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.[24] It is estimated to have reached the 200 million mark in 1967, and the 300 million mark on October 17, 2006.[24][25] 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,[26] representing one-third of the population increase.[27] The U.S. population grew by 1.6 million from 2018 to 2019, with 38% of growth from immigration.[28] 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.[29]
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.[30]
Latino Americans accounted for 51.1% of the total national population growth between 2010 and 2020.[31] The Hispanic or Latino population increased from 50.5 million in 2010 to 62.1 million in 2020: a 23% increase and a numerical increase of more than 11.6 million.[31] Immigrants and their U.S.-born descendants are expected to provide most of the U.S. population gains in the decades ahead.[32]
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.[33][34]
As of 2022[update], births to White American mothers remain around 50% of the US total, reflecting a decline of 3% compared to 2021.[35] In the same time period, births to Asian American and Hispanic women increased by 2% and 6%, respectively.[36]
