They're not noticeable in that sense. There is just a homeless population where there was not before, and the existing hotspots have spread from a small street to a block or an area. There just seems to be more homeless people. The official statistics in Berlin support that. I have not looked at other cities.
One decade+ member of our small rental community is about to become homeless, on account of the way he chooses to live (messily, against city codes, with multiple yard vehicles, ignoring landlord/inspector).
Two years ago I think he still would have cared, perhaps even tried; but that spark (of life) is just gone.
