Population during each president's tenure

Every president since 1991, ranked by how population changed from their first day in office. Politare shows what happened during a tenure; it does not claim the office-holder caused it.

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); 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. millions, mid-year estimate · World Bank (SP.POP.TOTL) from the UN's World Population Prospects, mid-year · Republic of the Congo data · as of Aug 2026.
