Understanding United States's Population

United States is one of the top 3 most populous country in the world, with an estimated population of 349,035,000 people as of today. This figure is an estimate — it starts from the most recent official count and advances second by second using United States's annual growth rate of 0.50%.

The population is growing steadily. At the current rate, United States adds or loses roughly 4,781 people per day. With a land area of 1,000,000 km², it is densely populated (349 people per km²).

The "Births Today" and "Deaths Today" figures are estimates based on annualized rates prorated to the time elapsed since midnight. The age and gender distribution reflects the most recent demographic profile available. For how these figures are computed, see our Methodology page.
