DiveIn Miniserie Educational Segregation in Spain Ep. 3: The Causes

In this third episode of our DiveIn miniseries on school segregation in Spain, we move beyond the headlines and ask a difficult question: What actually causes school segregation in Spain and the Basque Country?

After following the grassroots movement pushing the issue into the Basque parliament, we now dive into the deeper structural forces shaping who attends which schools—and why. Through conversations with leading researchers and policy experts, this episode unpacks the complex web behind segregation: publicly funded private schools (escuelas concertadas), school choice policies, hidden fees, language politics, middle-class flight, and cultural barriers facing immigrant families.

You’ll hear how Spain’s dual school system creates powerful incentives for social sorting, but also why the story is far more complicated than simply blaming private-public partnerships. Experts challenge simplistic explanations and reveal how segregation is increasingly happening within school networks—including inside public schools themselves.

This episode also explores one of the most fascinating and politically sensitive issues in the Basque Country: language as a mechanism of segregation. Can bilingual and Euskera immersion programs unintentionally separate students along class and immigration lines? And how do schools created as symbols of cultural resistance become part of a system producing inequality?

Along the way, Federico connects these debates to the United States, comparing Spain’s segregation patterns with the long history of housing discrimination, school choice, charter schools, and white flight in the U.S.
