Demographics of Kerala

Kerala is a state in south-western India. Most of Kerala's 34.8 million people (in 2011) are ethnically Malayalis (Malayalam speakers). Most of the Malayalam and English speaking Keralites derive their ancestry from Dravidian communities that settled in Kerala. Additional ancestries derive from millennia of trade links across the Arabian Sea, whereby people of Arab, Jewish, Syrian, Portuguese, English and other ethnicities settled in Kerala. Many of these immigrants intermarried with native Malayalam speakers resulting in formation of many Muslim and Christian groups in Kerala. Some Muslims and Christians thus take lineage from Middle Eastern and European settlers who mixed with native population.

Malayalam is Kerala's official language and is spoken by at least 97% of the people of Kerala; the next most common languages are English and Tamil which is spoken mainly by migrant workers from the neighbouring state of Tamil Nadu. Tulu and Kannada is spoken in northern parts of Kasaragod district, bordering Karnataka. In addition, Kerala is home to 321,000 indigenous tribal Adivasis (1.10% of the populace). Some 63% of tribals reside in the eastern districts of Wayanad (where 35.82% are tribals), Palakkad (1.02%), and Idukki (15.66%). These groups, including the Paniyars, Mooppans, Irulars, Kurumbars, and Mudugars, speak their own native languages. Cholanaikkan tribe in the Silent Valley National Park were contacted only in the 1970s and they are the most isolated tribe in the state.
