Description

Founded in April 2009, Numbeo claims itself to be a "collaborative online database" which enables users to "share and compare information about the cost of living between countries and cities".[3] The Numbeo website is operated by Numbeo doo, a company registered in Serbia. The founder of Numbeo is Mladen Adamovic.[4] As of 2017, Numbeo was the largest database of user generated data about cities in the world.[5] As of 2020, this possibly applied to (user generated) data on housing prices as well.[6]

Criticism of accuracy

In 2012, columnist Alistair Walsh suggested in an article written for the website Property Observer, that Numbeo's information is based on what people say and should be taken with a grain of salt. This is because no third party check or audit on the accuracy of data exists.[7]

In 2017, a Swedish man showed how easily Numbeo stats could be manipulated, by pushing the Swedish city of Lund to become the most dangerous city in the world on the website's "Crime Index Rate" in less than a day. Trulsson added that Numbeo should hardly be considered stats, as anyone can change the data, as many times as they want, in complete anonymity.[8]

In 2022, a Numbeo claim that Bradford, England was "Europe's most dangerous city" went viral on social media and was reported on in British press.[9][10]

In 2022, French newspaper Le Figaro used Numbeo's ranking to compare violence and insecurity and titled "Insecurity: Nantes, Paris, Marseille, French cities unscrew in the world ranking of the safest cities" without criticism on the method of calculation, which is based on ‘reviews’ left by anonymous users, even if numbers are not realistic, like saying France is more dangerous than Mexico. While Mexico have seen at least 13 journalists killed in 2022, no one have been killed in France.[11][12]
