Marriage between people of different racial categories now accounts for about what share of all marriages?

The answer is: 7.5 percent.

Explanation:

The percentage of interracial marriages has grown across the United States, although it is still a minority compared to the total percentage of marriages, according to the United States Census Bureau. From this 7.5%, the majority of interracial marriages are between non-Hispanic whites and Hispanics. And although interracial marriages have experienced a steady growth overall, since they became legal, in 1967, growth has also varied by state and county.
