A basic income is a proposed system of social security, that periodically provides each citizen with a sum of money that allows the receiver to participate in society with human dignity. Except for citizenship, a basic income is entirely unconditional. Furthermore, there is no means test; the richest as well as the poorest citizens would receive it. The U.S. Basic Income Guarantee Network emphasizes this absence of means testing in its precise definition, "The Basic Income Guarantee is an unconditional, government- insured guarantee that all citizens will have enough income to meet their basic needs."In everyday usage, the phrase basic income is often inaccurately conflated with means tested guaranteed minimum income alternatives such as citizen's dividend or a negative income tax. A basic income of any amount less than the social minimum is referred to as a partial basic income.Moreover, in contrast to income redistribution between nations themselves, the phrase basic income defines payments to individuals rather than households, groups, or nations, in order to provide for individual basic human needs.
