The U.S. population almost quadrupled during the 20th century – at a growth rate of about 1.3% a year – from about 76 million in 1900 to 281 million in 2000. It is estimated to have reached the 200 million mark in 1967, and the 300 million mark on October 17, 2006. Foreign-born immigration caused the U.S. population to continue its rapid increase, with the foreign-born population doubling from almost 20 million in 1990 to over 45 million in 2015, representing one-third of the population increase. The U.S. population grew by 1.6 million from 2018 to 2019, with 38% of growth from immigration. Population growth is fastest among minorities as a whole, and according to the Census Bureau's 2020 estimation, 50% of U.S. children under the age of 18 are members of ethnic minority groups. As of 2020, white people numbered 235,411,507 or 71% of the population, including people who identified as white in combination with another race. People who identified as white alone (including Hispanic whites) numbered 204,277,273 or 61.6% of the population and Non-Latino whites made up 57.8% of the country's population.
Latino Americans accounted for 51.1% of the total national population growth between 2010 and 2020, increasing from 50.5 million in 2010 to 62.1 million in 2020. The Hispanic or Latino population increased by 23% between 2010 and 2020, an increase of more than 11.6 million. Immigrants and their U.S.-born descendants are expected to provide most of the U.S. population gains in the decades ahead.
Asian Americans are the fastest growing racial group in America, with a growth rate of 35%. However, multi-racial Asian Americans are the fastest growing group in the country, with a growth rate of 55%, reflecting the increase of mixed-race marriages in the United States.
As of 2022, births to White American mothers remain around 50% of the US total, reflecting a decline of 3% compared to 2021. In the same time period, births to Asian American and Hispanic women increased by 2% and 6%, respectively.
