I would agree with Sweetpeach on that. It's actually a prett stark contrast - I used to take the LIRR from Atlantic Ave, so you pass through East New York on the way home, which is a low income area, and you see a lot of clotheslines and things hung between buildings. As you edged into more affluent areas, you don't see that.
Where I grew up in Queens was pretty suburban and middle class, and while you could hang out your laundry, I didn't really notice people doing that unless it was some of the people of the older generations.
