- 112 - Right to social security (art. 9) 26. Article 9 of the Covenant provides generally that States parties "recognize the right of everyone to social security", without specifying the type or level of protection to be guaranteed. However, the term "social security" implicitly covers all the risks involved in the loss of means of subsistence for reasons beyond a person’s control. 27. In accordance with article 9 of the Covenant and the provisions concerning implementation of the ILO social security conventions - Convention No. 102 (1952) concerning Social Security (Minimum Standards) and Convention No. 128 (1967) concerning Invalidity, Old-Age and Survivors’ Benefits - States parties must take appropriate measures to establish general regimes of compulsory old-age insurance, starting at a particular age, to be prescribed by national law. 28. In keeping with the recommendations contained in the two ILO Conventions mentioned above and with ILO Recommendation No. 162 concerning Older Workers, the Committee invites States parties to establish retirement age so that it is flexible, depending on the occupations performed and the working ability of elderly persons, with due regard to demographic, economic and social factors. 29. In order to give effect to the provisions of article 9 of the Covenant, States parties must guarantee the provision of survivors’ and orphans’ benefits on the death of the breadwinner who was covered by social security or receiving a pension. 30. Furthermore, as already observed in paragraphs 20 and 21 above, in order fully to implement the provisions of article 9 of the Covenant, States parties should, within the limits of available resources, provide non-contributory old-age benefits and other assistance for all older persons who, when reaching the age prescribed in national legislation, have not completed a qualifying period of contribution and are not entitled to an old-age pension or other social security benefits or assistance and have no other source of income. Protection of the family (art. 10) 31. In accordance with article 10, paragraph 1, of the Covenant and recommendations 25 and 29 of the International Plan of Action on Ageing, States parties should make all the necessary efforts to support, protect and strengthen the family and help it, in accordance with each society’s system of cultural values, to respond to the needs of its dependent ageing members. Recommendation 29 encourages Governments and non-governmental organizations to establish social services to support the whole family when there are elderly people at home and to implement measures especially for low-income families who wish to keep elderly people at home. This assistance should also be provided for persons living alone or elderly couples wishing to remain at home. Right to an adequate standard of living (art. 11) 32. Principle 1 of the United Nations Principles for Older Persons, which stands at the beginning of the section relating to the independence of older persons, provides that: "Older persons should have access to adequate food,
