Which term encompasses all levels of government and their associated authorities?

The term "Public Sector" is applicable as it refers to all levels of government—federal, state, and local—as well as the various authorities and agencies that operate within these levels. The public sector encompasses all entities that are owned and operated by the government, including their services and functions. This includes public schools, law enforcement, infrastructure projects, and various social services that aim to serve the community's interests.

The public sector is distinguished from the private sector, which consists of businesses and organizations that are owned and operated by private individuals or groups. Meanwhile, exclusive and residual powers refer to the specific authorities granted to different levels of government under a constitutional framework, rather than the broader concept of government as a whole. Understanding these distinctions helps clarify the role of government in the economy and society.
