Europe's housing affordability crisis is widespread, though its impact varies significantly by location. A study by Vienna University of Technology, published in the Journal of Maps, examined how much housing people can afford when allocating 33% of their income to mortgage or rent. The findings reveal that 44% of Europeans live in towns or cities where they can only afford homes smaller than 50 m2, based on local incomes and property prices. When looking at rental housing, the figure falls slightly to 39%, highlighting persistent affordability challenges across the continent.
