In 1881 the population numbered 1,699,747 (males 825,887, females 873,860), of whom 1,468,977 were Hindus, 89,767 Mohammedans, and 140,946 Christians. Tinnevelli has twelve towns with over 10,000 inhabitants each, viz., TINNEVELLI (see below); Srivilliputur, 18,256; Palamcotta, 17,964; Tuticorin, 16,281; Kulase Kharapatnam, 14,972; Sivagiri, 13,632; Viravanallur, 12,318; Kajapalayam, 12,021; Tenkasi, 11,987; Kayalpatnam, 11,806; Kalladakiirchi, 10,936; and Sivakasi, 10,833. Out of the total area of 5381 square miles 1403 are uncultivable waste. In 1885-86 cereals, chiefly rice and spiked millet or kambu, the staple food of the district, occupied 842,741 acres, pulses 192,341, oil seeds 78,127, and cotton 206,717. The total area of forest is roughly estimated at 1500 square miles. Tuticorin is the only port of any importance. The chief exports are cotton, coffee, jaggery, chillies, &c.; sheep, horses, cattle, and poultry are also sent to Ceylon. There is a considerable inland trade with Travancore. The pearl fishery on the coast is now unimportant. Coastal navigation is dangerous. In 1885-86 the total revenue of the district was 365,744, of which the land-tax yielded 305,850.
The early history of Tinnevelli is mixed up with that of Madura and Travancore. Down to 1781 it is a confused tale of anarchy and bloodshed. In that year the nawab of Arcot assigned the revenues to the East India Company, whose officers then undertook the internal administration of affairs. Several risings subsequently took place, and in 1801 the whole Carnatic, including Tinnevelli, was ceded to the British. Tinnevelli is now the most Christian district of all India, both Roman Catholic and Protestant.
