About 40 percent of White Americans and about 25 percent of non-White Americans are surrounded exclusively by friends of their own race, according to an ongoing Reuters/Ipsos poll.
The figures highlight how segregated the United States remains in the wake of a debate on race sparked by last month's acquittal of George Zimmerman in the shooting of unarmed Black Florida teenager Trayvon Martin. President Barack Obama weighed in after the verdict, calling for Americans to do some "soul searching" on whether they harbor racial prejudice.
There are regions and groups where mixing with people of other races is more common, especially in the Hispanic community where only a tenth do not have friends of a different race. About half of Hispanics who have a spouse or partner are in a relationship with non-Hispanics, compared to one tenth of Whites and Blacks in relationships.
