Yeah, kinda interesting to watch, but if you were going to do a deep dive on this subject (and others like j*b opportunity, things to do, weather, schools, etc.) you might do better with "Places Rated Almanac."
https://www.goodreads.com/book/show/13197792-places-rated-almanac
My copy is maybe 25 years old (heh, heh, it helped me make up my mind that Honolulu was where I wanted to live.) IIRC it compares almost 400 places with 8 or 10 "aspects" like crime, weather, etc.
It's kinda funny how they w*rk out as, for instance they consider weather in terms of average temperature above or below 65 degrees F (points lost for either above or below.) Dis haole boy tink 65 F is too donn cold. Our most likely temps in winter are 70 at night and 80 in the day. Lots of locals run around in shorts - and winter coats in the winter. Not dis haole boy, but grab extra blanket in da winter time.
So as long as you know how each rated aspect is developed, you can put together your own criteria (heh, heh, forget j*b opportunity for instance.)
The video sort of touched on the idea that there are safer and less safe neighborhoods. I can point them out by now in Honolulu and my gut would tell me if I didn't know. SO "bad crime" is an average and may not apply to the area of a city you like otherwise.
You gotta go there and check it out day and night, summer and winter to really know about a place. Trust but verify. YMMV
