In public policy, a living wage is the minimum hourly income necessary for a worker to meet basic needs (for an extended period of time or for a lifetime). These needs include shelter (housing) and other incidentals such as clothing and nutrition. In some nations such as the United Kingdom and Switzerland, this standard generally means that a person working forty hours a week, with no additional income, should be able to afford a specified quality or quantity of housing, food, utilities, transport, health care, and recreation. In addition to this definition, living wage activists further define "living wage" as the wage equivalent to the poverty line for a family of four.
The living wage differs from the minimum wage in that the latter is set by law and can fail to meet the requirements of a living wage - or is so low that borrowing or application for top-up benefits is necessary. It differs somewhat from basic needs in that the basic needs model usually measures a minimum level of consumption, without regard for the source of the income.
