Description
Shuhei Nomura and a broad team ask in 2026 why healthy life expectancy figures disagree across Japan. Three national metrics plus a global model estimate were compared for forty-seven prefectures from 2001 to 2019. Survey-based metrics rely on self-reported limits, while one national metric uses care insurance records. Panel math linked gaps to disease burden, risks, and social traits.
Survey metrics matched the global model well for men but weakly for women. The records-based metric matched well for both sexes across the span. Mental disorders and body weight helped explain survey-model gaps in men. Knowing what each metric misses helps leaders pick the right gauge.
