Good evening all
I don't believe it's important to find the SAFEST countries, maybe those we would regard as GENERALLY safe. In any case, just about every country has its unsafe areas or circumstances. After 60 years of travel and over 50 countries across 5 continents, I have only ever been robbed once (and never threatened), in Belgium! However, I have found myself in a few areas where I felt uncomfortable, but nothing came of it. There are places where the norms for people selling goods or services, nor those of personal space, certainly don't correspond to mine. I was sometimes uncomfortable during my first visit to Morocco, but never felt unsafe.
I think Jonas makes a very good point regarding quality of life (or perhaps standard of living). Where that is highest, there is much less chance of crime, hence Anäis' comments about Monaco and the big cities of France. So, there are specific areas in even the most prosperous nations and cities where being alone might be threatening. Cultural opinions about women alone will also have an influence. Rather than consulting any list of "safe" countries, travellers should ask local advice about where and how they should travel.
Is there a line to be drawn between feeling uneasy, harassed and actually being unsafe? I would also suggest that some people do not fully understand the feelings of women, and the influence their words or actions have on them. If I were a woman, I would avoid some who post on these communities offering help or services, although I'm fairly sure they mean well.
Maybe we too have some unconscious biases about the sort of places we tend to feel more safe: stable northern European countries like Denmark, Netherlands, Sweden, Luxembourg?
