How quickly is Japan's population ageing? Show the share of people aged 65+ over time.

Unedited Atlas answer from October 5, 202617sgpt-6.1-sol

Nearly 30% of Japan’s population was aged 65+ in 2025—up from 5.7% in 1960. That is a rise of 24.3 percentage points, or more than fivefold. The chart shows the annual trend from 1960 through 2025, the latest year available in this series. (data.worldbank.org)

Ageing continues, but the pace has slowed recently:

  • 2010–2015: the share rose from 23.1% to 26.9%—about 0.77 percentage points per year.
  • 2015–2020: it reached 28.9%—about 0.40 points per year.
  • 2020–2025: it reached 30.0%—about 0.22 points per year.
    These rates are calculated from the World Bank series. (data.worldbank.org)

In short, roughly three in ten residents are now 65 or older, and their share is still increasing, though less rapidly than in the early 2010s. These are World Bank figures sourced from UN World Population Prospects; estimates can differ from Japan’s national statistics. (data.worldbank.org)
