"A population of people", a "sovereign government which determines how a group of people is ruled" and "territory with set borders" are the factors that define a state.
Explanation:
A state, to be recognized as a state, has to fulfill certain criteria. These are related to the people, the sovereignty of the region, specified territory borders and the government in the region.
The people in the region with a common set of beliefs including one that of regional unity and integrity, make up a population.
This population resides within a certain territory with specified borders and is ruled by a sovereign government. Such a setting can be recognized as a state.
