Frankly most people, including the OP, will have no clue about how much crime is in an area. Even the published statistics are inaccurate.
Much of it is very hidden. Drug dealing (lots of people don't seem to see it!), County Lines drug running, domestic abuse, rapes, thefts, online frauds, postal scams, phone call scams - I assure you it's happening all around you. And a lot of it isn't reported to the police.
