Definition — Retirees' mean standard of living as % of the whole population's (100 = parity): observed (Insee tax and social income surveys), then projected in the COR reference scenario (June 2026).

• Projections: reference scenario of the COR (Conseil d’orientation des retraites), annual report of June 2026 — central Insee demographic assumptions (fertility 1.45 from 2028, net migration +150,000 a year), hourly labour productivity +0.7 % a year, unemployment 7 % from 2040. It is a scenario, not a forecast: it is sensitive to the productivity, unemployment and net-migration assumptions. The headline is always the last observed year, never a projection.
