Federal government	Unitary government
The system has multiple hierarchy levels, with both the central authority and the states (or provinces) both being sovereign.	There is no hierarchy of sovereign powers.
The central or national rules override the state rules.	States have no authority to pass their own laws, and the central or national government can order the states to do anything.
There is a balance between the levels of government.	The federal government has a huge percentage of the power. Examples include Japan and Saudi Arabia.
Power and responsibilities are shared between national and local levels.
