Jews in America have had a complex relationship to race. At times, they have been described as a racial minority, whereas at other times, they have been able to assimilate into the white majority. Jewish status has largely depended on whether white Americans felt, in any given moment, socially secure. Jews have therefore fared better during times of economic prosperity. This social instability has strongly affected their relationship to African Americans. Jews, who have a strong sense of themselves as outsiders, have often identified with African American struggles but feared that overt solidarity would endanger their own status as white. Nevertheless, American Jews were disproportionately represented in the civil rights movements. Lastly, while American Jewish are predominantly Ashkenazi, which is to say of Central and Eastern European heritage, contemporary American Jewry is increasingly racially diverse, in part because of Jewish immigration from other parts of the world but also because of interfaith marriage, conversion, and adoption. This increased racial diversity has caused problems in the contemporary American Jewish community, but it is also changing the face of it.
