The informal sector or informal economy as defined by governments, scholars, banks, etc. is the part of an economy that is not taxed, monitored by any form of overnment, or included in any Gross National Product (GNP), unlike the formal economy. In developing countries, some 60% of the potential working population earns their living in the informal sector. They would define this economy or sector in other words: not in what it is not, but what it is: the only way to earn a living for people who are self-employed outside the formal economy and not on anyone's payroll. Most of them live and work in this sector not because it is their wish or choice, but because they have no chance to be hired by an employer from the formal sector except for a few hours or days, with no legal right to be hired again.In developed countries the informal sector is characterized by unreported employment. This is hidden from the state for tax, social security or labour law purposes but is legal in all other aspects.
