ljl at the median age in 2100 being 86 but apparently thats what UN projections have too if zero migration
Table

Year Population (millions) Median Age (years) Notes
2025 59.0 48.2 Current baseline
2035 52.5 57.5 Rapid aging as births collapse
2045 46.7 65.8 Approaches retirement age
2055 41.6 72.5 UN projects 34.6% over 65 by 2050
2065 37.0 78.0 Istat projects average age 50.8, median slightly higher
2075 32.9 82.0 Near life expectancy; aging slows
2085 29.3 84.5 Stabilizes around life expectancy
2095 26.1 85.5 Minimal further increase
2100 24.6 86.0* Upper limit assuming life expectancy ~85-87
The UN's "zero migration" scenario shows Italy at 28.4 million by 2100 , but even their models cap median age around 80-85 because:
Technical limit: You can't have half the population older than the maximum human lifespan
Survivorship effect: By age 85, only ~30% of a birth cohort survives; by 98, <5% survive
