The Office of the Secretary of State for Social Security was created in October 1978, a few months before the approval of the Constitution.

[2] Until then, there were lower-level bodies such as the Undersecretariat for Social Security, and the government of that time wanted to give greater importance to this system by creating this position.

[3] In 1981, all the economic, budgetary, inspection and management control competencies of all the managing agencies and common services of the Social Security were transferred to it through the incorporation into its structure of the Office of the Comptroller General of the Social Security.

[7] The Social Security Information Technology Department has been under the responsibility of the Secretary of State since 2004.

This department assumed all the powers and bodies of the Ministry of Labour relating social security and migration affairs.
