In comments below, JzB asked what my source for that data was. Well, the source is a U. Cal. study published in late 2009, which Project Censored notes as one of their top censored stories of 2010.
The primary reason why schools are segregated today is housing segregation, combined with the "independent school districts" in Texas and the West. That is why school segregation is worse in Texas and the West than in the South -- in the South, school districts are principally county-based, with the school district lines being the county lines. In Texas and the west, by contrast, it's possible to create "independent school districts" that encompass only the white neighborhoods and not the neighborhoods inhabited by brown-skinned people.
Thus for example in San Mateo County California, if all students in the county were in the same school district, the school district would be 51% white, 22% Asian, 22% Hispanic, and roughly 5% African-American and other. Instead, Palo Alto Unified School District, which excludes primarily-Hispanic East Palo Alto, had these demographics in 2005-2006: White, 52.2; Asian 25.1; Hispanic 7.9; African-American and other, 4.7%.
Meanwhile, just across the US101 freeway in East Palo Alto, the Ravenswood ISD has these demographics: Hispanic 70%, African-American 20%, Pacific Islander 9%, and other (including white) 1%. Note that Ravenswood is a K-8 district, East Palo Alto's high school students attend Sequoia Union high schools in Redwood City -- despite the fact that Palo Alto's high schools are closer. But wouldn't want *those* people in the very exclusive Palo Alto schools, right?
So anyhow, that's how it goes. We pretend that America is a racism-free land where everybody of every origin goes around hand in hand singing kumbaya... but the reality on the ground is anything but.
