Forum user claims mass immigration to Spain began under Aznar

Mass immigration began with Aznar, not Sánchez

When did Spain stop being a country of emigrants and become a major recipient of foreign population? In a forum thread, several participants argue that the quantitative leap occurred from 1999 onwards, during José María Aznar's second term, noting that by 2004 the volume was structurally different from the previous decade. According to these users, those who place the start under Zapatero or Sánchez are mistaken.

What the data cited by forum users says

The statistical series they cite does not come from the INE (Spain's National Statistics Institute), but from calculations circulating among participants. They claim that during the 1990s, the number of foreign residents in Spain was residual, with only a testimonial presence in markets and intensive agriculture. They pinpoint the turning point between 1999 and 2000, coinciding with the real estate bubble and full integration into the euro. In just six years, between January 2002 and January 2008, approximately 5 million people of foreign nationality would have been registered in the municipal padrón (resident registry), according to analysts who reconstructed the series.

The year-by-year breakdown allows these forum users to see who pressed the accelerator and when. In Aznar's last full year, from December 2002 to December 2003, 720,000 people would have entered. Under Zapatero, between December 2003 and December 2007, the figure would rise to 3,121,484 over four years, averaging 780,000 annually. The difference between one period and the other is not one of magnitude, but of continuity. The tap was already open.

Why is Aznar credited with the start rather than González?

Because, according to these users, the measurable phenomenon—sustained annual entries exceeding half a million—did not exist before 1999. Under Felipe González there were regularizations and established communities, especially in Madrid and Almería, but the aggregate volume did not alter the country's demographic composition. The Ley de Extranjería (Foreigners Law) allowing de facto registration for anyone present in Spanish territory was approved and consolidated during the Popular Party era, and has not been repealed since. This would be the administrative mechanism that turns scattered arrivals into a massive, recorded flow.

Some nuance that the true trigger was external: the Arab Spring, destabilization in the Sahel, and migration decisions by the German chancellor would have reconfigured global flows. It is a reasonable argument to explain the composition of arrivals, but not to deny who peine the domestic door. Another current argues that the determining factor was purely economic: a Spain in the midst of its construction miracle needed cheap labor and found it where it existed.

The subsequent accelerator: from Zapatero to Sánchez

What happens afterwards does not refute the starting point; according to these forum users, it confirms it. Zapatero maintains and intensifies the pace, Rajoy partially slows it down during the crisis, and under Sánchez the volume escalates again to figures that official records themselves acknowledge as incomplete. Circulating calculations place the population of foreign origin, including the second generation, at around 10 million people, with projections reaching 14 million if descendants and non-registered residents are included.

The discussion about each government's role is legitimate. What does not withstand comparison with the statistical series, according to these users, is the thesis that the phenomenon begins with the left. Aznar's PP did not just fail to close the door: it installed it with frame and hinges.

The uncomfortable conclusion for everyone is that the debate over who started it is of little use when we have spent a quarter of a century arguing the same thing. The graph has no political tonalidad. It has years.
