The study, released in the middle of December, found a rise in interracial relationships especially with Asians, Hispanics, and Native Indians/Alaskan Natives.
But whites and blacks are also marrying other races more today than in the past. For instance, Asian women were far more apt to marry white or black men than Asian men were to find a relationship outside their race.
Some racial groups are more likely to intermarry than others.
Of the 3.6 million adults who got married in 2013, 58% of American Indians, 28% of Asians, 19% of blacks and 7% of whites have a spouse whose race was different from their own.
By the time of the American Revolution (1775–1783), the status of slave had been institutionalized as a racial caste associated with African ancestry.
During and immediately following the Revolutionary War, abolitionist laws were passed in most Northern states and a movement developed to abolish slavery.
Most of these states had a higher proportion of free labor than in the South and economies based on different industries.

Slavery in the United States was the legal institution of human chattel enslavement, primarily of Africans and African Americans, that existed in the United States of America in the 18th and 19th centuries after it gained independence and before the end of the American Civil War.
