Valencia and 21st-century slums: 410,000 in substandard housing?
On January 11, 2026, Levante-EMV published a report titled "Slums in the 21st Century" estimating 150,000 people live in shacks, properties without utilities, or overcrowded conditions in the Valencian Community. However, headlines circulating on social media and forums have inflated this figure to 410,000. Where does this data come from? Is it an exaggeration or a warning of what is to come? It is clear that Valencia's housing problem has ceased to be a hallway rumor and has become a social emergency.
The dividing figure: 150,000 or 410,000?
The discrepancy is significant. The Levante-EMV article, linked to sources from the PSPV (Spanish Socialist Workers' Party) by some, cites 150,000 people in substandard housing. Yet, the debate has driven the figure to 410,000, representing one-quarter of the city's population. Proponents of the higher number point to vertical slums—buildings unreformed since the 1960s—and "pirate" rentals (without contracts or utilities) as inflating real figures. Others dismiss it as political manipulation to pressure the PP (People's Party) in the regional government. The reality is that even official census data, which placed Valencia's population at 858,178 in 2025 (a 2% increase), fails to capture thousands living in sublet rooms, industrial warehouses, or occupied houses.
Causes of an announced collapse
All signs point to a perfect storm: tourist and digital nomad demand has driven up rents—a flat costing 1,500 euros can jump to 2,800 upon renewal—while public housing supply is absent. Protected land (orchards, Albufera) blocks construction, and developers focus on luxury flats for foreigners. Meanwhile, immigration—particularly from Latin America—continues to rise: Valencia gains 17,000 residents annually, many with low incomes driving demand for substandard housing. The promised gigafactory (allegedly generating only 100 jobs) has spiked landlord expectations, with rent hikes of 50% already announced. The result is families losing child custody for failing to provide decent housing, or workers sharing 40-square-meter flats. As one analyst notes, "social peace rests on a minimum standard of living; when that breaks, the horizon fills with dark clouds."
The lingering question is whether regional and local administrations—in the hands of the PP with Vox support—can formulate a response before the social temperature exceeds 40 degrees. For now, the only certainty is that the number of affected people, whether 150,000 or 410,000, is growing faster than the solutions.
