Defining government as an academic study requires multiple descriptions. Depending on what type of education is being taught (middle school, high school, undergraduate, graduate school, etc), the subject and content being taught will vary significantly. However, regardless of where or what is being taught, the academic field of study will always include how a country/state governs its citizens, manages the finances, works for the people, looks to grow, enforces the law, provides a foundation for businesses, controls borders, elects officials, settle disputes, and many more actions.
Whether the study of government looks at the political side of things (such as electing mayors, governors, the president, etc.), or looks at the action the government takes (spending tax money, providing healthcare, etc.), every individual needs to know the importance and role the government plays within a country and community.
