At the same time, a majority (55%) say they have been subjected to racial slurs or jokes, and about one-in-four (24%) have felt annoyed because people have made assumptions about their racial background.

This high level of acceptance among Millennials holds true across ethnic and racial groups; there is no significant difference between white, black and Hispanic Millennials in the degree of acceptance of interracial marriage.
Compared with older groups, particularly Americans ages 50 or older, Millennials are significantly more likely to be accepting of interracial marriage.
The percentage of white Millennials saying they have black friends (56%) is about the same as the percentage of black Millennials who say they have white friends (55%).
There is little difference on this question between Millennials and Americans ages 30 to 49.
The Census Bureau first started allowing people to choose more than one racial category to describe themselves in 2000.
The gap between Millennials and other age groups is evident for all of the individual groups asked about, though the size of the gap does vary as Americans ages 50 to 64 and 65 and older are less likely to accept marriages to members of some groups (in particular, African Americans) than others (in particular, white Americans).
