If a homeless person walks up to you and aggressively threatens you as you are passing by, no crime has occurred. But if you're an SF native, you've learned to shrug it off as a commonplace occurrence. You've learned to become thick skinned towards these incidences. And when a real crime has happened, you'd likely assign more gravitas to it.
This is why there is a disconnect between numbers and quoted statistics and how people feel.
Depending on what they say, isn't that still technically "assault"? Or "disturbing the peace"?
Also, if there's poop all over the sidewalks, those are all crimes too.
The problem is that all these petty crimes are generally never reported, and certainly not acted upon by police. So they never show up in the crime statistics.
There's a disconnect between the numbers and quoted statistics and reality, because the statistics come from the police, and their reporting isn't accurate. It isn't accurate anywhere of course, because police aren't perfect and many crimes go unreported for various reasons, but to SF natives, it may seem that this is worse in SF than other places, or in SF in earlier times.
Some guy / lady yelled at you for 10 seconds aggressively. Are you now going to call the cops / file a police report?
I think a majority of people would just move on with their day. So yes, to your point, this wouldn't show up in any statistics.
Interestingly, San Francisco's population declined from 775,000 in 1950 to 679,000 in 1980.

As to ease when you "start extremely high" -- SF is now safer, when it comes to violent crime, than most major cities in the US. What it does have is an extremely high rate of quality of life crime.
Conversely it’s also had a consistently higher property crime rate.
An undesirable place that washed up people ended up, riddled with crime and violence.
I think I might be getting the story wrong, but I recall hearing there used to be much more crime.
I think where to draw the line is this "undesirable place" business. That's highly subjective, judgemental, and can cause you to lose sight of a lot.
I wouldn't put too much weight in those kinds of comments.
I really don't understand what you're talking about.
