Document 2: Anglo-Indian: The term Anglo-Indians can refer to at least two groups of people: those with mixed Indian and British Isles ancestry, and people of British descent born or living in the Indian subcontinent. The latter sense is now mainly historical, but confusions can arise. The Oxford Dictionary, for example, gives three possibilities: "Of mixed British and Indian parentage, of Indian descent but born or living in Britain, or (chiefly historical) of British descent or birth but living or having lived long in India". People fitting the middle definition are more usually known as British Asian or British Indian. This article focuses primarily on the modern definition, a distinct minority community of mixed Eurasian ancestry, whose native language is English.

Document 15: Demographics of Kerala: Kerala is a state in south-western India. Most of Kerala's 33.3 million people (in 2011) are of Malayali (Malayalam language speaking) ethnicity. Most of the Malayalam and English speaking Keralites derive their ancestry from Dravidian and Aryan communities that settled in Kerala and intermixed with each other and existing populations. Additional ancestries derive from several centuries of contact with non-Indian lands, whereby people of Arab, Jewish, and other ethnicities settled in Kerala. Many of these immigrants intermarried with native Malayalam speakers. A tiny amount of Muslims thus take lineage from Arab settlers mixed with local population.
