School attendance has increased substantially since Zambia’s independence in 1964. In 2000 some 1.6 million pupils were enrolled in primary schools, representing 82 percent of school-aged children. Only 28 percent of secondary school-aged children were enrolled. The University of Zambia (founded in 1965), at Lusaka, had about 10,500 students in the mid-1990s. The Livingstone Museum, at Livingstone, has a collection relating to the archaeology and natural history of southern Africa. The Institute for African Studies of the University of Zambia publishes studies relating to central Africa.
The wealth of Zambia is based largely on mining in the rich copper belt, and downturns in copper prices have severely damaging economic consequences. Some processing and manufacturing has been started since independence, and during the 1970s attempts were made to diversify agriculture and to make the country self-sufficient in food. In 1999 the national budget showed $599 million in revenue and $546 million in expenditure.
In 2005 some 4.9 million Zambians participated in the labor force. The principal labor organization is the Zambia Congress of Trade Unions, which has about 400,000 members. Civil servants and miners also have unions.
Some 70 percent of Zambia’s working population is engaged in agriculture, largely subsistence farming. Principal crops and the amount produced in metric tons in 2005 were corn, the staple grain (1,161,000); sugarcane (1.8 million); and cassava (0.9 million). Sunflower seeds, peanuts, sweet potatoes, and tobacco are also grown. Beef and dairy cattle are raised for domestic use. The agricultural sector remains underdeveloped and vulnerable to weather fluctuations, and food shortages have occurred.
The copper mines of Zambia are among the richest in the world. Although world copper prices collapsed in 1975, damaging the Zambian economy, in the early 1990s the country still received about half of its export earnings from copper. Output in 2004 was 426,900 metric tons. Zambia is also among the world’s largest producers of cobalt. Other minerals extracted were gold (150 kg/331 lb), silver (7 metric tons), and gem-quality emeralds. A diamond field was discovered in 1992.
