While a person who is not Roma only needs to send two messages to a landlord or real estate agent before they can view a rental property in Hungary, a member of the Roma community has to send nine. This is true even if they work as a dental technician. Researchers from CEU and ELTE conducted a representative study on discrimination against the Roma in the Hungarian rental housing market.
Antizyganism is officially sanctioned in much of eastern Europe. A few decades ago, in either Romania or Bulgaria (IIRC), a nationalist government relocated all Roma residents to a specific set of apartment blocks, moving non-Roma residents out to make room, and then designated the grounds of the blocks to be a new municipal landfill.
