Overcrowding and urban decay are soaring in Spain
The combination of soaring housing prices, stagnant wages and a growing migrant population has pushed the country to overcrowding levels that double the European average in just six years. Official data already show that four million people live with severe difficulty making ends meet, but the reality in specific Madrid neighbourhoods reveals a deeper decline: slum flats, run-down playgrounds and degraded public spaces.
Overcrowding is advancing unchecked across the EU
According to recent reports, Spain leads the increase in overcrowding in the European Union, with a rate that has practically doubled in six years. As rents soar, one in three rooms for rent already exceeds 400 euros a month. This pressure is forcing many families to share housing in extreme conditions: slum flats housing up to 40 people have been found, with tenants paying 100 euros a month each, generating 4,000 euros a month for the landlord.
Newly built neighbourhoods that are ageing badly
Examples such as Las Tablas, Valdebebas and Montecarmelo in Madrid illustrate the phenomenon. These are neighbourhoods planned two decades ago which, despite good transport links, lack sufficient green spaces, sports facilities and local shops. Residents complain about deteriorated playgrounds, lack of shade in summer and traffic problems. Property prices, however, remain exorbitant: 55 square metres in a working-class Madrid neighbourhood are going for 369,000 euros.
The middle class is fading away and conflicts are emerging
Wage precarity — with many workers earning 1,200 euros a month — and the impossibility of moving out are creating a new middle class barely surviving in rented rooms or at their parents' home. At the same time, the concentration of vulnerable populations in certain areas has sparked neighbourhood tensions and a greater police presence. The institutional response, for now, is limited to one-off operations against illegal tourist flats and evictions over structural defects.
Judging by the indicators, the trend shows no sign of improvement. Without a housing policy combining affordable supply and rent controls, overcrowding and urban decay will remain the norm in the years ahead. The figures speak for themselves, but the story behind them is even harsher.
