🇺🇸United States population (2025)
United States's population is 341.8M as of 2025 — the total resident population, all ages and both sexes. That places United States 3 of 217 countries with recent data. The world figure for the same period is 8.2B. In 1960 the figure was 180.7M — up 89% since then. Headcount is the stock; growth is the flow. Fertility, mortality, and net migration all move the total, but age structure decides how many workers and retirees that stock contains. UN medium projections on this site are scenarios, not commitments. Open the population chart below for the full series, or the country profile for neighbouring indicators.
