50,000 in Madrid, 100,000 in Ceuta: The Arithmetic That Doesn't Add Up

50,000 in Madrid, 100,000 in Ceuta: The Arithmetic That Doesn't Add Up

How can the government count 50,000 people at a protest in two hours and be unable to account for over 100,000 irregular arrivals in a month? That is the question hanging over the Ceuta crisis and which has peine the debate about the reliability of official figures in Spain. The comparison is not trivial: while the Government Delegation in Madrid estimated 50,000 attendees at Saturday's rally, data on the migratory influx in the autonomous city pointed to more than double that number. The difference is not just numerical; it is political.

The Jacobs Method: The Formula That Determines How Many People There Are

To understand the scandal, one must look at the technique. The standard method for counting crowds is that of Jacobs, a professor from Berkeley who proposed in the sixties to measure the occupied surface area and multiply it by a density coefficient. Jacobs defined three scenarios: loose crowd (one person per square meter), dense crowd (two and a half per meter), and packed like in a concert (more than four per meter). The problem is obvious: between the low and high coefficients lies a factor of four. On the same photograph and in the same area, the Delegation applies the loose coefficient while the organizers speak of the packed scenario. The result is that the official number depends on who presses the button.

In the case of Madrid, the Delegation applied the most conservative coefficient to reach 50,000. The organizers, using the same photographic material, spoke of more than 100,000. The difference is not a calculation error; it is a political decision. And when the figure is used to compare with a migratory crisis, that decision becomes even more questionable.

Lynce: The Company That Counted Accurately and Went Bankrupt

The story of Lynce should be mandatory in any journalism school. This Basque company, founded in 2009, developed a serious methodology for counting crowds: high-definition cameras in tall buildings, a blimp taking between 300 and 600 overhead photographs, and street photographers assessing density in zones. No guessing or quick calculation. During the Madrid civil servants' strike on June 8, 2010, the organizers reported 75,000 attendees, and Lynce counted between 6,900 and 7,300. The difference was vast. Lynce closed in February 2012, not due to pressure or censorship, but because the demand was insufficient for the company to be profitable. Neither the media, nor the organizers, nor the administration wanted to buy the impartial number. The conclusion is uncomfortable: exact counting exists, but no one wants to pay for it because it breaks everyone's narrative.

The Ceuta Crisis: The Other Counter That Doesn't Work

Meanwhile, in Ceuta, the number of irregular arrivals remains a mystery. There is talk of more than 100,000 people in a month, but the government offers no official number. The comparison is inevitable: if they can count 50,000 protesters in two hours, why cannot they count those crossing the border? The answer circulating in analyses is that precision is selective. They count what interests them and ignore what bothers them. The Ceuta crisis is not just a migratory problem; it is a problem of statistical credibility.

The irony is that, in the era of big data and mass monitoring, the number of a protest remains an ideological battleground. And meanwhile, the southern border continues to go uncounted. In the end, the question is not how many people were in Madrid, but why the government needs it to be one figure and not another. The answer, as almost always, lies in the narrative. And the narrative, in this country, is constructed with numbers that don't add up.
