The American people are mostly multi-ethnic descendants of various culturally distinct immigrant groups, many of which have now developed nations. Some consider themselves multiracial, while acknowledging race as a social construct.
Creolization,
assimilation and
integration have been continuing processes. The
Civil Rights Movement and other social movements since the mid-twentieth century worked to achieve social justice and equal enforcement of civil rights under the constitution for all ethnicities. In the 2000s, less than 5% of the population identified as multiracial. In many instances, mixed racial ancestry is so far back in an individual's family history (for instance, before the Civil War or earlier), that it does not affect more recent ethnic and cultural identification. Interracial relationships, common-law marriages and marriages occurred since the earliest
colonial years, especially before
slavery hardened as a racial caste associated with people of
African descent in Colonial America. Several of the
Thirteen Colonies passed laws in the 17th century that gave children the social status of their mother, according to the principle of
partus sequitur ventrem, regardless of the father's race or citizenship. This overturned the precedent in
common law by which a man gave his status to his children – this had enabled communities to demand that fathers support their children, whether legitimate or not. The change increased white men's ability to use slave women sexually, as they had no responsibility for the children. As master as well as father of mixed-race children born into slavery, the men could use these people as servants or laborers or sell them as slaves. In some cases, white fathers provided for their multiracial children, paying or arranging for education or apprenticeships and freeing them, particularly during the two decades following the
Revolutionary War. (The practice of providing for the children was more common in
French and
Spanish colonies, where a class of free people of color developed who became educated and property owners.) Many other white fathers abandoned the mixed race children and their mothers to slavery. The researcher Paul Heinegg found that most families of free people of color in colonial times were founded from the unions of white women, whether free or indentured servants and African men, slave, indentured or free.
Anti-miscegenation laws were passed in most states during the 18th, 19th and early 20th centuries, but this did not prevent white slaveholders, their sons, or other powerful white men from taking slave women as concubines and having multiracial children with them. In California and the rest of the
American West, there were greater numbers of Latin American and Asian residents. These were prohibited from official relationships with whites. White legislators passed laws prohibiting marriage between
European and Asian Americans until the 1950s.
Early United States history Interracial relationships have had a long history in North America and the United States, beginning with the intermixing of European explorers and soldiers, who took native women as companions. After European settlement increased, traders and fur trappers often married or had unions with women of native tribes. In the 17th century, faced with a continuing, critical labor shortage, colonists primarily in the Chesapeake Bay Colony, imported Africans as laborers, sometimes as indentured servants and, increasingly, as slaves. African slaves were also imported into New York and other northern ports by European colonists. Some African slaves were freed by their masters during these early years. In the colonial years, while conditions were more fluid, white women, indentured servant or free, and African men, servant, slave or free, made unions. Because the women were free, their mixed-race children were born free; they and their descendants formed most of the families of
free people of color during the
colonial period in Virginia. The scholar Paul Heinegg found that eighty percent of the free people of color in North Carolina in censuses from 1790 to 1810 could be traced to families free in Virginia in colonial years. In 1789,
Olaudah Equiano, a former slave from modern-day
Nigeria who was enslaved in North America, published his autobiography. He advocated interracial marriage between whites and blacks. By the late eighteenth century, visitors to the Upper South noted the high proportion of mixed-race slaves, evidence of miscegenation by white men. In 1790, the first federal population census was taken in the United States. Enumerators were instructed to classify free residents as white or "other." Only the heads of households were identified by name in the federal census until 1850. Native Americans were included among "Other;" in later censuses, they were included as "
Free people of color" if they were not living on
Indian reservations. Slaves were counted separately from free persons in all the censuses until the Civil War and end of slavery. In later censuses, people of African descent were classified by appearance as
mulatto (which recognized visible European ancestry in addition to African) or black. After the
American Revolutionary War, the number and proportion of free people of color increased markedly in the North and the South as slaves were freed. Most northern states abolished slavery, sometimes, like New York, in programs of gradual emancipation that took more than two decades to be completed. The last slaves in New York were not freed until 1827. In connection with the
Second Great Awakening, Quaker and Methodist preachers in the South urged slaveholders to free their slaves. Revolutionary ideals led many men to free their slaves, some by deed and others by will, so that from 1782 to 1810, the percentage of
free people of color rose from less than one percent to nearly 10 percent of blacks in the South.
19th century: American Civil War, emancipation, Reconstruction and Jim Crow and one of Withers's slaves. Withers sold Charley to a slave dealer and he was sold again in New Orleans. Of numerous relationships between male slaveholders, overseers, or master's sons and women slaves, the most notable is likely that of President
Thomas Jefferson with his slave
Sally Hemings. As noted in the 2012 collaborative
Smithsonian-
Monticello exhibit,
Slavery at Monticello: The Paradox of Liberty, Jefferson, then a widower, took Hemings as his concubine for nearly 40 years. They had six children of record; four Hemings children survived into adulthood, and he freed them all, among the very few slaves he freed. Two were allowed to "escape" to the North in 1822, and two were granted freedom by his will upon his death in 1826. Seven-eighths white by ancestry, all four of his Hemings children moved to northern states as adults; three of the four entered the white community, and all their descendants identified as white. Of the descendants of
Madison Hemings who continued to identify as black, some in future generations eventually identified as white and "married out," while others continued to identify as African American. It was socially advantageous for the Hemings children to identify as white, in keeping with their appearance and the majority proportion of their ancestry. Although born into slavery, the Hemings children were legally white under Virginia law of the time.
20th century Racial discrimination continued to be enacted in new laws in the 20th century, for instance the
one-drop rule was enacted in Virginia's 1924
Racial Integrity Law and in other southern states, in part influenced by the popularity of
eugenics and ideas of racial purity. People buried fading memories that many whites had multiracial ancestry. Many families were multiracial. Similar laws had been proposed but not passed in the late nineteenth century in South Carolina and Virginia, for instance. After regaining political power in Southern states by
disenfranchising blacks, white Democrats passed laws to impose
Jim Crow and racial segregation to restore
white supremacy. They maintained these until forced to change in the 1960s and after by enforcement of federal legislation authorizing oversight of practices to protect the constitutional rights of African Americans and other minority citizens. In 1967 the United States
Supreme Court case
Loving v. Virginia ruled that anti-miscegenation laws were unconstitutional. In the twentieth century up until 1989, social service organizations typically assigned multiracial children to the racial identity of the minority parent, which reflected social practices of
hypodescent. Black social workers had influenced court decisions on regulations related to identity; they argued that, as the biracial child was socially considered black, it should be classified that way to identify with the group and learn to deal with discrimination. By 1990, the Census Bureau included more than a dozen ethnic/racial categories on the census, reflecting not only changing social ideas about ethnicity, but the wide variety of immigrants who had come to reside in the United States due to changing historical forces and new immigration laws in the 1960s. With a changing society, more citizens have begun to press for acknowledging multiracial ancestry. The
Census Bureau changed its data collection by allowing people to self-identify as more than one ethnicity. Some ethnic groups are concerned about the potential political and economic effects, as federal assistance to historically underserved groups has depended on Census data. According to the Census Bureau, as of 2002, 75% of all African Americans had some degree of multiracial ancestry. The proportion of acknowledged multiracial children in the United States is growing. Interracial partnerships are on the rise, as are transracial adoptions. In 1990, around 14% of 18- to 19-year-olds, 12% of 20- to 21-year-olds, and 7% of 34- to 35-year-olds were involved in interracial relationships (Joyner and Kao, 2005). The number of
interracial marriages as a proportion of new marriages has increased from 11% in 2010 to 19% in 2019. ==Demographics==
