At 9,833,520 km² the United States has the fourth-largest land area in the world, and its 50 states and federal district span enough longitude that the ordinary clock runs from UTC−4 to UTC−10, with the territories reaching −12, +10 and +11. The 2025 population estimate is 341,784,857. Washington, D.C. is the capital and New York the largest city, but neither stands in for the rest of it. Distance is the planning problem here, not choice: a trip works far better as one region covered properly than as anything resembling a national tour.
