asia.
Stranded Pakistanis in Bangladesh are Urdu-speaking Muslim migrants with homelands in present-day Bihar who settled in East Pakistan following the partition of India in 1947.
Caribbean Hindustani is an Indo-Aryan language spoken by Indo-Caribbeans and the Indo-Caribbean diaspora. It is a koiné language mainly based on the Bhojpuri and Awadhi dialects. These Hindustani dialects were the most spoken dialects by the Indians who came as immigrants to the Caribbean from India as indentured laborers. It is closely related to Fiji Hindi and the Bhojpuri-Hindustani spoken in Mauritius and South Africa.
Fiji Hindi is an Indo-Aryan language spoken by Indo-Fijians. It is an Eastern Hindi and Bihari language, considered to be a koiné language based on Awadhi that has also been subject to considerable influence by Bhojpuri, other Eastern Hindi and Bihari dialects, and Standard Hindi-Urdu. It has also borrowed some vocabulary from English, Fijian, Tamil, Telugu, Bengali, Punjabi, Gujarati, and Malayalam. Many words unique to Fiji Hindi have been created to cater for the new environment that Indo-Fijians now live in. First-generation Indians in Fiji, who used the language as a lingua franca in Fiji, referred to it as Fiji Baat, "Fiji talk". It is closely related to Caribbean Hindustani and the Bhojpuri-Hindustani spoken in Mauritius and South Africa. It is largely mutually intellegible with the languages of Awadhi and Bhojpuri, as well as with the Bihari languages of Bihar, Uttar Pradesh, Jharkhand, Madhesh, Koshi and Lumbini, and the dialects of Eastern Hindi of Uttar Pradesh, Madhya Pradesh, Chhattisgarh and Lumbini, but differs in phonetics and vocabulary with Modern Standard Hindi and Urdu.
The Indian diaspora in Southeast Africa consists of approximately 3 million people of Indian origin. Some of this diaspora in Southeast Africa arrived in the 19th century from British India as indentured labourers, many of them to work on the Kenya–Uganda railway. Others had arrived earlier by sea as traders.
Anti-Bihari sentiment refers to discrimination against the migrant people of the State of Bihar. Bihar had slower economic growth than the rest of India in the 1990s which led to Biharis migrating to other parts of India in search of opportunities. Bihari migrant workers have been subject to a growing degree of hatred by the locals of those states because of their stereotyping as criminals, rapists and traitors. Moreover, the Biharis have been victimized due to the growing anti-Hindi imposition sentiment in non-Hindi states owing to the Central government agencies excluding regional languages in many national exams and services.
Bihari Mauritians are the descendants of mainly Bhojpuri and some Awadhi speaking migrants to Mauritius. A majority of Indo-Mauritians are of Bihari descent, and the majority of Mauritians are Indo-Mauritian. All but one Mauritian prime ministers have been of Bihari descent. The community includes a Hindu majority, followed by Muslims while a minority practices Christianity. About 60 percent of the 1.2 million population of Mauritius is of Indian origin, many them from Bihar, with Bhojpuri as their mother tongue.

Overseas Indians, officially Non-Resident Indians (NRIs) and People of Indian Origin (PIOs) are Indians who reside or originate outside of India.

The term "Muhajirs" refers to those Muslim migrants from India, who settled in urban Sindh. The Muhajir community also includes stranded Pakistanis in Bangladesh who migrated to Pakistan after 1971 following the secession of East Pakistan in the Bangladesh Liberation War.
Nowadays, no one could still claim his pure race status. Ethnic, social and linguistic differences become each day more and more present and marked all over the world. Time, history and continuous population intermingling across boundaries led to create cosmopolitan beings, that is to say world citizens who, in spite of their singularity, manage to bring themselves together in order to create a unique and single nation. Among the nations most affected by this cross-fertilization is notably found Mauritius. The social and linguistic diversity of this country makes it unique and contribute to its wealth. It arouses curiosity, urges us to deepen our knowledge on the subject and is, to this extent, worth being studied.
The Bhojpuri people or Bhojpuriyas are an Indo-Aryan ethnic group from the Indian subcontinent who speak the Bhojpuri-language and inhabit the Bhojpuri-Purvanchal region. This area is now divided between the western part of the Indian state of Bihar, the eastern part of the Indian state of Uttar Pradesh, northwestern Jharkhand, along with some neighbouring districts in the Madhya Pradesh and Madhesh of Nepal. A significant diaspora population of Bhojpuris can be found in Trinidad and Tobago, Netherlands, Guyana, Jamaica, Suriname, other parts of the Caribbean, Fiji, South Africa, and Mauritius.
The Bihari Muslim minority in Bangladesh were subject to persecution during and after the 1971 Bangladesh Liberation War, experiencing widespread discrimination. Biharis were ethnic Urdu-speakers and largely maintained a pro-Pakistani stance, supported the Pakistan Armed Forces and opposed the independence of Bangladesh and the Bengali language movement of the Bengali Muslims. Biharis faced reprisals from Mukti Bahini and militias resulting in an estimated death toll ranging from 1,000 to 150,000. Bihari representatives claim 500,000 Biharis were killed, while the Pakistani government's "white paper" and the US Consul estimated 64,000 - 66,000 deaths.
