North County was previously where all the middle class white people went after fleeing the urban core. Then as more African American families moved in to get away from urban decay, the white population moved to suburbs south and west of the city. This isn’t civil rights history, either – it’s been an ongoing process as recently as the 90s. My (white) dad grew up in Blackjack, just a short ways from Ferguson, and his parents only moved out of the area around 1995. When the unrest around Michael Brown’s death kicked off, he turned on the evening news to see the supermarket where my grandmother used to buy groceries going up in flames.
