m Gen-Y; I've walked around my entire life, in all sorts of places, and have never been approached or robbed by anyone
If you want to play that game.... I would point out, that i've been approached on multiple occasions by people asking for cash, and I've heard from 5 or 6 different friends/acquaintenances
(a majority of these acquaintenaces female...) who at some time within the past 9 or 10 years that were mugged, robbed, or attempted to be robbed under threat of violence at gunpoint at different places at different times.
It is hard to tell what the risk will be for any particular individual, and there are many factors.
It IS potentially dangerous in that all the cash you are carrying might be stolen.
Although it is also likely that in a confrontation, your $1000 Cell phone, Driver's license, Wallet, and your credit cards would all be stolen, And you would likely be subdued, tossed in a ditch, or otherwise prevented from promptly reporting the theft of said CCs, so robbers have plenty of time to spend some $$$ in your name; They may also force you to hand over your Debit card or ATM PIN numbers, and make significant withdrawals from your bank accounts.
But in theory, a less brazen robber will only go for the cash, and your $$$ in other forms will be protected because of your limited liability for unauthorized charges --- You MIGHT be able to get some banking transactions reversed, And at the very least, there will be more tangible documentation of the crime than some cash you claimed to have been carrying.
ALSO, Because cash is so liquid and easy to conceal the fact it is stolen cash..... thieves are more likely to target cash. So the more people who are carrying around a lot of cash, or the more likely potential robbers THINK or BELIEVE you might be carrying around cash AND the more vulnerable a target, the more likely it is you might become a robbery or attempted robbery victim.
