Subnational entities are regions or divisions within a country that have their own local governments and administrative powers. These can include states, provinces, territories, or municipalities. For example, in the United States, each of the 50 states operates under its own government, with the ability to create laws and manage local affairs. These entities play a crucial role in governance by addressing local needs and issues more effectively than a central government might. They can also have varying degrees of autonomy, allowing them to make decisions on matters like education, transportation, and public safety, tailored to their specific communities.
