Assam is a state in northeastern India, south of the eastern Himalayas along the Brahmaputra and Barak River valleys. Assam covers an area of 78,438 km. The state is bordered by Bhutan and Arunachal Pradesh to the north; Nagaland and Manipur to the east; Meghalaya, Tripura, Mizoram and Bangladesh to the south; and West Bengal to the west via the Siliguri Corridor, a 22 kilometres (14 mi) wide strip of land that connects the state to the rest of India. 

Assamese is the official and most commonly spoken language of the state, followed by Bengali, which is official in the Barak Valley and Bodo, which is co-official in Assam and official in Bodoland Territorial Region.

Assam is known for Assam tea and Assam silk. The state was the first site for oil drilling in Asia.[12] Assam is home to the one-horned Indian rhinoceros, along with the wild water buffalo, pygmy hog, tiger and various species of Asiatic birds, and provides one of the last wild habitats for the Asian elephant. 

The Assamese economy is aided by wildlife tourism to Kaziranga National Park and Manas National Park, which are World Heritage Sites. Dibru-Saikhowa National Park is famed for its feral horses. Sal tree forests are found in the state which, as a result of abundant rainfall, look green all year round. Assam receives more rainfall than most parts of India; this rain feeds the Brahmaputra River, whose tributaries and oxbow lakes provide the region with a hydro-geomorphic environment.

Assam’s economy is based on agriculture and oil. Assam produces more than half of India’s tea.The Assam-Arakan basin holds about a quarter of the country’s oil reserves, and produces about 12% of its total petroleum. According to the recent estimates, Assam’s per capita GDP is ₹6,157 at constant prices (1993–94) and ₹10,198 at current prices; almost 40% lower than that in India. According to the recent estimates, per capita income in Assam has reached ₹6756 (1993–94 constant prices) in 2004–05, which is still much lower than India’s.
