Why are many U. S. public schools segregated today?

Honestly it's all about the parents no one is born racist nor is anyone born into segregation. Parents choose how their kids are raised and what they believe.

Answer: Personally it is where the school is located I used to live in a small town in MO and there went many kids that had other races except Caucasian then I recently moved to FL and there where a lot of mixed/darker kids here. So its all about the location of the school.
