The private and the public sector are different sectors of the economy.
The private sector is usually composed of organizations that are privately owned (and not part of the government). It usually includes corporations (both profit and non-profit) and partnerships. For example, retail stores, credit unions, and local businesses will operate in the private sector.
The public sector is usually composed of organizations that are owned and operated by the government. For example, educational bodies, health care bodies, police and prison services, and local and central governmental bodies and their departments operate in the public sector.
In summary, public sector is run by the government but private sector is run by private individuals or companies.
