The public sector refers to the part of the economy that is controlled and operated by the government. It includes various services and organizations that aim to provide essential services to the public, such as education, healthcare, and public safety. Examples of public sector entities include public schools, hospitals, and police departments. Funding for the public sector primarily comes from taxes collected from individuals and businesses. This funding allows the government to maintain and improve infrastructure, support social programs, and ensure the well-being of its citizens. The public sector plays a crucial role in promoting social equity and providing services that may not be profitable for private companies.
