First, the selection criteria for the cities covered in the article are completely unclear - for example, there's not a single city in Germany mentioned.

The text itself is also inconsistent. "Four of the top five cities — Bradford, Coventry, Birmingham, and London — are located in the United Kingdom." However, London is on place #15 according to the data presented.

It's probably best to ignore this drivel. Though Bradford felt pretty bad when I was living around the corner in Leeds a decade ago... :)

First bias is "perception", which is influenced by how media want to communicate and who own them - in France, mostly right wing billionaires. There is no actual correlation with actual, real, statistics.

Second, by who answer the survey - often people concerned about insecurity, which is a topic from the right.

Finally, there is no control on how many times you can vote, and some people demonstrated that with very few knowledge, you can completely change the results by sending thousands of vote [1].

The fact that Nantes is deemed highly insecure in France is also the consequence of this city being socialist and the place where police killed a guy named Steve during a party. So these attacks on Nantes being dangerous can also be interpreted as a backlash[2].

Please Hacker News, you're better than this, don't fall in this trap...
