Sorted by total, highest first. Every row is indexed to the last count complete before the first day in office ("from" marks a start that had to move because that count had no data, or because the period cut it); the prefecture is measured over the same months. Levels are per cent changes, rates are differences in %; "per year" compounds levels and divides rates. Tenures with under 12 months, or under three observations, are left out. US$ per person, purchasing power parity, current prices · Cabinet Office prefectural accounts apportioned by the OECD to the functional urban area, US dollars at purchasing power parity, current prices, calendar years dated at mid-year · metropolitan area (functional urban area) data · as of Sep 2026.
