Overview
- Fundación Adecco projects 5.32 million retirements versus about 1.83 million young entrants by 2035, leaving only one new worker for every three who exit.
- Adecco estimates a deficit of roughly 3.5 million Social Security contributors in ten years unless the working‑age population expands.
- INE and Adecco scenarios foresee 4.5–4.6 million foreign arrivals between 2026 and 2035, about 80% of working age and 70% likely to seek jobs, with large regional inflows such as 700,000+ to Valencia and 631,000+ to Andalusia.
- Regional gaps are acute: Andalusia faces about 854,300 retirements vs 291,000 entrants; the Basque Country about 260,600 vs ~56,000; Valencia about 579,900 vs 208,260; Córdoba about 90,000 vs 24,371.
- Proposed responses emphasize recruiting foreign workers, activating senior talent, faster credential recognition, housing solutions, targeted training, and selective use of AI and automation to lift productivity.
