(New American Media) — African-Americans once were clustered so heavily in urban areas that the terms “black” and “inner city” came to be used almost synonymously. According to the 2010 U.S. Census results, that time is history. While blacks have by no means vanished from cities, unprecedented numbers have headed for the suburbs or left the big cities of the North and headed south. As legislative districts are redrawn, nonpartisan groups and both political parties are watching how this unexpected migration will affect local and state elections. Moreover, redistricting experts say the black exodus from cities such as Detroit, Cleveland and Philadelphia contributed to placing Michigan, Ohio and Pennsylvania among the 10 states that will lose congressional seats because of reapportionment after the census. With Republican governors in 29 states, the GOP has greater influence over redistricting than Democrats.
