ASSOCIATED PRESS -- Nov 2 -- A new study by researchers at Cornell University and the University of Pennsylvania found interracial relationships, although on the rise, are significantly less likely than same-race relationships to lead to marriage. Though this trend has weakened in recent years, the rate of interracial marriage was still relatively uncommon in 2002, with only 2.9% of all marriages being interracial, according to the Census Bureau. The study found interracial relationships were most common among young people. Hispanics had the highest rate of interracial relationships, with 45% of 18 to 19-year-olds and 33% of 24 to 25-year-olds in interracial relationships in the early 2000s, compared with blacks (20% and 14%, respectively) and whites (16% and 12%, respectively). Asians appear to be comparable to Hispanics in terms of rates of interracial involvement. Researchers used data from the National Longitudinal Study of Adolescent Health and the National Health and Social Life Survey.
