New Delhi is the capital city of India. It is situated in the central north of the country on the banks of the Yamuna River about 160 kilometres south of the Himalayas and has a population of around 8 million. The government and administrative services are the chief employer, and services generally are the most important sector of the economy; the industrial sector is second, and the commercial sector is third. New Delhi is also a manufacturing centre with small and medium scale industries producing electronics and engineering goods, automobile parts, and electrical appliances. Traditional handicrafts, such as ivory carving, painting, brassware, and copperware, continue to be important, as are hand-loomed products and garments. Because of New Delhi's geographic location, all land routes from north western India to the eastern plain must pass through the city; five national highways and several railway lines converge there. The Indira Gandhi International Airport and the adjacent Palam domestic airport serve this important air-traffic centre.
