United States Population Clock

United States records about 9,919 births and 8,422 deaths a day. That is a natural increase of roughly 1,497 people per day, or about 546,779 a year before migration is counted.

Net migration runs at about 1.23 million over the reported period, with more people arriving than leaving. That is equivalent to about 225% of its natural change.

If the current rate held indefinitely, United States would take roughly 133 years to double in size — a projection of today's rate, not a forecast.

Over the 9 years from 2016 to 2025, the population rose from 324.4 million to 341.8 million — a gain of 17.4 million, or 5.4%.

With about 37 people per square kilometre, United States is sparsely populated, well below the world average of 62. That ranks 88th of the 115 countries here. Its closest comparisons on density are Venezuela and Zimbabwe.

United States covers about 9,147,420 km² of land, which is what turns a population of 341.8 million into that density figure.

About 80.2% of people live in urban areas, making United States highly urbanised, above the world average of 57.8%. That works out to roughly 274.1 million town and city dwellers and 67.7 million living rurally.

United States has an ageing population: about 17.1% are under 15 and 18.4% are 65 or older. Over-65s now outnumber under-15s, which is the classic marker of a population that has finished its demographic transition.

The total fertility rate is about 1.63 births per woman, below the ~2.1 replacement level, so without net immigration the population would eventually decline. The world figure is about 2.19.

Life expectancy at birth is about 78.9 years, roughly 5.4 years above the global average of 73.5.
