Kerala is a state in south-western India. Most of Kerala's 34.8 million people (in 2011) are ethnically Malayalis (Malayalam speakers). People of Kerala trace their origins to Dravidians and Aryans. Kerala people have mixed ancestry. 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 language are English. Tamil which is spoken mainly in the bordering districts of Kerala with Tamilnadu, especially Idukki and Palakkad districts.Tulu and Kannada is spoken in northern parts of Kasaragod district, bordering Karnataka.

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.

However, Kerala's population growth rate is far lower than the national average, although Kerala's population more than doubled between 1951 and 1991 – adding 15.6 million people to reach a total of 29.1 million residents in 1991 – the population stood at 31.8 million by 2001 and 33.3 million in 2011.

Features

Social development

Kerala ranks highest in India with respect to social development indices such as elimination of poverty, primary education and healthcare. This resulted from significant efforts begun in 1911 by the erstwhile Princely states of Cochin and Travancore to boost healthcare and education among the people. This central focus – deemed unusual in India – was then maintained after Kerala's post-independence inauguration as a state. Thus, Kerala has the highest literacy rate in India of 93.91% (2011); and life expectancy is now the highest in India. The suicide rates in Kerala are the highest in India. As per the 2011 census, Kerala and Puducherry are the only domiciles in India with a female-to-male ratio higher than 0.99. The ratio for Kerala is 1.084 – 1084 females per 1000 males – while the national figure is 0.940. It is also one of the states in India to have sub-replacement fertility. UNICEF and the World Health Organization (WHO) designated Kerala as the world's first "baby-friendly state" via its "Baby Friendly Hospital Initiative". The state is also known for Ayurveda, a traditional system of medicine – this traditional expertise is currently drawing increasing numbers of medical tourists. However, drawbacks to this situation includes the population's steady ageing – indeed, 11.2% of Keralites are age 60 or over. Kerala's unusual socioeconomic and demographic situation was summarised by author and environmentalist Bill McKibben:

Diversity

There are more than 2,500,000 migrants living in Kerala, mostly from Assam and West Bengal, constituting more than 8% of the population. There are also migrants from Bihar, Jharkhand, Chhattisgarh, Orissa, and the North East.
