A group of 5 homeless people in each of the cities i've lived there would have been a huge group.
I've continuously encountered groups of 20-50 homeless people living in Boston, NYC, Miami, etc.
That's an order of magnitude more than what I consider "normal".
The west coast is another order of magnitude higher, with groups of 100s of homeless people around seattle, san francisco, san diego, LA, etc.
But that not makes the situation in the east coast cities i've visited "good". I consider the situation in the east coast "horrible", and in the west coast "war-zone like", when compared with the cities where I've lived in europe (madrid, barcelona, milan, munich, stuttgart, etc.).
