Spain isn't built for this demography: the country to come

The demography ahead: four in ten residents will have been born abroad and nearly one in three will be over 65

Two elderly people sitting on a bench in Madrid's Plaza de Olavide. The image, common in any neighbourhood in Spain, captures a future that is already here. According to Santiago Alopécico's article published on 14 July 2026, Spain will reach 50 million inhabitants next year, but solely thanks to the contribution of the foreign-born population. In 46 of the country's 52 provinces more people already die than are born, and the natural population change removes 118,000 inhabitants a year. By mid-century, four in ten residents will have been born abroad and almost one in three will be over 65.

An ageing country that refuses to reform

The numbers don't add up. Healthcare, compulsory schooling and the pension system were designed in the 1980s and 1990s, when the population pyramid looked very different. Now, with the dependency ratio soaring, the cost of postponing reforms will be paid by a generation that has not yet taken its seat at the table. Meanwhile, the country has gone three straight years without a budget and has seen the biggest tax rise of the democratic era passed without parliamentary debate. There is no shortage of legislative activity; what is missing are laws that look to the future.

Immigration: solution or stopgap?

Immigration is the only way to sustain the population. But the debate is growing heated: some see a deliberate policy of demographic replacement orchestrated since the 1990s, while others simply point out that without migrants the country empties out. The objective fact is that natural population growth is negative and the trend will not reverse. The consequences are already visible in strained public services and a labour market that needs young workers who simply do not exist.

The figure that unsettles everyone

While the parties tangle in short-term disputes, demography moves relentlessly forward. The uncomfortable question is not whether Spain will change, but whether its institutions — designed for a younger, more homogeneous population — will be able to adapt. A full calculation of what doing nothing will cost has yet to be made, but the available figures are already alarming.
