School segregation, which had been in decline for twenty-five years, increased after the 1991 Oklahoma City Board of Ed v. Dowell ruling, which ended federal desegregation mandates. Since then, the emphasis has been on accountability measures that assume educational opportunities can be equally achieved in separate - affluent vs. poor - schools.
Furthermore, desegregation efforts never really targeted Latino students, who are significantly more segregated than their black counterparts, especially in suburban school districts. In Texas, California, and New York, more than 50 percent of all Latino students attend schools that are more than 90 percent minority.
Similarly, more than have of all black students in Michigan, Illinois, and Maryland attend schools that are more than 90 percent minority.
Housing policies play big role in this. Families with means move to wealthier areas where schools have more funding, more experienced teachers, and fewer teachers teaching outside their credentialed area. Those affluent families tend to be white and Asian. Disparate school funding formulas also play a huge part.
The US sees desegregation as something that was attempted and which failed, or as something that isn’t needed anymore. The reality says otherwise.
