The foreign population will grow 20 times faster than the Spanish population in 2025

Moreover, this slight increase in the number of Spaniards is greatly influenced by Nationalizations. Without them, the total number of Spaniards would not grow either, because deaths exceed births. In fact, looking exclusively at data by place of origin, the number of people born in Spain decreased by 0.20% (80,434 fewer people).

A similar number of births and naturalizations

Although the National Institute of Statistics does not yet have nationalization data for 2025, last year’s data clearly indicate the same trend. In 2024, 252,476 nationalities were granted, corresponding to 322,034 births and 433,547 deaths. In practice, Nearly half The growth of the Spanish group came from people who were not born in the country. Furthermore, among those born here, 26% of those under 20 have one or two parents born abroad, and for those under 5 the percentage rises to 36%, according to a study by Funcas Panorama Social.

Population registry in Spain

With all this, Spain reached a new population record in this third quarter, reaching 49,442,844 people. Of these, 1 in 5 were born abroad, and in 2025 this group accounted for 122% of net population growth (445,294 new residents born abroad compared to an overall increase of 364,860 residents).

Without this influx, Spain would have lost 80,000 people In just nine months, and nearly half a million since the onset of the pandemic, the result of an aging population. A scenario that clearly challenges GDP, consumption and, more generally, the short-term financing of Social Security and the under-retirement system. But it would also dampen demand for housing and increase labor shortages, the deciding factor in wage negotiations in almost every sector.
