What is the difference between federal and unitary?
How do countries decide which system to use?
That can depend on historical, cultural, and political factors, as well as the size and diversity of a country. For example, larger countries like the United States and India may opt for a federal system to ensure that different regions have a say in governance, while smaller countries with a more homogeneous population might prefer a unitary system for simplicity and efficiency.
