- The multiracial population in the U.S. grew by 276% between 2010 and 2020.
- In the 2020 Census, 10.2% of the population self-identified as multiracial.

Multiracial Americans, also known as mixed-race Americans, are individuals who possess mixed ancestry from two or more races. This demographic group includes people who may identify with a single group culturally and socially, though their genetic ancestry is diverse. In the 2020 United States census, 33.8 million individuals, or 10.2% of the population, self-identified as multiracial, marking a significant increase in the visibility of this identity.

Demographic Growth and Census Trends
The multiracial population has seen a dramatic rise, increasing by 276% between 2010 and 2020. This growth was driven largely by Hispanic or Latino Americans identifying as multiracial, with this group increasing from 3 million in 2010 to over 20 million in 2020. Most multiracial Hispanics identified as white and "some other race" in combination.
While natural growth has occurred over the last few decades, the sharp rise seen in the 2020 census is attributed primarily to changes in the Census Bureau's methodology regarding write-in ancestry responses, rather than purely cultural or demographic shifts.
Historical Context and Social Evolution
Historically, racial systems and the impact of admixture between white European colonists and Native Americans often led individuals to be classified by only one ethnicity. Prior to the mid-20th century, many people hid their multiracial heritage due to racial discrimination against minorities.
Following a period of formal racial segregation and bans on interracial marriage, social conditions have shifted. More people are now openly forming interracial unions, and the social advantage of "passing" as white has diminished. Since the 1980s, a growing multiracial identity movement has emerged, allowing more Americans to acknowledge their mixed racial origins.
The 2000 Census Milestone
The 2000 census was a pivotal moment, as it was the first time residents were allowed to check more than one ethno-racial identity. This shift in policy reflected the growing insistence of Americans to be recognized as multiracial.
Prominent Examples and Diverse Groups
In 2008, Barack Obama, of Luo (Kenyan) and Scottish lineage, became the first biracial President of the United States. Multiracial groups in the U.S. include African Americans, Asian Americans, Hispanic Americans, Latino Americans, Métis Americans, Louisiana Creoles, Hapas, Melungeons, and European Americans, as well as many citizens of federally recognized Native American tribes.
History of Mixed-Race Ancestry in America
The American people are largely multi-ethnic descendants of various immigrant groups. Processes of creolization, assimilation, and integration have continued throughout history. The Civil Rights Movement and the social movements of the mid-twentieth century were crucial in achieving social justice and equal enforcement of civil rights for all ethnicities.
In the early colonial years, interracial relationships and marriages were common. However, the hardening of slavery as a racial caste associated with people of African descent led to the creation of laws such as partus sequitur ventrem, which dictated that children's social status followed that of the mother. This system was designed to increase the ability of white men to exploit slave women without responsibility for their children.
