Kurt Metzger, demographer with Wayne State University\'s Center for Urban Studies, said Oakland County's Democratic shift has stemmed in part from growing populations of black, Jewish and Hispanic voters in the county, many of whom have migrated from Detroit and Wayne County. \"You tend to think of African Americans as this kind of across-the-board voting demographic, and therefore, as the African-American population increases across Oakland County, that drives the Democratic vote,\" Metzger said. But, he added that within Oakland County there has been a newer movement of more upwardly mobile blacks from places like Southfield to Farmington Hills, West Bloomfield and Commerce Township. Along with that socioeconomic movement could come a change in voting patterns.
