Statistics on AVS and AI supplementary benefits (PC)

Supplementary benefits (SB) are borne jointly by the federal government and the cantons. They are paid to people drawing an AVS or AI pension, provided they reside in Switzerland and their legally recognised expenses exceed their income as taken into account, i.e. their income does not cover their minimum cost of living. SB are needs-based insurance benefits to which the recipients have a legal entitlement.
