Kerala (/ˈkɛrələ/) is a state on the southwestern, Malabar Coast of India. It was formed on 1 November 1956 following the States Reorganisation Act by combining Malayalam-speaking regions. Spread over 38,863 km2(15,005 sq mi), Kerala is the twenty second largest Indian state by area. It is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea and Arabian Sea to the west. With 33,387,677 inhabitants as per the 2011 Census, Kerala is the thirteenth-largest Indian state by population. It is divided into 14 districts with the capital and largest city being Thiruvananthapuram. Malayalam is the most widely spoken language and is also the official language of the state.
The Chera Dynasty was the first prominent kingdom based in Kerala. The Ay kingdom in the deep south and the Ezhimala kingdom in the north formed the other kingdoms in the early years of the Common Era (CE or AD). The region had been a prominent spice exporter since 3000 BCE. The region’s prominence in trade was noted in the works of Pliny as well as the Periplus around 100 CE. In the 15th century, the spice trade attracted Portuguese traders to Kerala, and paved the way for European colonisation of India. At the time of Indian independence movement in the early 20th century, there were two major princely states in Kerala-Travancore State and the Kingdom of Cochin. They united to form the state of Thiru-Kochi in 1949. The Malabar region, in the northern part of Kerala had been a part of the Madras province of British India, which later became a part of the Madras State post-independence. After the States Reorganisation Act, 1956, the modern-day state of Kerala was formed by merging the Malabar district of Madras State (excluding Gudalur taluk of Nilgiris district, Topslip, the Attappadi Forest east of Anakatti), the state of Thiru-Kochi (excluding four southern taluks of Kanyakumari district, Shenkottai and Tenkasi taluks), and the taluk of Kasaragod (now Kasaragod District) in South Canara (Tulunad) which was a part of Madras State.
The economy of Kerala is the 12th-largest state economy in India with ₹7.73 lakh crore (US$110 billion) in gross domestic product and a per capita GDP of ₹163,000 (US$2,300). Kerala has the lowest positive population growth rate in India, 3.44%; the highest Human Development Index (HDI), 0.712 in 2015; the highest literacy rate, 93.91% in the 2011 census; the highest life expectancy, 77 years; and the highest sex ratio, 1,084 women per 1,000 men. The state has witnessed significant emigration, especially to Arab states of the Persian Gulf during the Gulf Boom of the 1970s and early 1980s, and its economy depends significantly on remittances from a large Malayali expatriate community. Hinduism is practised by more than half of the population, followed by Islam and Christianity. The culture is a synthesis of Aryan, Dravidian, Arab, and European cultures, developed over millennia, under influences from other parts of India and abroad.
The production of pepper and natural rubber contributes significantly to the total national output. In the agricultural sector, coconut, tea, coffee, cashew and spices are important. The state’s coastline extends for 595 kilometres (370 mi), and around 1.1 million people in the state are dependent on the fishery industry which contributes 3% to the state’s income. The state has the highest media exposure in India with newspapers publishing in nine languages, mainly English and Malayalam. Kerala is one of the prominent tourist destinations of India, with backwaters, hill stations, beaches, Ayurvedic tourism and tropical greenery as its major attractions.
