In spite of laws that supposedly ended segregation 4 decades ago, blacks and whites in this country continue to be very much segregated. According to this report, 75% of African Americans (who make up 12% of the US Population), live in only 16% of the US Census Tracks. There is a complete US map available at the link to the report.
Meanwhile, I've pulled out the map of the Kansas City and there are no surprises. The grey areas represent census tracks that are 50% or more Black, while dark red areas are 0% Black (you can click on the pic for a larger image). This helps us understand how it's become that schools are actually more segregated now than they were 40 years ago.
It's just another reminder of how divided we still are as a nation, and as a city.
