The public sector constitutes the portion of the economy that is controlled by the government, including federal, state, and local governments, government-owned corporations, and quasi-autonomous non-governmental organizations. This segment of the economy plays a crucial role in providing essential services and maintaining infrastructure, ensuring the well-being and development of a nation.
Historical Context
The concept of the public sector has evolved significantly over centuries. In ancient civilizations like Rome and Greece, the state played a pivotal role in managing public works and providing services such as road construction, water supply, and public baths. The modern public sector took shape during the industrial revolution when the need for regulation, public welfare, and infrastructure grew exponentially.

- Industrial Revolution (18th Century): Rapid expansion of public sector services to support urbanization.
- Post-World War II: Growth of welfare states in Europe, with extensive government control over industries and public services.
