Not even close, unless you own a shop (in which case, in some areas, life can undeniably be exasperating and miserable). The vast majority of high street crimes are shoplifting or possession (or drinking in alcohol control areas) and an astonishingly large number are attributed to a tiny, tiny number of people.
There are high crime areas in most towns in the UK where you will feel pretty safe, because the crime is simply not directed at you.
When it does spill over into personal violence, it is the aforementioned handful of people with drug problems. It’s worth noting that one incident involving three people is likely to result in a dozen recorded crimes. And a British town of sixty thousand people will have so few of these prolific individuals that they themselves commute to neighbouring towns to steal.
Worth remembering also if you are an American that in the UK we have not decriminalised marijuana, so there are drug possession and small-scale dealing crimes in there too.
