It is an important market town and transport hub and the 2001 census had a population of 44,663. The town is the historic center of the small pre-colonial Hausa state of Konni. The name is Hausa language for "Walled Town of Konni", and many Hausa towns (such as Zinder) designate the old citadel neighborhood the "Birni".
