A Sept. 9 Style article on the PBS series "An American Love Story" misinterpreted Census Bureau data on interracial marriages. In 1997, there were a total of 311,000 married couples with one black and one white spouse, an increase of more than 50 percent since 1990. The bureau does not track the proportion of each year's interracial marriages.
