According to this study, interracial relationships are on the increase in the U.S., but decline with age:

Interracial relationships and marriages are becoming more common in the United States, according to a new Cornell University study.

The number of interracial marriages involving whites, blacks and Hispanics each year in the United States has jumped tenfold since the 1960s, but the older individuals are, the less likely they are to partner with someone of a different race, finds the new study.

“We think that’s because relationships are more likely to be interracial the more recently they were formed, so younger people are more likely to have interracial relationships. This trend reflects the increasing acceptance of interracial relationships in today’s society,” said Kara Joyner, assistant professor of policy analysis and management at Cornell and co-author of a study on interracial relationships in a recent issue of the American Sociological Review (Vol. 70:4).

Although more young adults are dating and cohabiting with someone of a different race, the study found that interracial relationships are considerably less likely than same-race relationships to lead to marriage, though this trend has weakened in recent years.
