What the Data Shows
The share of Taiwan’s registered population aged 65 or older rose from 19.18% in 2024 to 20.06% in 2025. That was an increase of 0.88 percentage points in one year. The 2025 value moved 0.06 points above the 20% threshold used in the assigned super-aged framing. Each percentage uses the matching year-end registered-population denominator.

Data notes & caveats
The 20% threshold is used only to describe the age-65-plus share; each year uses its matching registered-population denominator.
Methodology
Compares the two official observations for 2024–2025; support changes use the same source-backed values without altering the published observations.
Source consistency notes
All primary values use the same Taiwan Ministry of the Interior household-registration source family and matching period basis.
