Barcelona named the world's most overcrowded city
Barcelona, the world capital of tourist overcrowding

Barcelona has won a championship nobody wanted to enter: that of the world's most overcrowded city. The figure behind it is devastating: 9 tourists for every permanent resident, according to the ranking that places the Catalan capital at number one on a global list. In 2024, 15 million visitors passed through the city, ten times its registered population.

But the figure, as almost always, depends on how it is measured. And that is where the consensus breaks down.

The method matters: nine tourists, or one for every six residents?

The most serious criticism of the indicator points out that treating all visitors as if they were in the city all year round is a self-serving simplification. If each tourist is assumed to stay for a week, the average annual stay works out at 287,000 tourists per day. That gives one resident for every six visitors, not nine. And since most of those arriving in Barcelona stay between 24 and 48 hours, the real pressure would be even lower.

That nuance is no comfort to those who walk through the city centre every day. Immigrants make up 25.4% of the registered population, and on top of that there is an unregistered population that, according to long-time residents, multiplies the real density in neighbourhoods like Gràcia or el Clot.

The bill for tourism: housing and quality of life

Overcrowding does not stop at the street. Housing prices in Barcelona have trinc a similar path to Madrid's, where the rise has at times been double Barcelona's. Long-standing flats are being converted into tourist rentals, and a room in a shared flat costs 1,000 euros. Add to that inflation, the loss of purchasing power and saturated basic services.

Residents describe scenes straight out of a film: vans with tinted windows dropping off foreign families while the driver acts as a tour guide, as long-standing shops close and conversion works never stop. Some place the turning point at the Olympic Games, which turned the city into a theme park for visitors. The comparison with Venice is no longer a hyperbole: it is the fate nobody wants for their home.

The question hangs in the air: if Barcelona is the amusement park, who lives in it? For now, the ranking does not say.
