Record 1.1 million migrant pupils in Spain's schools, nearly 20% of students

1.1 million migrant pupils in Spain's primary and secondary schools now account for almost 20% of enrolment. The fiscal cost is fuelling the debate: they contribute less than they cost.

Spain's schools are overflowing: 1.1 million migrant pupils, 20% of the total

Data from El Español dated June 2026 confirm a historic record: more than 1.1 million foreign students in primary and secondary education, nearly one in five. The figures do not include children born in Spain to immigrant parents, which by some estimates could double the percentage to 50% of the total.

The economic cost of schooling

The economic breakdown is stark. A migrant pupil whose parents earn a precarious salary of 15,000 euros a year contributes barely 4,000 euros in taxes. Compare that with the 13,000 euros paid by a Spanish graduate earning an average salary of 35,000-40,000 euros. The fiscal gap does not cover the cost of education: a secondary school student costs the state around 6,000 euros a year. In short, the system subsidises years of schooling with a negative fiscal return in many cases.

Academic performance and consequences

Another line of argument points to the impact on quality: many arrive with a very low educational level and drag down the average performance of classrooms. Grade repetition and the need for extra support make the system even more expensive. And at 16, a significant proportion drop out of school to work in the informal economy or for platforms like Glovo, perpetuating the low contribution profile.

The debate on how to finance this mass schooling — whether by cutting other budget lines or taking on more deficit — is only just beginning. The data are on the table; the solutions, not so much.
