US population

How it's calculated. Official resident population on July 1, 2025 (Vintage 2025): 341,784,857. Projected forward at Census population clock's stated rate (0.030359/s ≈ 958,051/yr). For reference, V2025's own Jul 2024→Jul 2025 change was 1,781,060 (net international migration 1,262,202); Census's current clock assumes slower growth, mainly lower net migration. The live clock level is used only as a cross-check.
