In a unitary system of government, the degree of centralization is high. This is because in a unitary system, power is concentrated at the national or central level, with little or no power devolved to subnational units such as regions or states. The central government makes most of the important decisions and controls the resources of the country, while the regional or local governments are subordinate and carry out the policies of the central government. Therefore, the degree of centralization is high in a unitary system of government.
