Federalism is a system of government in which power is shared between the central (federal) government and the constituent units, such as states or provinces. In Nigeria, one major constraint on the smooth operation of federalism is the lack of an acceptable revenue allocation formula. This refers to the issue of how revenue from natural resources and taxes is shared among the federal, state, and local governments. The current formula has been a source of contention and has led to conflicts between the federal and state governments, as well as between different regions of the country. This has affected the ability of the federal system to promote equitable development and good governance across the country.
