Immigration pushes Spain's population to an all-time high

Spain grows through immigration: 49.3 million inhabitants

Spain's statistics office (INE) has just published its Continuous Population Statistics with a milestone that frightens half the country and delights the rest: 49,315,949 people were living in Spain as of 1 July 2025. That is 119,811 more than three months earlier, the largest quarterly increase in the series, putting the population at an all-time high. The growth, however, is not down to births: the population born in Spain is falling, while immigration is doing the heavy lifting.

The INE figures: growth from abroad, decline at home

According to the statistics office, the number of foreigners rose by 95,277 during the quarter, to 7,050,174. Spanish nationals are growing thanks to 24,534 naturalisations, but the number of people born in the country fell by 18,120. In other words: without migration, the country shrinks.

More residents, more pressure: the case of Valencia

The economic debate is heating up in the regions that feel the impact most. Valencia is now approaching 5.6 million residents, half a million more than in 2021, with some of the worst per-capita funding in the country. More people means more housing demand, more hospital emergencies, more school desks, and a regional funding equation that many find hard to square.

A blessing for pensions or a ticking time bomb?

And yet, part of the analysis insists that immigration is the only solution for public finances headed for an ageing crisis. The problem, it argues, is not the arrival of people, but a labour market that fails to deliver quality jobs and an economic model overly dependent on tourism.

The striking figure: if the second quarter's pace continued, Spain would surpass 50 million in under two years. No one knows whether that is an opportunity or a powder keg ready to explode.
