Warp raises a good point. Statistics tend to level the playing field quite unnaturally.
A 1:10,000 chance would be based on murders per the number of folks present. But reality might be that a financially stable, established family man (or woman), living in a relatively upper-class part of town, and of lawful and cautious habits, and with good situational awareness may face a 1:1,000,000 chance of being murdered. On the other hand, a young male living in the inner city, who uses and deals in street drugs, spends a lot of time out and about in rough areas late at night, and associates with other equally or more intensely criminal actors, may face a 1:10 chance of suffering homicide. Both contribute to the broader statistic, and both skew it out of relevancy for you as a visitor.
You, as a visitor fall somewhere in between. On the one hand, your exposure time is very low. On the other, you're on unfamiliar ground. But, you're probably likely to be at a rather high level of alertness because of that unfamiliarity. But you don't know the local actors/culture, and you may end up lost and wandering as a visibly vulnerable target for unpleasantness.
So much is up to the choices you make and how street smart you are that predictions of true risk are extremely hard to make.
