Which system of government is not defined by a geographic distribution of power?

Democracy, is the right answer.

Explanation:

In the context of politics, "Democracy" refers to who holds power in the process the nation is administered, not where the power is allocated. Democracy is the kind of government which is ruled by people through the means of voting and civic participation. However, a democratic nation can decide where to place arrangements of power within the administration. On the other hand, in the unitary system, all the power rely in one place, for instance, at the central or national level. In a confederate system, the power is distributed at the provincial or state level. Similarly, in a  federal system, the power is distributed between governments at the national level and the state level.
