Social security is a concept enshrined in Article 22 of the Universal Declaration of Human Rights, which states:
Everyone, as a member of society, has the right to social security and is entitled to realization, through national effort and international co-operation and in accordance with the organization and resources of each State, of the economic, social and cultural rights indispensable for his dignity and the free development of his personality.
In simple terms, the signatories agree that society in which a person lives should help them to develop and to make the most of all the advantages (culture, work, social welfare) which are offered to them in the country.
Social security may also refer to the action programs of government intended to promote the welfare of the population through assistance measures guaranteeing access to sufficient resources for food and shelter and to promote health and well-being for the population at large and potentially vulnerable segments such as children, the elderly, the sick and the unemployed. Services providing social security are often called social services.
Terminology in this area in the United States is somewhat different from in the rest of the English-speaking world. The general term for an action program in support of the well being of the population in the United States is welfare program and the general term for all such programs is simply welfare. In American society, the term welfare arguably has negative connotations. The term Social Security, in the United States, refers to a specific social insurance program for the retired and the disabled. Elsewhere the term is used in a much broader sense, referring to the economic security society offers when people are faced with certain risks. In its 1952 Social Security (Minimum Standards) Convention (nr. 102), the International Labour Organization (ILO) defined the traditional contingencies covered by social security as including:
People who cannot reach a guaranteed social minimum for other reasons may be eligible for social assistance (or welfare, in American English).
