Suburb of Cleveland, Ohio.
I walk about 0.3 miles to work every day, so its really hard for me to see homeless people there. At work, oh, I'm sure that some of the people that walk into the library are homeless, but I don't ask. I can only think of one person that looked homeless in the library.
However, if I have to drive into downtown Cleveland, I see a fair number of homeless. I'd have to say they are mostly 30+ years old. I don't recall ever seeing kids.
