Old-age dependency: structural level shift

The claim

Old-age dependency ratio (65+ per 100 aged 15-64), July 1: level shift detected around 2014

A two-segment mean-shift scan over the last 40 years places the largest level shift in old-age dependency ratio (65+ per 100 aged 15-64), july 1 around 2014: mean 18.35 before vs 26.58 after (shift = 4.4× pooled variability). The detector locates the shift; it does not attribute a cause.

Method

Deterministic two-segment mean-shift scan; break where |Δmean|/pooled sd ≥ 1.5 with ≥8 periods per segment.
