Spain's Housing Crisis Is Boiling Over. Is America Approaching the Same Tipping Point?

An eviction in Madrid became a symbol of a national housing crisis. A comparison with the United States raises an uncomfortable question: How close are we to a similar breaking point?

I was in Toronto for work when a story on the morning news stopped me cold.

An 87-year-old woman in Madrid had been evicted from the apartment she'd occupied for more than 70 years.

Her name was María del Carmen Abascal, known to friends and family as Maricarmen.

On September 23, 2026, after a prolonged legal dispute involving the ownership of her building and the terms of her tenancy, she was removed from her home. The images were heartbreaking. An elderly woman, displaced from the place where she'd spent nearly her entire adult life.

But the story didn't end at her doorstep.

Within days, protesters were taking to the streets. Maricarmen's eviction became a rallying point for a growing movement against housing costs, speculative investment, and a political establishment many Spaniards believed had failed them.

On October 7, Maricarmen died, just two weeks after her eviction. Although an agreement had reportedly been reached that would have allowed her to return, she never made it home.

Her death intensified the protests, adding urgency to a confrontation already reshaping Spain's political landscape.

That sequence of events got me thinking about a distinction we don't discuss nearly enough in economics.

Was Maricarmen's eviction the cause of the unrest? Or was it simply the spark that ignited something much bigger?

The problem you can see versus the problem you can't

An eviction makes for compelling video. It has a victim, a location, and identifiable parties who can be held responsible.

A housing shortage is different.

You can't film the apartment building that never got constructed. You can't interview the family that never formed a separate household because the rent was unaffordable. You can't photograph the thousands of people priced out of a neighborhood they once considered home.

But those invisible outcomes accumulate.

According to the Bank of Spain's 2025 Annual Report, the country accumulated a housing supply shortfall of approximately 750,000 homes between 2021 and 2025.

In 2025 alone, Spain added roughly 240,000 households while completing just 92,000 new dwellings.

For every 100 new households formed, fewer than 40 new homes were completed.

The eviction didn't create this imbalance. It gave it a human face.

Then I looked at the American numbers

Spain's housing crisis might seem uniquely European, shaped by its rental regulations, tourism economy, demographics, and political culture.

But what happens when we compare the underlying housing shortages relative to population?

Zillow estimates that the United States has a housing deficit of approximately 4.7 million homes.

America's population is nearly seven times Spain's, making total shortages a poor basis for comparison.

Adjust for population, however, and an unexpected similarity emerges.

These estimates use different methodologies. Spain's figure reflects the cumulative gap between household formation and housing construction, while Zillow estimates unmet housing demand.

They aren't perfectly interchangeable measures. But the magnitude is striking.

Fifteen in Spain. Fourteen in America.

Two very different countries appear to be experiencing housing supply imbalances of broadly similar proportions.

Home prices tell a similarly unsettling story

Scarcity alone doesn't determine affordability. Interest rates, household incomes, credit availability, and geography all matter.

Nevertheless, another comparison caught my attention.

Using Spain's National Statistics Institute House Price Index and the U.S. Federal Housing Finance Agency's House Price Index, our research produced the following estimates for the decade ending in the second quarter of 2026.

In both countries, residential property prices have nearly doubled over a decade.

There are methodological differences. Spain's index covers new and existing residential properties, while the U.S. FHFA purchase-only index primarily measures homes financed through conventional conforming mortgages.

These are national price changes, not direct measures of household affordability.

Still, consider the parallel: two countries with very different housing systems, yet both experiencing enormous property appreciation alongside significant supply constraints.

Housing affordability is about more than house prices

To understand the political consequences of housing scarcity, we have to consider its effect on household finances.

In the United States, Harvard University's Joint Center for Housing Studies reports that 22.7 million renter households—49% of all renters—spent more than 30% of their income on housing in 2024.

More than 12 million spent over half their income on rent and utilities.

For millions of households, housing isn't simply their largest expense. It constrains virtually every other financial decision.

It influences whether people can save, relocate for a better job, start a business, or build a family.

Housing affordability is therefore not just a question of real estate economics.

It increasingly intersects with labor mobility, economic opportunity, wealth accumulation, and perceptions of fairness.

Those intersections help explain why housing can become such a powerful political issue.

Is there a tipping point?

This is where the comparison becomes both interesting and difficult.

Comparable housing shortfalls per capita don't mean the United States is destined to experience similar protests.

Housing markets are local. National averages conceal enormous regional differences.

Tenant protections, homeownership rates, public housing programs, and cultural expectations all influence how economic frustration manifests politically.

Nor is 15 missing homes per 1,000 residents some scientifically established threshold for civil unrest.

There is no universal housing-shortage ratio at which a population suddenly takes to the streets.

But that doesn't mean tipping points are imaginary.

Economic pressure can accumulate gradually while public reactions remain muted. Then an individual event gives the underlying frustration a common focal point.

An eviction, policy decision, price shock, or perceived injustice becomes the catalyst through which people express dissatisfaction that has been building for years.

The event itself may be small compared with the underlying economic forces. Its symbolic power can be enormous.

In Spain, Maricarmen's eviction became just such a symbol.

The question for Americans isn't whether we'll reproduce Spain's political experience. It's whether we're adequately accounting for the cumulative social consequences of our own housing imbalance.

When the data leaves the spreadsheet

I work in real estate data. Much of my professional life is spent understanding what numbers reveal about properties, markets, and economic behavior.

Data helps us identify relationships that aren't immediately visible. But it has a limitation.

A national shortage of 4.7 million homes is an abstraction.

So is a decade of 95% home price appreciation.

Even the finding that nearly half of American renters are cost-burdened can become just another statistic in a quarterly report.

An individual eviction, on the other hand, is intensely tangible.

The images coming out of Spain are what happens when data jumps off the spreadsheet and into the street.

And that's the distinction I keep returning to.

You can film an eviction. You can't film the hundreds of thousands of homes that never got built.

One is the spark. The other is the fuel.

I'm not predicting that Americans will soon be protesting housing affordability in the same way Spaniards have.

But given the underlying economic pressures, I wouldn't rule it out either.

Perhaps the more useful question isn't whether America is one viral video away from a similar movement.

It's whether we're paying enough attention to the conditions that could make such a movement possible.

International comparisons are directional; the shortage estimates and price indices have different underlying coverage and methodologies.
