Population during each mayor's tenure

17 mayors, ranked by how population changed from their first day in office, next to the prefecture over the same months. Politare shows what happened during a tenure; it does not claim the office-holder caused it.

No tenure qualifies with these filters.

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. thousands, metropolitan area · Census and estimates via the OECD metropolitan database (functional urban area), calendar years dated at mid-year · metropolitan area (functional urban area) data · as of Sep 2026.
