Highlighting the case of an African-American couple from Michigan, a civil rights group is expected to release a national report today that says real estate agents in metro Detroit and across the country often steer home buyers toward neighborhoods based on their race. The report by the National Fair Housing Alliance reveals that three out of four testers in metro Detroit were pushed toward certain communities because of their skin color. George Galster, professor of urban affairs at Wayne State who has studied racial steering for three decades, said that the report is troubling, but not surprising. \"At an individual level, it\'s a violation of fundamental human rights,\" Galster said. \"At a social level, steering perpetuates racially separate neighborhoods.\"
