More than 40 languages are spoken by the ethnic groups of the entire region. The Ossetians, Kabards, Circassians, and Dagestanis are the major groups in North Caucasia. The Armenians, Georgians, and Azeris are the largest groups in Transcaucasia.
The Kura and Rion river valleys have traditionally been the main thoroughfares of the Caucasus. Now the Rostov-Makhachkala-Bakı RR links North Caucasia with Transcaucasia, and there is a line connecting Rostov-na-Donu and Armavir with the port of Batumi, beyond the Caucasus. In Transcaucasia the main line cuts through the center of the region from Bakı, Tbilisi, and Kutaisi, and there are lines along the Turkish border and the Caspian Sea.
Oil has been the major product in the Caucasus, with fields at Bakı, Grozny, and Maykop. There is an oil pipeline from Bakı, on the Caspian, through Tbilisi to Batumi, on the Black Sea, and pipelines from the fields at Grozny to the port of Makhachkala and to Rostov-na-Donu. Iron and steel are produced at Rustavi from the ores of Azerbaijan. Manganese is mined at Chiatura, and there are ferromanganese plants at Zestafoni. Power for these industries is produced at several large hydroelectric stations, notably at Kura.
On the mountain slopes, which are covered by pine and deciduous trees, there is stock raising. In the valleys, citrus fruits, tea, cotton, grain, and livestock are raised. Along the Black Sea coast between Anapa and Sochi there are many resorts and summer homes. Pyatigorsk and Kislovodsk are notable among the health and mineral resorts in North Caucasia.
