Concentrations of poverty shown on Myron Orfield’s maps lunge deep into the suburbs, suggesting a dynamic that could leave inner-ring suburbs like Brooklyn Center, Columbia Heights and other suburban communities as beleaguered as north Minneapolis, Orfield believes. Orfield, a former Democratic lawmaker, author and expert on regional growth issues, said changes in Twin Cities’ suburbs have been “really dramatic,” but not unexpected. Orfield views a debilitating cycle at work in a growing area of the suburbs, one creating low-opportunity neighborhoods, struggling schools and stressed local government. He depicts it as fueled to a great extent by a failure at providing affordable housing equitably across the entire metro area, a failure he places at the doorstep of the Metropolitan Council. If the older suburban areas would unite with Minneapolis and St. Paul and insist newer suburbs do their fair share in terms of affordable housing, the tide could be turned, Orfield said.
