Gujarat (, Gujarati: [ˈɡudʒəɾɑt] (listen)) is a state along the western coast of India. Its coastline of about 1,600 km (990 mi) is the longest in the country, most of which lies on the Kathiawar peninsula. Gujarat is the fifth-largest Indian state by area, covering some 196,024 km2 (75,685 sq mi); and the ninth-most populous state, with a population of 60.4 million. It is bordered by Rajasthan to the northeast, Dadra and Nagar Haveli and Daman and Diu to the south, Maharashtra to the southeast, Madhya Pradesh to the east, and the Arabian Sea and the Pakistani province of Sindh to the west. Gujarat's capital city is Gandhinagar, while its largest city is Ahmedabad. The Gujaratis are indigenous to the state and their language, Gujarati, is the state's official language. The state encompasses 23 sites of the ancient Indus Valley civilisation (more than any other state). The most important sites are Lothal (the world's first dry dock), Dholavira (the fifth largest site), and Gola Dhoro (where 5 uncommon seals were found). Lothal is believed to have been one of the world's first seaports. Gujarat's coastal cities, chiefly Bharuch and Khambhat, served as ports and trading centres in the Maurya and Gupta empires, and during the succession of royal Saka dynasties in the Western Satraps era. Along with Bihar, Mizoram and Nagaland, Gujarat is one of four Indian states to prohibit the sale of alcohol. The Gir Forest National Park in Gujarat is home to the only wild population of the Asiatic lion in the world.The economy of Gujarat is the fourth-largest in India, with a gross state domestic product (GSDP) of ₹19.44 trillion (US$240 billion) and has the country's 10th-highest GSDP per capita of ₹243,761 (US$3,100). Gujarat ranks 21st among Indian states and union territories in human development index. The state traditionally has low unemployment and is widely considered one of the most industrially developed states of India and a manufacturing hub.
