Foreign Workers Now Make Up 52.6% of Spain’s Construction Laborers

More than half of Spain’s construction laborers are now foreign workers, a sharp shift that highlights how vital migrant labor has become to keeping the country building.

Story Snapshot

Foreign workers make up 52.6% of Spain’s construction laborers, edging out Spaniards in that job category.
Since 2019, the sector shed 22,711 Spanish workers while adding 238,451 foreign workers, including dual nationals.
About 36% of all construction workers are now of foreign origin, across skilled and unskilled roles.
Other studies show the whole sector’s foreign share near one quarter to one third, underscoring different denominators.

What the new figures say about who builds Spain

Spanish media citing Randstad’s first quarter data report that 52.6% of construction laborers are foreign workers. The report says foreigners outnumber Spaniards in this specific occupation by almost 11,000 people. It also says construction has lost 22,711 Spanish workers since 2019 while adding 238,451 foreign workers, a figure that includes dual nationality. The same coverage places foreign-origin workers at nearly 36% across the entire construction workforce, not just laborers.

A separate labor-market review from 2025 listed “construction laborer” as the occupation with the highest foreign presence at 55%. That report also counted 386,507 foreign workers in construction overall, or 25.3% of sector employment. These numbers point to a split between occupation-level and sector-level measures. A majority exists in the narrow job of laborer, while the broader sector remains at roughly one quarter foreign, depending on the source and definition.

Why the numbers differ across sources

Different sources track different things: foreign-born people, foreign nationals, or workers of foreign origin. Some counts also include dual nationals. These choices change the denominator and the headline. A job category like “construction laborer” can show a foreign majority while the full sector sits lower. European and Spanish studies have long shown heavy migrant reliance in tough, lower-paid, and physically demanding roles, including on building sites, which helps explain the higher shares in unskilled posts.

Broader context from research groups says Spain’s foreign share in construction rose in recent years as demand for housing and public works stayed firm. One analysis places foreign workers at about 32% in construction, while an industry federation reports 20.7% in 2025. Banking analysts note the foreign share moved back toward mid-2000s levels as employers struggled to fill jobs. The direction is the same across sources, even if the exact percentages differ by method and scope.

What this shift means for wages, work, and policy

Employers say they face worker shortages, aging crews, and high dropout rates in training. Many rely on migrants to keep projects on schedule. That helps hold down delays and costs, but it also raises hard questions. Who invests in training? Who enforces safety on job sites? Who ensures fair pay so native and foreign workers both see a path to the middle class? These are practical issues that hit families, renters, and small builders alike.

For citizens across the political spectrum, the core concern is delivery. Spain needs homes, roads, and repairs done on time and on budget. If most entry-level crews are foreign, the system must manage recruitment, language, and safety well. Clear data also matters. Mixing “foreign-born,” “foreign national,” and “foreign origin” blurs the picture, feeds culture-war headlines, and hides the real task: building a steady, skilled pipeline that lifts workers and serves the public interest.
