The United States had an estimated population of 332,410,303 in 2021 according to United Nations data. According to the U.S. Census Bureau, the United States had an estimated population of 328,239,523 in 2019 (with an unofficial statistical adjustment to 329,484,123 as of ahead of the final 2020 Census). The United States is the third most populous country in the world, and current projections from the unofficial U.S. Population Clock show a total of just over 330 million residents. All these figures exclude the population of five self-governing U.S. territories (Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa and the Northern Mariana Islands) as well as several minor island possessions. The Census Bureau showed a population increase of 0.75% for the twelve-month period ending in July 2012. Though high by industrialized country standards, this is below the world average annual rate of 1.1%. The total fertility rate in the United States estimated for 2019 is 1.706 children per woman, which is below the replacement fertility rate of approximately 2.1.
