An unconditional basic income (also called basic income, basic income guarantee, universal basic income, universal demogrant, or citizen’s income) is a form of social security system in which all citizens or residents of a country regularly receive an unconditional sum of money, either from a government or some other public institution, in addition to any income received from elsewhere.An unconditional income transfer of less than the poverty line is sometimes referred to as a "partial basic income".Basic income systems that are financed by the profits of publicly owned enterprises (often called Social dividend or Citizen's dividend) are major components in many proposed models of market socialism.
