Although Kenya is the most industrially developed country in East Africa, manufacturing still accounts for only 14 percent of gross domestic product (GDP). The industry and manufacturing sectors have become increasingly important to the Kenyan economy, and has been reflected by an increasing GDP per capita. Industrial activity, concentrated around the three largest urban centres, Nairobi, Mombasa, and Kisumu, is dominated by food-processing industries such as grain milling, beer production, and sugarcane crushing, and the fabrication of consumer goods, e.g., vehicles from kits. Kenya also has an oil refinery that processes imported crude petroleum into petroleum products, mainly for the domestic market. In addition, a substantial and expanding informal sector engages in small-scale manufacturing of household goods, motor-vehicle parts, and farm implements.
