In 2002 the Sudan Relief and Rehabilitation Association, the humanitarian wing of the
Sudan People's Liberation Movement, estimated that the population was 67,340, including internally displaced persons. The county's area is home to the
Ketebo,
Dongotono,
Imotong,
Logir,
Otuho,
Lango: Lokwa & Lorwama. The Lango tribe has two sub-tribes – the
Lango,
Lorwama. The Lango keep cattle and cultivate millet, melons, sweet potatoes, beans, bananas, tobacco. The Ketebo live in Bira which include Lotome, Nakoringole, Lofus, Ateda/ Madiel, Lorum, Napeyase, Longairo, Osisi, Toomodo, Okosio, Ofi, Lobila Tome, Kamulach, Kalabe, Narus Bokolore, Lorife, Lonyili, Irobi, Lojilingare, etc. while the Dongotona live in dense settlements, cultivate sorghum, groundnuts, simsim, telebun, and sweet potatoes, and keep large herds of cattle, sheep and goats. Cattle play a central role in social life, used in contracting marriages and performing rituals, and exchanged as gifts. The tribes have always indulged in cattle raiding, particularly during the dry season when the grass is short and cattle can be moved faster. There have always been conflicts between the tribes, notably in the
Kidepo valley, using the traditional weapons of spears and sticks. In the past, the number of lives lost was limited, and peace would soon be made through formal ceremonies. The people of the region live by subsistence agriculture, mostly growing sorghum and millet, and livestock raising. 90% of the agricultural work is undertaken by women using hand tools. Crops are generally rain-fed, with no irrigation, making them vulnerable to reduced rainfall or drought in either of the two growing seasons. Fishing, natural resource exploitation, mining and trade are practiced in a small way. The people live in extreme poverty with no rights of land tenure, and chronic insecurity. There is no infrastructure and no legal framework to make investment practical. ==Colonial era==
