The reason why crime is lower in some times than in others

This year in Spain the levels of pollen concentration in the air they have been exceptionally high, according to researchers from the Xarxa Aerobiològica de Catalunya de l’Institut de Ciència i Tecnologia Ambiental de la UAB (ICTA-UAB). The allergic They had a rather complicated season suffering from the usual symptoms of nose and eye itching, sneezing, nasal obstruction, asthma and breathing difficulties.

But if you thought with him fall you were going to get rid, you take it clear. One of the main culprits of this pathology at this time is ambrosia pollen, a plant that causes many problems to those sensitive to environmental issues in the US and that can also be found in some areas of our country. In addition, experts ensure that the situation will worsen every year as the earth's temperature grows.

What do allergies have to do with crime? According to a study by the universities of Pennsylvania and Wayne State and published in 'The Daily Mail', the pollen high seasons They reduce the rate of violent robberies and crimes.


The Spanish balance of the last report published in 2016 by the Ministry of Interior states that since 2008, the year with the highest rate, the percentage continues to fall and continues to decrease. But within our own territory there are differences between cities: Gijón is the safest and Barcelona the least. In addition, the rate of criminal offenses in 2018 per 1,000 inhabitants of Barcelona is four times higher than that of the Asturian municipality. Is it then that in the Catalan capital there is a lower rate of allergies? Possibly not.

It is not just that people are not where crimes are committed, but that the fact of suffering them fundamentally changes the motivations

With previous data, both crime and population, in Spain 2,131,424 criminal offenses (offenses and offenses) were recorded last year, representing 45.61 per thousand inhabitants. Of the 63 Spanish cities that have a population over 100,000, 28 exceed the average rate.

There are no investigations in our country about the relationship with allergies, but in the US, only in New York City and compared with the situation of the previous year, the rate decreased by 6.7%, coinciding with the maximum point of allergens. In fact, in their 2018 study, published in the 'Journal of Health Economics', UPenn and Wayne State scientists analyzed data on the count of crimes and pollen in 16 cities and discovered that as the latter increased, crime fell in all violent areas.


So the conclusion reached by the experts was that murders, robberies and assaults They were frustrated for this reason. Rates fell 4% on average on days with higher pollen rates and the influence was most felt by New Yorkers, reduced their violent crimes by 7% on days in the highest percentile for pollen.

Interestingly, the study found that allergy season had no noticeable effect in property crimes such as vandalism or theft, but in terms of domestic violence it refers.

"The main way in which these allergies affect people can be through the manifestation of your physical symptoms. It is not just that people are not in the street, where crimes are committed, but that the fact of suffering them fundamentally change the motivations and plans a crime and underlines the extent to which violence responds to that situation, "the study authors explain.
