Overview
- Spain counted 148 people aged 65+ per 100 under‑16s in 2025, up 5.7 points in a year and roughly 18% over five years, marking a new peak.
- Andalusia reached 128.6%—its highest level—after a five‑year jump of 23%, remaining among the relatively younger regions but accelerating faster than the national pace.
- Castilla y León climbed to 230.7% and ranks third oldest among communities, with Zamora at about 340% leading provincial ageing, far above the national average.
- Fundación Adecco highlights a severe replacement gap, estimating that for every three people who retire only one worker enters the labor market, alongside long-duration unemployment affecting 48.5% of jobseekers over 45.
- Proposals include mobilizing senior talent, activating inactive groups, targeted labor immigration, and deploying AI to lift productivity, as some demographers urge more nuanced metrics than a simple 65+ to under‑16 ratio.
