Demographics
2005 estimates place Chad's population at 10,146,000; 25.8% live in urban areas and 74.8% in rural ones. The country's population is young: an estimated 47.3% is under 15. The birth rate is estimated at 42.35 births per 1,000 people, the mortality rate at 16.69. The life expectancy is 47.2 years.
Chad's population is unevenly distributed. Density is 0.1 /km2 (0.26 /sq mi) in the Saharan Borkou-Ennedi-Tibesti Region but 52.4 /km2 (136 /sq mi) in the Logone Occidental Region. In the capital, it is even higher. About half of the nation's population lives in the southern fifth of its territory, making this the most densely populated region.
Urban life is virtually restricted to the capital, whose population is mostly engaged in commerce. The other major towns are Sarh, Moundou, Abéché and Doba, which are less urbanised but are growing rapidly and joining the capital as decisive factors in economic growth. Since 2003, 230,000 Sudanese refugees have fled to eastern Chad from war-ridden Darfur. With the 172,000 Chadians displaced by the civil war in the east, this has generated increased tensions among the region's communities.
Polygamy is common, with 39% of women living in such unions. This is sanctioned by law, which automatically permits polygamy unless spouses specify that this is unacceptable upon marriage. Although violence against women is prohibited, domestic violence is common. Female genital mutilation is also prohibited, but the practice is widespread and deeply rooted in tradition; 45% of Chadian women undergo the procedure, with the highest rates among Arabs, Hadjarai, and Ouaddaians (90% or more). Lower percentages were reported among the Sara (38%) and the Toubou (2%). Women lack equal opportunities in education and training, making it difficult for them to compete for the relatively few formal-sector jobs. Although property and inheritance laws based on the French code do not discriminate against women, local leaders adjudicate most inheritance cases in favour of men, according to traditional practice.
Chad has more than 200 distinct ethnic groups, which create diverse social structures. The colonial administration and independent governments have attempted to impose a national society, but for most Chadians the local or regional society remains the most important influence outside the immediate family. Nevertheless, Chad's peoples may be classified according to the geographical region in which they live. In the south live sedentary people such as the Sara, the nation's main ethnic group, whose essential social unit is the lineage. In the Sahel sedentary peoples live side-by-side with nomadic ones, such as the Arabs, the country's second major ethnic group. The north is inhabited by nomads, mostly Toubous. The nation's official business languages are French and Arabic, but over 100 languages and dialects are spoken. Due to the important role played by itinerant Arab traders and settled merchants in local communities, Chadian Arabic has become a lingua franca.
