Punjab is a state in North India, forming part of the larger Punjab region. The state is bordered by the Indian states of Jammu and Kashmir to the north, Himachal Pradesh to the east, Haryana to the south and southeast, Rajasthan to the southwest, and the Pakistani province of Punjab to the west. The state capital is located in Chandigarh, a Union Territory and also the capital of the neighbouring state of Haryana. After the partition of India in 1947, the Punjab province of British India was divided between India and Pakistan. The Indian Punjab was divided in 1966 with the formation of the new states of Haryana and Himachal Pradesh alongside the current state of Punjab. Punjab is the only Sikh majority state in India. Agriculture is the largest industry in Punjab. Other major industries include the manufacturing of scientific instruments, agricultural goods, electrical goods, financial services, machine tools, textiles, sewing machines, sports goods, starch, tourism, fertilisers, bicycles, garments, and the processing of pine oil and sugar. Punjab also has the largest number of steel rolling mill plants in India, which are located in "Steel Town"—Mandi Gobindgarh in the Fatehgarh Sahib district. The word Punjab is a compound of the Persian words panj (five) and āb (waters). Thus Panjāb roughly means "the land of five rivers". The five rivers are the Sutlej, Beas, Ravi, Chenab and Jehlum (also spelled Jhelum). Traditionally, in English, there used to be a definite article before the name, i.e. "The Punjab". The name is also sometimes spelled as "Panjab". While the Greeks already referred to Punjab as Pentapotamia, an inland delta of five converging rivers, the name Punjab was given to the region by the Central Asian Turkic conquerors of India, and popularised by the Turco-Mongol Mughals. These five rivers of Punjab are Sutlej, Beas, Ravi, Chenab, and Jhelum. Only Sutlej, Ravi and Beas rivers flow in today's Punjab. The other two rivers are now in the state of Punjab, situated in Pakistan. The Punjab State is divided into three regions: Majha, Doaba and Malwa. Agriculture is the mainstay of Punjab's economy. Other major industries include manufacturing of scientific instruments, electrical goods, financial services, machine tools, textiles, sewing machines etc.. Punjab has made considerable economic progress after Independence despite the setback it suffered in 1947. It contributes nearly two thirds to the total production of food grains and a third of milk production in the country. It is the leading producer of wheat, thereby contributing to the national food security. The initiative of Green revolution (a major agricultural initiative) has been keenly taken forward by the people of Punjab. Even though Punjabis account for less than 2.5% of the Indian population, they are one of the most prosperous races in India. Their per capita income is twice the national average. Punjab is considered to have the best infrastructure in India; this includes road, rail, air and river transport links that are extensive throughout the region. Punjab also has the lowest poverty rate in India and has won the best state performance award, based on statistical data compiled by the Indian Government.
