Universal basic income (UBI) is a social welfare proposal in which all citizens of a given population regularly receive a minimum income in the form of an unconditional transfer payment, i.e., without a means test or need to work, in which case it'd be called guaranteed minimum income. It would be received independently of any other income. If the level is sufficient to meet a person's basic needs (i.e., at or above the poverty line), it is sometimes called a full basic income; if it is less than that amount, it may be called a partial basic income.
