I would not generalize over all of Europe, I generally would not want to live around the Paris poor while the Vienna poor are way more livable. To put it very, very bluntly, Turkish-Albanian-Serbian poor > North African poor. It is an incredibly insensitive way to put it, but this is simply what my experience boils down to. The former countries got historically more "westernized"/secularized/liberal/whatnot. I regularly train with the former types of guys as I go to a fairly cheap boxing gym. They are okay. A bit rough around the edges, may be a tad aggressive, but culturally compatible. Football > religion types of guys. There are places in/near Paris I would not go in, for the police / ambulance does not really dare to go in either.
