In the 21st century, segregation no longer requires "Whites Only" signs. It's enforced by lines of code. This episode investigates how algorithms used in housing, banking, and advertising silently sort people by race and income, creating digital barriers as rigid as any physical wall. We trace a single data point—a ZIP code—as it travels from a credit application to a predatory loan offer to an exclusionary ad for a luxury apartment. You'll hear from data scientists who've audited these opaque systems and community organizers fighting for algorithmic transparency.
