Busing failed in many areas, such as Prince George’s County, Maryland, because many people pulled out of the public schools.
In that county, at the time busing started, the total school population was about 76% white and 24% black. Within about 10 years, the school system was majority black. And eventually, black parents went to court, asking for the court order for busing to be lifted, because they were seeing their black children bused across the county to majority black schools anyway.
As I understand it, a number of whites decided to either move or put their children in private schools. And few whites have been moving to Prince George’s County in recent years. Nowadays the county is majority black, as is the school system. Unfortunately their schools have major problems.
