Number of biracial babies soars over past decade

The Washington Post reports:

The number of mixed-race babies has soared over the past decade, new census data show, a result of more interracial couples and a cultural shift in how many parents identify their children in a multiracial society.

More than 7 percent of the 3.5 million children born in the year before the 2010 Census were of two or more races, up from barely 5 percent a decade earlier. The number of children born to black and white couples and to Asian and white couples almost doubled.
