In America, racial and ethnic categories have always been seen as absolute: black or white, Latino or Anglo. But Joel Crohn, author of Mixed Matches: How to Create Successful Interracial, Interethnic, and Interfaith Marriages, says that a quiet revolution is causing society to redefine race. According to Crohn, the number of black-white married couples has tripled over the past two decades; the majority of children born to a Japanese-American also have a white parent; and in the last generation, Jewish intermarriage skyrocketed from less than 10 percent to more than 50 percent. On Feb. 28, Crohn will give a luncheon lecture at the ANA Hotel; call (202) 659-5135 for more information.
