Notes:

Social security comprises the protection that a society provides to individuals and households to ensure access to medical care and guarantee income security, in particular in the event of old age, unemployment, illness, disability, work-related accidents, maternity or loss of a breadwinner (see https://www.ilo.org/global/standards/subjects-covered-by-international-labour-standards/social-security/lang--es/index.htm).

The indicator on Employed contributing to a pension system covers a part of social security by considering the contribution of the employed population to a pension system, which is an approximation to the probability of access to a future pension.
