Welfare spending is a type of government support intended to ensure that members of a society can meet basic human needs such as food and shelter. Social security may either be synonymous with welfare, or refer specifically to social insurance programs which provide support only to those who have previously contributed (e.g. pensions), as opposed to social assistance programs which provide support on the basis of need alone (e.g. most disability benefits). The International Labour Organization defines social security as covering support for those in old age, support for the maintenance of children, medical treatment, parental and sick leave, unemployment and disability benefits, and support for sufferers of occupational injury.
More broadly, welfare may also encompass efforts to provide a basic level of well-being through subsidized social services such as healthcare, education, infrastructure, vocational training, and public housing. In a welfare state, the state assumes responsibility for the health, education, infrastructure and welfare of society, providing a range of social services such as those described.
