Why did many schools remain segregated

If their would be more blacks than whites in a neighborhood, the schools would have not been as segregated as if the neighborhoods are whites>blacks. 

Many schools remained segregated as communities moved slowly to comply with the court's ruling in Brown v Board of Education. Since children usually attended a school in their neighborhood, segregation in public schools reflected the racial segregation of neighborhoods. In many cases, de facto segregation still existed.
