Spain adds 500,000 people annually but builds only 100,000 homes

Reports of a two-bedroom apartment near Madrid listed at 1,400 euros per month and rented within weeks highlight the tension in Spain's housing market. An El Periódico article argues that immigration is not driving rental prices, but rather a shortage of supply and the prevalence of short-term tourist rentals. This debate has sparked numerous counterarguments, with most analyses pointing to a mismatch between population growth and new construction. Aliança Catalana president Sílvia Orriols linked these factors during a tenants' union protest, and the issue has since entered public discourse.

How much population enters annually, and how much housing is built?

The figures are stark and difficult to ignore. The most common statistic cites 500,000 additional people per year via migration, totaling two million over four years. Some estimates suggest annual entries of 600,000, 700,000, or even 750,000, depending on whether official registers or uncounted residents are included.

On the other side of the scale, completed new housing ranges between 80,000 and 100,000 units annually. A key data point: over the last decade, Spain has created 43% more households than new homes built. The registered population reached 48,592,909, adding 507,548 in a single year, a 1.06% increase.

The arithmetic requires no embellishment. If hundreds of thousands of people join the population each year while fewer than 100,000 houses are completed, the available stock per capita shrinks. Arguing whether this is due to "immigration" or "lack of supply" is, fundamentally, arguing about the same thing. The problem lies in treating it as an abstract entity, independent of the excess demand that fuels it.

The law of supply and demand, explained simply

To illustrate the basic issue, a recurring thought experiment involves moving 10,000 people to Zamora, where the average square meter costs 960 euros, and observing the impact on prices. The conclusion is that basic economic laws are easily understood, even if later invoked to deny them.

The most circulated comparison involves 10,000 new tourist apartments per year versus 600,000 annual entries. The implicit question—what weighs more in the market—is largely answered in the comments. Some note that the chain does not end with rentals: if demand significantly exceeds supply, purchase prices rise, along with the profitability required by landlords.

Tourism, foreign capital, and subdivided rentals

The article points to tourist use as a key culprit. The most common counterargument is that many areas around Madrid have no tourist apartments, yet rents continue to rise. Another contributor adds a layer: high-net-worth foreign buyers who pay cash in central neighborhoods, often with golden visas, shifting pressure to bordering areas.

At the other end of the market, there are reports of old, nearly uninhabitable apartments shared by multiple families, with costs of 150 euros per family per bedroom, and properties sublet by room at inflated prices. All this tensions the market both above and below, according to those who have witnessed such cases firsthand.

Why question the authors of housing studies?

The credibility of the source is also under scrutiny. It is argued that many housing reports are sponsored by actors interested in increasing population, and certain tenants' organizations are criticized for their funding and meeting locations. This is slippery ground: criticizing a study can be legitimate without making the accusation true, which is often made without evidence.

The profile of those arriving is also debated. It is claimed that the education level of immigrants in Spain is the lowest in the EU, including Portugal, and has remained stagnant since the early 21st century, with language and geographic proximity as attracting factors. These claims should be read as such.

From salary to rent: the argument that flipped

Notably, the discourse has shifted. A few years ago, the complaint was that foreign workers depressed wages; now, the same group is blamed for increasing living costs. In between, public aid and the minimum vital income are mixed, with estimates suggesting up to two million benefits tied to temporary jobs.

Criticism is not limited to newcomers. It also targets landlords who withdraw housing from the rental market due to legal insecurity regarding squatting, a factor that further reduces available supply and is rarely measured in price studies.

The final surprise

When population was studied in basic education, Spain had 38 million inhabitants; now it approaches 49 million. The market performs no magic: it only adjusts prices, and the person signing the contract pays the adjustment.
