Safety in Italy is a question I get a lot, especially from Americans; the short and sweet is that you're far more likely to be murdered/robbed/have something bad happening to you in your home country than in Italy. Some numbers to give an idea:

1. In 2021, there were 302 murders in Italy, 4 less than Memphis in the same year. Italy has 60 million people, Memphis 630 thousand.

2. In terms of theft and robbery, in 2021 there were 811,578 reports of theft and 22,093 robberies, of which almost 13,000 happened on what the government calls "public roads" - purse snatchings, that sort of thing. Again, for a country of 60 millions it's not that high.
3. If you look at "furti con strappo", meaning acts of theft happening on the road like pickpocket, purse-snatch and the evergreen 'Rolex nicking' the highest chance of that happening is in Naples, where there have been 68 reports/100,000 residents in 2021. I can't quite find an exact match for the crime, but if I look at Burglaries in NYC the rate is 141/100,000 (2018), and that's the lowest of the handful of cities I could be bothered to compare with (San Jose, San Diego, Boston)

So, bottom line: Italy is a very safe country, a lot safer than parts of the US. Sure, it's not Japan or other Asian countries where you can use your wallet to keep your place at a table while you go to the counter or the loo: if you walk around the Navigli at night with your bag open, you are bound to find our that your wallet is on its way to Quarto Oggiaro. Ditto if you leave your sat nav on the windscreen at night in via Nizza in Turin. But, overall, if you exercise a modicum of intelligence you'll be alright.

PS: please please please don't go asking around "Is it safe here? You know, the mafia..." when in country. It's quite insensitive. It's a bit as if I went 'round in the US asking if I'm safe because you have so many guns and mass shootings. I know this is a forum, a safe space for asking questions, and one won't know until you ask but I've heard it when in country (or here in London for that matter).
